S h a r e G a m e s Christopher G. Gunn 3174 Hawthorn Street San Diego, CA 92104 (619) 283-0472 DirBack is distributed as shareware on an "I trust you" basis and is not in any form to be considered public domain or free. Considerable effort went into creating the program and I am retaining full protection under the copyright laws. However, I also want you to be able to share my games with your friends. So, please feel free to hand on as many copies as you would like, as long as you include the original all of the original files. If you are going to use DirBack for your personal enjoyment, whether you got it from a distributor or a friend, please mail a check or money order to me at the above address. The registration fee for DirBack is $35. I depend on your registering to continue devoting full time to making fun to use programs that don't require you to adapt to the program. I'd also like your comments and suggestions. In exchange, I'll add your name to the list of those eligible for updates, contests, and 24-hour technical support. If you wish, you may use the registration form by typing PRINT DIRBACK.REG at the DOS prompt. Like all of my programs, DirBack is designed for color with a high resolution display and should run on most PC's and clones. DirBack does not use graphics and is compatible with almost any display adapter. There is a provision for disabling the sounds if you prefer to have DirBack work quietly. If you have any problems, let me know. GENERAL DESCRIPTION: DirBack is a different kind of backup program. Rather that create the usual DOS "backup/restore" style disks that require using RESTORE even to recover a single directory or file, DirBack creates directories and copies the files to and from any drive. The result of backing up your entire hard drive is a set of floppies, that duplicates all of the directories and files the way they exist on your hard disk. If you need a program or any combination of programs and files you can use DirBack, a disk manager, or the DOS commands to copy or execute them. The most important asset is DirBack will NEVER write an older file on top of a newer version and only spends time copying files that are missing or have changed. The other asset is peace of mind. DirBack automatically checks your primary system files, COMMAND.COM, MSDOS.SYS, and IO.SYS, (or the IBM DOS versions) and will report any time, date, length, or content change every time you execute DirBack. The three DirBack programs are also checked. DirBack does not use parity checks. Each file is checked, bit for bit, against files stored in DirBack's STASH directory faster than DOS can copy the files. The same VIRUS CHECK options are available each time you update your backup disks. Any file or program with a matching time and date on the destination disk is checked to verify both files are still the same length. You may also select the full bit for bit compare option for executable programs or all files on the target disk. I don't think the virus mongers can figure out how to mess with the floppies in your storage box. I use DirBack daily, and I will update all registered copies immediately, at my expense, if there is any indication of a virus aimed specifically at DirBack. Daily maintenance of the duplicate disks is a breeze. You only need to update the disks with directories you know have changed. A few minutes a day will keep your backup disks ready to restore your hard drive on a moments notice. Building your first set of duplicate disks will take some time. Thereafter, the ease in maintaining the set and the virus protection more than makes up for a high speed "backup". If only a few files actually need to be copied, DirBack will keep you very busy changing disks. Most of the How-to's are covered in the following paragraphs. You should have the following DirBack programs and files. It is recommended the programs and files be copied, except for the BAT file, into a directory called DIRBACK. DirBack will create the other files it uses the first time it is executed. DIRBACK.BAT DIRBACK.EXE DIRBACK.DOC DIRDATA.EXE DIRDISK.COM DIRBACK.REG INSTALLING DIRBACK: The basic installation is simple. Make a reserve copy of DirBack and then copy the DirBack files to your hard disk. The first time you execute DirBack you will be asked if it is ok to copy your system files. The copies will be used to verify the integrity of your system each time DirBack is executed. DirBack will also put the time, date, and length of your three primary system files and the DirBack programs in its configuration file. During the process, copies of the DirBack programs will also be placed in the \STASH directory. Thereafter, DirBack will let you know it's checking them before displaying the main menu. The same messages you'll see when you start DirBack on your system the first time will appear to let you know exactly what has happened if any change is detected. DirBack will also entertain you with a new jazz melody each time it is executed while performing the system checks. You can skip the verification by pressing <Esc> after DirBack starts. You may copy the DirBack files into any directory on hard disk or another floppy. The only real requirement is that all of the files associated with the program, except for its BAT file, must be in the same directory. You may activate the program directly, with a BAT file, or from ActMenu. INSTALLING A DIRBACK REVISION: If you are installing an updated version of DirBack the time, date, and size of DIRBACK.EXE will be different. Delete DIRBACK.VRF in the c:\DIRBACK\STASH directory. When you start the revised version, DirBack will make a new copy of itself to use for integrity verification. CONFIGURATION: Select the configuration window by holding down a <Shift> key and pressing the <Tab> key. The window will display the following options: <A>sk before copy: "Disks Only", "Primary Directory", "All Directories". When "Disks Only" is displayed, DirBack will pause and prompt only when an entire directory will not fit on the disk or the disk is full. When "Primary Directory" is displayed, DirBack will chirp and display the options wherever a directory immediately under the root is to be copied. "All Directories" tells DirBack to prompt before starting any new directory. DirBack will not pause unless there are actually files that need to be copied to the directory. NOTE DirBack will always pause and prompt with "New Directory" if a new directory must be created or "Insufficient space" if all of the files to be copied in the current directory will not fit on the target disk. <C>hange sound from: "QUIET", "BEEPS ONLY", or "FULL SOUND" BEEPS ONLY will disable the melody DirBack plays while performing the system file checks. <D>isplay colors: Accesses the color configuration window. Virtually every color DirBack uses may be changed to suit how you want your screen to look. <M>ode: "TIME & DATE" or "ARCHIVE BIT" When the TIME & DATE mode is set, only files that do not exist on the destination disk or with a more current date and time will be copied. If the ARCHIVE BIT mode is set, only files with their archive bit set and files that do not exist on the destination disk will be processed. Files with their archive bit set that also have a time and data match will not be copied. Although DirBack processes the files slightly faster, it is possible to miss updating a file if more than one set of backup disks are being used. Refer also to <C>lear or set archive bits. <V>erify files written to disk: "ON" or "OFF" When the verify mode is set to ON, DOS will read back the file while it is being written to the disk and compare it with the source file. Verify should normally be left on. erform compare for: "NO FILES", "EXE/COM'S", "ALL FILES" When "EXE/COM'S" is displayed, all files with the extension .EXE or .COM will be compared, bit for bit, if the destination file has a matching date and time. "ALL FILES" will do the same for every file. <E>xclude files: Will access the exclude extensions window. The extensions VRF .BAK and .OBJ are the three defaults. You can modify the defaults and list up to ten extensions to be excluded when doing backups or updates. <F>lag file size changes: "ON" or "OFF" The flag mode will compare the source and destination file sizes whenever both have the same date and time. It's a quick, simple way to protect against copying a virus infected file to your backup disk. If a difference in file size is detected, a flashing message will announce the problem. DirBack will wait until you answer the prompt before proceeding. The flag mode slows DirBack down only slightly. <S>ave configuration or just e<X>it: Press <S> to update the configuration file and exit the configuration window. Press <X> or <Esc> to return to the main menu without writing the changes to the configuration file. Any changes remain active until they are changed again or you exit DirBack. ORGANIZING YOUR HARD DRIVE: Before you start building your first backup set, you may want to reorganize your hard drive. I recommend putting all of the DOS programs, except IO.SYS, MSDOS.SYS and COMMAND.COM which must remain in the root, in a directory called DOS. I also like having all of my batch files in a BATBIN directory. A comfortable path statement in your AUTOEXEC.BAT should look something like the following. Don't put DIRBACK's directory in your path statement. DirBack works best if you change to its directory to execute it. You can also use a BAT file similar to the one furnished with DirBack. PATH=C:\;C:\DOS;C:\BATBIN;C:\UTILITY One of the reasons for organizing your hard disk is to ensure the DOS programs and DirBack are at the top of your directory structure. The sleeve label printed by DirBack for my first backup disk looks like the following: ╔═══════════════════════════════════════════════════╗ ║ Volume: MAIN FILES BYTES ║ ║ C: 5 80,896 ║ ║ ├──ACTMENU 9 139,264 ║ ║ ├──BATBIN 38 38,912 ║ ║ │ └──WORKERS 23 63,488 ║ ║ ├──DIRBACK 14 217,088 ║ ║ │ └──STASH 6 262,144 ║ ║ ├──DOS 25 297,984 ║ ║ ║ ╚═══════════════════════════════════════════════════╝ BACKING UP THE FIRST TIME: DirBack will do most of the work for you. The result will be a set of disks that contains your entire hard disk, just the way you like it, organized in alphabetical order by directory. Any size or combination of disks may be used. You can rearrange, add disks, use existing disks, or remove disks from the set without having to start from scratch. If you already have reserve disks that match directories on your hard drive, you can save some time and disks. When DirBack prompts for the appropriate directory, place the reserve disk in the drive instead of a blank disk and let DirBack update it. If no files need to be copied, DirBack will step through it quickly and prompt for the next directory. 1. After starting DirBack, place the first disk in drive A. Press <S> to select the <S>ource drive and press the letter for your hard drive. 2. Press <D> and then <A> to select the <D>estination drive. If you have two floppy drives you can also elect to use the <A>lternate drive and switch back and forth between them. The disks do not have to be formatted in advance. DirBack will automatically prompt if a disk needs formatting or you can interrupt the operation at any time and select the <F>ormat option. 3. If the disk in drive A is not a bootable system disk, press <F> to format the disk. When prompted, answer <Y>es in install the system files. To restore your hard drive, you must have a bootable disk for drive A with DirBack and the appropriate DOS files. Only the first disk needs to be a bootable system disk. 4. Select backing up your <E>ntire hard drive by pressing <E>. Dirback will load the complete directory structure for your hard drive and display it on the screen. You can use the cursor keys to scan up and down through the list and delete any directories from the list you do not want backed up with <T>ag or the <Delete> key. 5. When you are ready, press the <Backspace> key to start the backup. DirBack will start copying the files. 6. Whenever a complete directory won't fit on the current disk, DirBack will chirp and give you a set of options. This is primarily to give you the option of starting the directory on a new disk. Press <C> to <C>ontinue and start copying the directory to the present disk. Press <N> for <N>ew disk, after replacing the disk in the drive. If you want to skip a directory, select <J>ump. Press <A> to <A>bort and go back to the main menu prompt. 7. You may also select the option from the configuration window to ask before copying primary directories or all directories. Thereafter, when the condition exists, DirBack will chirp and display the same options described in Step 6. If it's ok to split the directory, press <C> for <C>ontine or replace the disk and press <N> for <N>ew disk. If you are using both floppy drives, you can press <S> to <S>witch back and forth between the drives. NOTE When you remove the disks from the drive, mark the label with the directory or directories DirBack has copied onto the disk. 8. Continue feeding disks into the drives and answering the prompts until your entire hard drive has been copied. Don't worry about numbering the disks. You may want to add disks later. Your best reference is to mark each disk with the names of the directories it contains. 9. When DirBack beeps and announces the backup is complete, put the second disk back into drive A. Now we're going to cover what most high speed backup programs don't mention. Setting up the disks so you can put the files back on the hard disk when everything goes wrong. 10. Press <S> to select the <S>ource drive again. Then, press <C> or the letter for your hard drive. 11. Press for pdate. Then, press the letter for the drive containing the second floppy you used to copy the hard drive. DirBack will collect the directory structure from the floppy and display it on the screen. Answer the prompt to copy the root with <Y>es. This is to make a second copy of your AUTOEXEC.BAT and CONFIG.SYS files. 12. DirBack will copy the root files and then whip through the rest of the disk. When DirBack beeps and reports it is done, remove the second floppy and put the first floppy of the backup set in the drive. 13. Press <Esc> to exit DirBack. Use your favorite text editor to modify the AUTOEXEC.BAT and CONFIG.SYS files so you can boot up on the A drive without accessing the hard drive. NOTE If you are using 356K (Double Density) floppies, you may need to reorganize the first two disks. Or better yet, create another disk with just DOS and the basic DirBack files for your boot disk. If you need more space you can delete some of the DOS files that won't be needed until later. Make sure the full set is on one of the other disks. 14. Delete the DIRBACK.CFG file so DirBack will not use the hard drive. Try it out a couple of times to make sure you can boot up and execute DirBack. Press <Esc> right after starting DirBack to skip copying and verifying the SYSTEM files and answer the question to create a new configuration file with <N>o. 15. When the backup boot disk works, use ATTRIB.COM, Norton Commander, XTPRO, or your favorite to set the AUTOEXEC.BAT and CONFIG.SYS files to "Read Only". This will keep DirBack from replacing the edited files the next time you update the disk. The first disk is now ready to use, if you need it, and you can take it out of the drive. 16. Put the second disk, with the hard disk version of your AUTOEXEC.BAT and CONFIG.SYS files, back in the floppy drive. 17. Retrieve the AUTOEXEC.BAT and CONFIG.SYS files, one at a time, into your favorite text editor and save them back to the floppy. It's important to ensure the time entries for these files are newer than those on the first disk. Otherwise DirBack will not copy them to the hard drive and replace the ones set up for the boot floppy. Remember to use the second disk to back up AUTOEXEC.BAT and CONFIG.SYS if you change them. That completes setting up your backup set. Now if you want to see how easy it will be to maintain. Go back to Step 1 and run the set through again without the format and editing steps. RESTORING THE HARD DRIVE: I won't go into removing and replacing the hard disk (if the worst happens) or the hard disk formatting procedures. If you set up your disks as described above, DirBack makes a simple process of restoring all your files to the hard disk. It should only take about an hour of your time to restore a full 20 MB hard drive. NOTE Don't forget to select system (/S) when reformatting your hard drive. 1. Put the bootable disk you prepared in drive A and boot the system. 2. Change to DirBack's directory and execute DirBack. 3. Select drive A as the <S>ource drive and the hard drive as the <D>estination. 4. Select <E>ntire floppy. DirBack will load the directory structure and display it on the screen. Press <Backspace> and answer the prompts with <C>ontinue to start the restore process. 5. When the first disk is copied, press <Esc> to exit DirBack. Enter "C:" and "CD\DIRBACK". Then, "DIRBACK" to start DirBack on the hard disk. 6. Once you're working on the hard disk, things get easier. Insert the second floppy in drive A. Select it as the <S>ource and press <E> for <E>ntire disk. When the directory is displayed, press <Backspace>. 7. When the disk is copied, remove it from the drive. Your hard disk should now boot the way it used to. Exit DirBack and boot your computer. 8. Restart DirBack and transfer the rest of the disks to your hard drive. UPDATING A DISK: When DirBack is to pdate a disk, each file is checked to see if it already exists on the target disk. If the file already exists and has the same time and date, or the extension matches one in the exclusion file, DirBack will not copy the file. If the archive mode is active DirBack will not copy files with the archive bit cleared unless they do not exist on the destination disk. If DirBack is supposed to ask before starting a directory it will then chirp and display the options. 1. To start an update, press <S> for <S>ource drive and answer the prompt by pressing the key for the drive to copy the files from. 2. Select <D>estination to set the drive with the disk to be updated. You can copy files from floppy to floppy, hard disk to floppy, or floppy to hard disk. 3. DirBack will log the directory structure for the destination disk and display it. You can use the cursor keys to scan the list. Delete any directory you do not want to copy with <T>ag or the <Delete> key. 4. When you are ready, press the <Backspace> key to start the copy/update process. DirBack will copy only newer or missing files to the target disk. You can press <Esc> to stop at any time. When DirBack finishes the file it is working on, the main menu prompt will return. 5. If there is not enough room, or DirBack is supposed to ask before starting a directory, DirBack will chirp and display the following options: <A>bort: Exits the update process and returns the main menu prompt. Any directories that have not been completed will remain displayed and the <Backspace> key will restart the process with the directory at the top of the list. NOTE You must have a disk in the drive before you press the key for any of the following prompts. If the disk drive is not ready, DirBack assumes you need to format a disk and returns to the main menu prompt. <J>ump: Skips the highlighted directory and will continue with the directory below it. Any directories that are jumped will remain displayed and can be activated again after returning to the main menu prompt with the <Backspace> key. <C>ontinue: Will start copying the files DirBack has currently in its list. This option is primarily intended for use when you are going to continue using the disk already in the drive. If you put a new disk in the drive, use <N>ew disk. <S>witch Disks: Allows alternating between two destination drives. While you are backing up, updating, or restoring your hard disk, you can switch back and forth between the A drive and the B drive. This means you can change the disk in one drive while DirBack is copying files to the other. The drive displayed after "Used" must have a disk ready when you press <Backspace>. <N>ew Disk: If DirBack stops because the disk is full, there is not enough room for an entire directory, or for a new directory and you put another disk in the drive. Press <N> and DirBack will check to see if more of the files in its list are already on the new disk before copying them. If DirBack is supposed to ask before starting a new directory, DirBack will chirp again and you should select the <C>ontinue option. MATCHING A DISK: Having DirBack <M>atch a disk works the same as pdate except only files that exist on the destination disk will be copied. SPLITTING A DIRECTORY: If an entire directory will not fit on a single disk, press <C>ontinue when prompted with "insufficient space". When DirBack prompts with "Disk Full!" change disks and select <N>ew disk. Use the same procedure when creating a backup disk or updating. When updating a disk, this ensures DirBack will update any files already on the current disk before proceeding to the next disk. Occasionally a file will get duplicated on the second disk but it will not interfere with restoring your hard disk. Any old file will be replaced with the most current version and older files will never be written on top of newer files. DRIVE SELECTION: <S>ource disk drive: Allows selection of the SOURCE drive. <D>estination drive: Allows selection of the TARGET drive. <A>lternate w/drive: Allows selection of an ALTERNATE drive that can be activated with <S>witch. DIRECTORY MODES: <Q>uick start: Loads the quick configuration file for the selected source drive. Each disk drive can have its own quick start file which includes the directory displayed and the selected configuration modes if <Q>uick is selected when <W>riting a configuration file. <E>ntire disk: Logs the complete directory structure for the source drive. <T>ag directories: The <T>ag key or the <Delete> key will remove the high- lighted directory from the listing on the screen. <M>atch disk: Will log the directory structure for the destination disk selected. When the <Backspace> key is pressed, only files that match those on the target disk will be copied. This is to simplify copying only specific files contained in a large directory on the hard drive. rint: Will output the current directory listing to a printer. It will print just about the way you see it on the screen. If your printer does not print the upper 128 ASCII characters you may want to use a utility that will convert them to codes your printer can use. Your printer manual may explain how to set the printer for IBM Character Set 2. After building your backup set, you can use pdate or <M>atch to log each directory and use rint to create a label you can attach to the sleeve. pdate disk: Will log the directory structure for the destination disk selected. When <Backspace> is pressed, all files in the matching directories on the source drive will be checked and copied to the target disk if a newer version exists or they have not been copied yet. <G>et directory: Allows entry of a specific directory for transfer. If a directory name is already highlighted on the screen, its full path will be displayed for edit. STATUS DISPLAY: Directories: #### Total Files: #### Bytes \\ ##,###,### Used \\ ##,###,### Avail=##,###,### Directories: Will show the number of directories currently logged for updating. Total Files: Initially displays the number of files on the source drive which will be checked. When DirBack chirps and indicates there is insufficient room or a new directory, the number of files DirBack is going to copy is displayed. The total number of files is updated after each directory is completed. Bytes: Displays the source drive and how many bytes are contained in the directories displayed. This entry changes to "Copy" during the backup process and displays the size of the directory and then the files being copied. Used: Displays the destination drive and how much of the disk has already been used. Avail: Will display how much space is available on the destination drive. Used and Avail are updated after each file is copied. SPECIAL FUNCTIONS: <BackSpace>: Activates the displayed directories for backup. <F>ormat or clear floppy: The option for a fast deletion of all files and directories or formatting is available. After formatting, you may elect to make the disk a bootable system disk. <C>lear or Set all archive bits: When the "ARCHIVE BIT" mode is set, this option may be used to set or clear the archive bits for all of the files contained in the directories displayed on the screen. <L>oad backup definition file: DirBack will maintain up to ten numbered configuration files. You can also save a <Q>uick start file for each disk drive. Each DIRBACK_.CFG file retains the directory structure displayed when you write the file and all of the current transfer modes. You may <L>oad a configuration file by pressing its number. When <L>oad or <W>rite is selected a pop up window will display the ten numbered definition files. You can select the numbers with the cursor keys and press <E> for edit to enter a title or description. Pressing <Enter> will load or write the highlighted file. <O>perating system: Pressing the <O> key will access DOS from inside DirBack. You will be returned to the DOS command level where you can execute DOS commands or another program. When you are finished, type EXIT and press <Enter> to return to DirBack. Any directories you were working on will still be displayed and you can continue where you left off. CAUTION Do not execute Terminate and Stay Resident (TSR) programs after exiting DirBack with <O>. DOS will put them above DirBack and you will have to re-boot to restore your system. Activate any TSR's at the DOS prompt before starting DirBack. <W>rite definition setup file: You may save a quick configuration file by pressing <Q> or a numbered configuration file by pressing a number. Refer to <L>oad for details. <SHIFT-TAB> for configuration: Accesses the configuration window described under CONFIGURATION above. USING DIRDATA.EXE INDEPENDENTLY: The DIRDATA.EXE program will display a four column directory listing in alpha- betical order. The options allow a variety of uses including a directory listing for an entire disk. DirBack uses this program for logging directories and it must be in the same directory as DirBack. The DirBack support program DIRDATA.EXE may be used as a stand-alone program using the following syntax and options. The program was originally released into the public domain as D.EXE and is not to be sold. The registration fee requested is solely for the use of the DirBack program. Syntax: DIRDATA [-ABDLNRT1] [d:\path] DIRDATA OPTIONS: A = Display all files, including hidden, system and volume labels B = Causes a descending sort instead of an ascending sort D = Display only subdirectory names L = Displays a file and its attributes as: a = Archive indicator. File written since last backup d = This file is a sub-directory h = File is normally hidden r = File is marked read-only s = File is marked as a system file N = Display all files NOT matching <path name> R = Display from current directory recursively T = Sort files by time last written 1 = Display in 1 column USING DIRDISK.COM INDEPENDENTLY: The DIRDISK.COM program will prepare a disk for re-use by formatting it quickly, optionally with a new volume label. Full format modes are also available. DirBack uses this program to perform the disk erase and format functions and it must be in same directory as DirBack. The DirBack support program DIRDISK.COM may also be used as a stand-alone program with the following syntax and options. The program was originally released into the public domain as QDR.COM and is not to be sold. The registration fee requested is solely for the use of the DirBack program. Syntax: DIRDISK d:[label] [/F][/N][/V][/B][/Q][/1][/2][/3][/4][/8] The drive (d:) parameter is required to supply the drive letter. Fixed disks cannot be formatted. You may supply a DOS compatible volume label (up to 11 characters) immediately following the drive letter. For example: DIRDISK b:scratch You may supply the /F option to force a full format of all tracks. The /1, /2, /3, /4, and /8 options apply to a full format, and specify the disk type. Bad clusters remain marked as bad unless a full format is used, then clusters are marked as unusable if they cannot be formatted. Use the /V (verbose) option to display the cluster numbers that are marked as not usable. The /N option suppresses the "Press ENTER to continue" prompt. Otherwise, press the enter key to reformat the disk, or the Escape key to cancel. DIRDISK OPTIONS: /F - forced full format; uses DOS to format and verify each track. /1 - forces single sided format, SSSD/8 or SSSD/9, on 360 KB drives. /2 - forces DSHD format on 1440 KB capacity drives /3 - forces DSQD format on 720 KB capacity drives /4 - forces DSDD format on 1.2 MB capacity drives /8 - forces 8-sector format; SSSD/8 or DSDD/8, on 360 KB drives /N - no prompt; skips the "Press ENTER" message and reply /V - verbose messages; displays a message for each cluster that is marked as unusable /B - use disk BIOS routines only for formatting; if omitted, the DOS routines used for formatting are determined by the version of DOS in use. /Q - quick format without verification or bad track marking. If the target disk has bad spots, write errors may result. This option is NOT recommended for formatting new diskettes. Please let me know if you have any problems with DirBack. It's very important to me to have my programs behave properly. I have gone to great lengths to ensure DirBack does only what it is supposed to. However, I have no control over modifications or differences between the equipment built by the various manufacturers and cannot accept responsibility for inconsequential damage. I will replace, free of charge, disks and software received directly from me if the disk or software is faulty. My technical support is available for registered users anytime, day or night. Thanks, Chris P.S. I'll send you a free copy of all of my games and programs if you snag a virus zeroing in on DirBack or DirBack can't catch. CAUTION If you are executing DirBack on the original distribution diskette, please answer the question to create a new configuration file with <N>o. The disk does not have enough space for DirBack to create all of its directory for virus checks. [ If you are using BROWSE, press <Esc> to exit ]
