Introduction -------------- If you have used this program before try to make the effort to read this doc again. Some useful info is updated, not listed in previous versions. Read also 'fmirr15.doc' for changes ! 1.1. Legal ------- Type : - MAILWARE (as of V1.5 only send email for bug reports) Terms : - no modifications to any file in this archive - add no additional files to this archive - use this program longer than 30 days, then you should reward the author with a postcard/letter/email, hence the term mailware - author can not be held responsible for data loss, the program has been tested and the behaviour has been described below - any commercial distribution is prohibited (except on Aminet). 1.2. What it does -------------- 'FBack' is a file copy tool. It will check the archive bit of files and copy them if the archive bit is not set. After copying it will add the archive bit. It can be used to perform a 'Daily' backup of changed files. As an option you can run the program in GUI mode, this will open up a window which keeps up with the process. When processing has finished the window will remain open until you close it with the close gadget. Unless you specify NOWAIT, then the window is closed immediately after processing. In GUI mode the 'Current' gadget displays the files it is scanning. In CLI mode it merely reports the directories it is scanning, but the files being backed up are listed. On request of some users a CLONE option has been added, meaning the date/time is preserved on the backup. The filenotes are copied by default, specifying the NOCOMMENT option will suppress this. The program includes a batch mode, paths and options are then specified with a configuration file. Several entries are allowed. Some extra statistics, the estimated processor time (for now only in second(s)) are displayed. New features: - PRI option (also in batch mode) - BUF option now supported in batch mode - report on Kilobytes processed - report on packed bytes gained/lost - language support - executable for 68020/060 'FMirror' is included. Its purpose is to delete files which no longer exist in the original directory, thus creating a mirror. It also deletes empty (obsolete) directories from the backup, cleaning up etc. There has been a remark concerning the mirror concept in combination with the pack mode, if you take it word for word, issuing PACK is no EXACT mirror (jeezes!). Mirroring is portrayed in this implementation as following concept: you have a copy (normal or packed) on the backup volume of what is on your source path (Comprendo!). 1.3. Requirements -------------- Properly installed Amiga ROM 2.1+. Needs XPK library when using PACK option. GUI window uses standard GADTOOLS library. May need Argue (V1.3+) to use FBackGUI, FMirrorGUI. [Can be found in the "CyberQT" archive on Aminet] 1.4. Contact address ----------------- For mail/information/problems/gifts/bugs etc. write to the address below, state version & add postage for reply: Visionary Software tav. Chris De Maeyer Norbertijnenstraat 4 B-2040 BELGIUM EUROPE Internet :cdemaeyer1@mmm.com Alternate:ceppe@geocities.com Homepage :http://www.geocities.com/siliconValley/peaks/8452 http://www.crosswinds.com/antwerp/~visionary 1.5. Development info ------------------ Sources were written in C and compiled using SAS/C V6.58. All file I/O has been coded using standard system library functions (V38+). 1.6. Versions ---------- The actual version can be determined by typing 'version fback' in a CLI window. It is recommended to always upgrade to the latest version. V0.9 TEST RELEASE - first internal test version. V1.0 FIRST PUBLIC RELEASE - cleaned up code - adapt stack size + compile with stackextend, optimize - first public release. V1.1 MAJOR UPDATE - added file report after processing - shortened output strings + reformat - changed ExamineDir() flow, performs better with patterns - message to indicate NOCOPY mode - fixed error in document (FROM/A & TO/A examples). V1.1a MINOR UPDATE - changed some buffer sizes for speed, copybuffer = 16Kb. V1.2 MAJOR UPDATE - added packing mode - added XPK packer/unpacker - added date in version string. V1.2a MINOR UPDATE - updated some internal values - added Argue GUI - added BUF option. V1.2b MINOR UPDATE - added FORCE option - changed some displayed strings. V1.2c MINOR UPDATE - replaced SAS pattern match function with 'dos.library' function MatchPatternNoCase() - fixed pattern matching. V1.3 MAJOR UPDATE - archive bits are also set on destination (Oops!) - added GUI window option - added NOWAIT option - added CLONE option, to keep date on destination. V1.3a MINOR UPDATE - filenotes of files are copied now - added NOCOMMENT option - code generation with SAS/C 6.58. V1.4 MAJOR UPDATE - fixed traversing the directory tree - HandleIDCMP() uses Wait() now - added estimated processor time (and total time) report - changed output attributes of some strings - FROM, TO paths are checked now - filenotes of directories are copied now - added configuration file mode (batch). V1.4a MINOR UPDATE - added BEFORE/ASOF date possibility Remark: I tested with async I/O functions but these gave a poor result ! Why ? Rather simple to be honest, I can not do/find any other task to do while copy is busy... ASYNC TEST RESULTS ------------------ Mb Buffer Time To Backup --------------------------------- 24 16 Kb 98 seconds 24 64 Kb 68 seconds 1.5 16 Kb 30 seconds (small files) See table with BUF option for reference to normal implemented routines. V1.4b MINOR UPDATE - support for more files - default copy buffer size 32Kb V1.4c MINOR UPDATE - bugfix in file arrays - aborts on CTRL_C in CLI mode V1.5 MAJOR UPDATE - added PRI option, also in batch mode (CFG) - BUF option can now also be specified in batch mode (CFG) - reports Kilobytes backed up/examined (CLI) - reports bytes gained/lost in PACK mode (CLI) - some reformatting of strings - added language support - executable for 68020/060 2. Using it ---------- 2.1. Command line options ---------------------- The program uses standard AmigaDOS command templates, so typing 'FBack ?' will list all the options available. Detail explanation of options: FROM/A - the source path, a AmigaDOS file pattern may be given. fe. BOOT: BOOT:Prefs/ BOOT:S/#?.keyfile As you can see, a volume needs no '/'. However, a directory always needs a '/'. If a volume\directory is entered, only that part will be checked, to include all subdirectories include the 'ALL' switch. fe. FBack BOOT: TO BACKUP: ALL FBack WORK:data/ TO BACKUP:Sys/ PACK=HUFF ALL Fback WORK:data/calc/#?.wk1 TO BACKUP:Wks/ ALL TO/A - the destination path. fe. BACKUP: SQ0:Backup/Workbench/ Same rules as above, a volume needs no '/'. A directory always needs an ending '/'. As you might expect, the 'ALL' switch will create any missing subdirectories in the destination path. NOCOPY/S - this does exactly what it says, when a file has been modified it is normally copied to the backup location. Adding this parameter prevents this and the program will merely report the file. Call it a SIMULATE mode. ALL/S - include subdirectories. QUIET/S - no output messages (shut it up). *NEW* PRI=/K/N - set priority (-100 to 5), in the old days you could use a task manager to do this, now you can simply add it as an option either to speed-up or let it creep in the background. A test result: Fback sys: to backup: all clone 289s Fback sys: to backup: all clone pri=5 206s (Do not pin me on these times, they are dep. on various parameters...) Q: Why I've put in a min. and max. ? A: To avoid problems. As a Amiga guy you should know that setting priorities wrong can give strange results. Fe. program keeps running and doesn't react to input anymore. Eg. console.device runs at priority 5 etc. PACK=/K - enables packer mode, supply preferred packer. In this mode make sure your recovery disk includes the XPK library + some XPK unpacker (fe. xpk [included]) to restore files. fe. PACK=nuke BUF=/K/N - choose the buffer size used for copying, default is 32 Kb. Size limited only by your available RAM (but do not try to use TOO big sizes, 32 Kb will do fine for most users). *********** READ THIS HERE !!! *************** The buffer size is specified in bytes. ********************************************** This table states a test result (on my system!): Mb Buffer Time To Backup ------------------------------------ 24 16 Kb 84 seconds (big files) 24 64 Kb 47 seconds " " 24 128Kb 32 seconds " " 1.5 16 Kb 29 seconds (small files) 1.5 64 Kb 28 seconds " " 1.5 128Kb 28 seconds " " Obviously, the speed increase is optimal while backing up large files and vanishes if little files are processed. FORCE/S - specifying this option will ignore the archive bit, thus copying every file (= full backup). GUI/S - opens GUI showing some statistics, no more CLI output. NOWAIT/S - when using GUI mode, closes the window immediately after processing finishes, otherwise window remains open until you click the close gadget. CLONE/S - clones file date/time to destination. NOCOMMENT/S - specifying this option will instruct FBack NOT to copy the filenotes. CONFIG=/K - run in batch mode, this parameter contains the filename of the configuration file to process. Syntax configuration file (text file): ----------------- cut ---------------------- [FBack] NumberOfPaths = <N> [Paths] SrcPath1 = <source path 1> DstPath1 = <destination path 1> ... SrcPathN = <source path N> DstPathN = <destination path N> [Options] BOptions1 = <fback options for entry 1> MOptions1 = <fmirror options for entry 1> ... BOptionsN = <fback options for entry N> MOptionsN = <fmirror options for entry N> ----------------- cut ---------------------- Example: study "MYBACK.CFG" included in the archive. To start batch mode use a command line like: fback "" "" cfg=myback.cfg or fback "" "" config=whatever NOTE: To detect in which mode (CLI or GUI) FBack will run the first option entry is taken. Thus, specifying GUI in the 1st option entry will trigger GUI mode for all subsequent batch entries. Leaving GUI out of the 1st option entry will run all subsequent entries in CLI mode. NOWAIT is also only interpreted in the 1st option entry. When running batch mode with GUI, the current gadget will display the batch entry it is going to process for a couple of seconds. After the batch entry is done the "Estimated processor time" is displayed. When all batch entries are finished the "Total processor time" will be shown. ********* BATCH MODE CHANGES ************** Now supports BUF= and PRI= options ******************************************* BEFORE=/K This triggers the date selection. Enter the date in DOS format (dd-mmm-yy) meaning this is also localized. For example: 15-okt-97 for Belgian/Dutch users. ASOF=/K Opposite of the previous, will backup files as of the the date given and after it. So,the date given is included in the selection. The return code is either RETURN_OK (0) or RETURN_WARN (5) in all other cases. For some examples look at next section "2.2. Examples". While in CLI mode the program can be interrupted by pressing CTRL-C. Tip: for GUI mode you could send a break with a task manager ! If you have Argue V1.3a you can use the GUI (FBackGUI) version to specify options. NOTE: the logical sequence to run FBack/FMirror is run FBack first, then run FMirror (as you see in the first example below). Some users do it the other way round (the logic escapes me!). 2.2. Examples ---------- This section lists some examples of usage. - Backup changed prefs files: ; Startup-sequence ... FBack sys:prefs/env-archive/ to work:backup/prefs/ ALL FORCE QUIET FMirror work:backup/prefs/ to sys:prefs/env-archive/ ALL QUIET ... - Mirror a disk at startup & create logfile: ; Startup-sequence ... FBack sys: to mirror:boot/ ALL >T:FBack.log FMirror mirror:boot/ to sys: ALL >T:FMirror.log ... - Mirror files before shutdown: .key FLAG .bra { .ket } ; Shutdown script echo "Just a moment, valuable files are checked..." ; if {FLAG} EQ "GFX" FBack work:data/gfx/ to backup:data/gfx/ ALL GUI NOWAIT echo "Gfx data has been saved." endif if {FLAG} EQ "ALL" FBack work:data/ to mirror:data/ ALL GUI NOWAIT FMirror mirror:data/ work:data/ ALL GUI echo "All data has been mirrored." endif ; FBack sys:prefs/ to mirror:prefs/ ALL PACK=BZLW QUIET echo "System preferences have been saved." ; if exists C:Halt echo "It now safe to switch me OFF !" Halt endif - Backup certain files in a range of dates: fback data:texts/ backup: all clone asof=01-feb-97 before=10-feb-97 Will backup the files from 01 february 1997 till 09 february 1997. 3. Appendix ---------- 3.1. Common problems ----------------- Q: It doesn't find its source/backup files ? A: Enter the correct path: see section 2.1 (FROM,TO option). Q: Fback picks up not any file ? A: Did you end the source path with a '/' ? Leaving it out will traverse the entire source drive without touching any file. Call it a side-effect ! Q: When I backup to a JAZ/ZIP drive it takes a long time ! A: Add a large number of disk buffers, eg. 'AddBuffers JAZ5: 2000'. This is not caused by FBack, but due to the way JAZ/ZIP works. 3.2. Error messages ---------------- 'Source/Destination not found' The entered path could not be located. Correct your paths ! 'File not found' The file you typed could not be found. 'Invalid date' Enter the date in ADOS format, thus dd-mmm-yyy. Example: 01-jan-97. 'No xxxxx date' Supply a date with the BEFORE/ASOF keywords. AmigaDOS errors are in format : 'FBack: nnn - message' 3.3. Language support ------------------ From V1.5 onwards the program supports different languages. This initial archive contains a translation for Dutch only. I suppose there are users around willing to make translations of their own. For this purpose a catalog translation source file has been included. Make one and send it to me, then I will generate it and release it as a seperate archive. If you know how to generate a catalog yourself then use the supplied description file, then use the command line: catcomp languages/fback.cd fback.ct catalog fback.catalog copy fback.catalog locale:catalogs/<language> Here is the path to the files in the distribution: Catalog description file -> languages/fback.cd Catalog translation file -> languages/fback.ct 3.4. The future ------------ Any suggestions/motivations/gifts from you are welcome ! Thanks to all guys & dolls sending me real MAIL. It is because of YOU this program keeps getting better and better... Things I wish to examine myself: - multi-volume target - smarter pack mode (if lost bytes, then don't pack) 3.5. About me ---------- Well, I'm working as a "Technical Analist" for a multinational company. My main responsibilities are "Implementing and supporting the WINDOWS NT LAN/WAN environment" (shame on me !). It's only for the money... give me a break ?? (If my bosses read this -> I'm only sucking up the great Amiga community !). At home I have a Amiga 4000T (68060/50/PPC, 80Mb Fast, 1GB SCSI HD, 2GB IDE HD, Syquest 105, a JAZ (my backup device!), VLab digitizer, Cybervision 64, Y/C genlock, 2 VCR's, etc). Which I primarily use for desktop video, animations, LightWaving, programming [and making backups (I detect a bit of sarcasm here !)]. I started my Amiga carrier on a A500, upgraded to A2000 and later a 68020 accelerator card (somewhere in the cellar now). Gosh, I've got a PPC 604e (200Mhz) now ! Anyway, hope you can use the program (I do !).
