ΓòÉΓòÉΓòÉ 2. Features ΓòÉΓòÉΓòÉ
Features include the following:
o Scheduled Backups
o Compression
o Verify
o Media Format
o Supported Tape Drives.
o Tape Formatting.
ΓòÉΓòÉΓòÉ 2.1. Scheduled Backups ΓòÉΓòÉΓòÉ
Unattended backups may be performed with BackMaster's easy to use unattended
backup feature. Simply select the files you wish to backup, enter the date and
time for the unattended backup to start, and BackMaster takes care of the rest.
ΓòÉΓòÉΓòÉ 2.2. Compression ΓòÉΓòÉΓòÉ
With compression, BackMaster can double the amount of information stored on a
tape. On faster computers, compression can actually increase performance
during the backup by increasing the density of the data going to the tape.
ΓòÉΓòÉΓòÉ 2.3. Verify ΓòÉΓòÉΓòÉ
BackMaster can compare the data on the tape with the data on the fixed drive to
ensure the integrity of the backup. Verify compares the following file
attributes: date, time, size, and content.
ΓòÉΓòÉΓòÉ 2.4. Media Format ΓòÉΓòÉΓòÉ
QIC Compatible Format: BackMaster uses the QIC-500 logical format. QIC-500 is
a superset of the popular QIC-40/80 format and provides compatibility with your
DOS QIC-40/80 tapes. QIC-500 backup volumes can also co-exist with QIC-40/80
backup volumes on the same QIC-40/80 tape.
ΓòÉΓòÉΓòÉ 2.5. Supported Tape Drives ΓòÉΓòÉΓòÉ
BackMaster is compatible with the following tape drives.
o Archive XL-80
o Colorado QIC 40 Tape Drive (Jumbo 120)
o Colorado QIC 80 Tape Drive (Jumbo 250)
o Conner 250
o Iomega Tape 250
o Mountain Filesafe 4000
o Mountain Filesafe 8000
o Summit SE120
o Summit SE250
o Generic QIC 40 Tape Drive (as 2nd device)
o Generic QIC 80 Tape Drive (as 2nd device)
o Tape Drive using AB-10 controller
Note: Some companies resell drives as OEM or Generic drives. These drives
often work correctly if selected as the original manufacturers name. Ask your
reseller for the original manufacturer name, or call MSR Development Technical
Support for assistance.
See the README file on your BackMaster installation diskette for additional
drive types. README is an ASCII text file and may be viewed with any text
editor.
ΓòÉΓòÉΓòÉ 2.6. Tape Formatting ΓòÉΓòÉΓòÉ
Formatting a tape is the process of preparing a new tape for data or refreshing
a tape that has been used before. If the tape has been used by a different
system, bulk erasing and a fresh format often improves performance. It is
important to remember that any data currently on a tape will be lost after
formatting.
See the hardware reference that came with your tape drive for a list of
recommended tape cartridges.
When using a DC2120 tape, the typical format time is 60 minutes for QIC 40 and
120 minutes for QIC 80. The format time includes both the format pass and the
verify pass. You can avoid this loss of time by purchasing preformatted tapes.
Preformatted tapes for the QIC-40 drives must be compatible with the THETAMAT
format. Preformatted tapes for the QIC-80 drives must be compatible with the
XIMAT format.
BackMaster requires that all media be formatted prior to backup operations. It
will be necessary to format all tapes before starting The Backup Process.
ΓòÉΓòÉΓòÉ 3. Installing BackMaster ΓòÉΓòÉΓòÉ
1. Insert the BackMaster installation diskette into the floppy drive.
2. From the OS/2 system prompt, change to the drive containing the BackMaster
installation diskette and type: BMINST. For example, if the diskette is
in drive A:
[ A:\ ] BMINST (Enter)
After the main installation screen appears, examine the letter of the drive
from which BackMaster will be installed and the path to which BackMaster will
be copied. Make sure that both are correct.
The check boxes at the bottom of the screen function as follows: BackMaster
folder
Install Files
BMINST will copy all necessary files to the destination directory.
Update System Configuration
BMINST will modify CONFIG.SYS to put the DLL and program files in
the path as well as add the driver FTDVR.SYS
Create Desktop Object
BMINST will create a BackMaster icon on the presentation manager
desktop.
Press OK to start the installation procedure.
Note: The system must be Shut Down and Rebooted for the changes made in the
CONFIG.SYS to take effect.
BackMaster should now be successfully installed on your system.
ΓòÉΓòÉΓòÉ 4. Navigating BackMaster ΓòÉΓòÉΓòÉ
BackMaster follows standard OS/2 conventions in its use of a mouse and keyboard
to navigate the OS/2 environment. The left mouse button is used to select
items such as menus, options, and configuration settings. The right mouse
button is used to select and de-select folders. Keyboard equivalents are:
CTRL S Select folder
CTRL D Deselect folder
+ Expand one branch
CTRL + Expand all
- Collapse one branch
CTRL Collapse all
CTRL P Progress window
CTRL C Configuration window
CTRL M Message log window

details on using OS/2 Help.
ΓòÉΓòÉΓòÉ 5. Configuration ΓòÉΓòÉΓòÉ
Before BackMaster can be used it must be configured for your individual system.
A variety of options allows BackMaster to be configured for specific needs.
See also: Configuring BackMaster
ΓòÉΓòÉΓòÉ 5.1. Configuring BackMaster ΓòÉΓòÉΓòÉ
Configuration is performed on startup after a new install or by your selection
of Configuration from the the options menu If you have not yet installed
BackMaster, please refer to the installation section for assistance.
The configuration options screen is located under the options menu. It is
divided into four groups. Each group has several items. The four groups are:
Device group
Backup Device, Compress, Enable Time Critical
Files group
Forced Read List, Overwrite Options
Unattended group
Time/Date, Enable Unattended
Errors group
Locked Retry, Error Retry, Prompt, Log
ΓòÉΓòÉΓòÉ 5.1.1. Device group ΓòÉΓòÉΓòÉ
The Device group has three items: Backup Device, Compression, and Enable Time
Critical.
Under the Backup Device dialog box is a list of supported backup devices. The
current available choices are:
o Archive XL-80
o Colorado QIC 40 Tape Drive (Jumbo 120)
o Colorado QIC 80 Tape Drive (Jumbo 250)
o Conner 250
o Iomega Tape 250

o Mountain Filesafe 8000
o Summit SE120
o Summit SE250
o Generic QIC 40 Tape Drive (as 2nd device)
o Generic QIC 80 Tape Drive (as 2nd device)
o Tape Drive using AB-10 controller
Note: Some companies resell drives as OEM or Generic drives. These drives
often work correctly if selected as the original manufacturers name. Ask your
reseller for the original manufacturer name, or call MSR Development Tech
Support for assistance.
Note: See the README file on your BackMaster diskette for additional drive
types.
Select your installed hardware from the backup device list. Your choice will
appear in the backup device field.
The Compression control allows maximization of tape capacity. Compression
will increase throughput on faster machines.
The Enable Time Critical check box, when selected, gives BackMaster higher
priority than other processes. This option should be checked if BackMaster is
used in a heavy workload environment. Using Enable Time Critical will improve
reliability but may slow down other processes.
ΓòÉΓòÉΓòÉ 5.1.2. Files Group ΓòÉΓòÉΓòÉ
The Files group has two items: The Forced Read List and Overwrite control.
The Forced Read option enables BackMaster to read files that are locked. You
may select, via complete filenames or wildcards, files which are to be read
even if locked. The filenames or wildcards may be added or deleted from the
list with this control.
When restoring files, BackMaster enables you to selectively overwrite or skip
existing files. The Overwrite options include:
Yes Overwrite all existing files.
No Do not overwrite any existing files.
Prompt Allows you to decide if each file will be overwritten.
If Newer Overwrite files if the restored file is newer.
ΓòÉΓòÉΓòÉ 5.1.3. Unattended Group ΓòÉΓòÉΓòÉ
The Unattended group has controls for the unattended backup option.
Unattended backups can be made to tape by activating the unattended option of
BackMaster. This is accomplished by setting the time and date that the backup
is to be made and then selecting Enable Unattended. During unattended backups,
prompting is defaulted to "Off".
For unattended backups to work correctly, the files/folders to be backed-up
must be selected, Enable Unattended must be checked, and BackMaster must be
running.
ΓòÉΓòÉΓòÉ 5.1.4. Errors group ΓòÉΓòÉΓòÉ
The Errors group contains four items: Locked Retry, Error Retry, Prompt, and
Log.
The Locked Retry control specifies how many times BackMaster will attempt to
read a locked file that is not in the Forced Read List.
The Errors Retry control allows you to specify how many times to retry a file
in the event of an error. The Prompt check box activates user prompting during
tape operations. This is disabled for unattended operation.
The Log check box enables logging to the Message Log and BACKMAST.LOG file.
This log file can be viewed with the Message Log option under the options menu.
Note: With the Prompt and Log boxes unchecked, you will have no record of tape
operations.

ΓòÉΓòÉΓòÉ 8. The Backup Process ΓòÉΓòÉΓòÉ
BackMaster makes your backup, restore, and verify tasks simple. See the
section on Backing Up Files.
ΓòÉΓòÉΓòÉ 8.1. Backing Up Files ΓòÉΓòÉΓòÉ
The following steps will guide you through The Backup Process:
1. Double-click the BackMaster The Main Selection Window will appear.
2. Make sure that the tape is NOT write protected by sliding the write
protect tab on the tape to the "Record" position. Insert your backup tape
and verify that it is ready to receive your new backup data with the
Return Tape Information option in the Utilities menu (the Utilities menu
is under Options).
3. Under the Backup menu, click on Select files.
4. If your system has more than one fixed drive, a drive selection box will
appear. Select the drive from which files will be backed up.
Note: Only one source drive may be selected at a time.
5. You will be prompted for the name of a backup volume and an optional
password. Remember that a password protected volume cannot be restored if
the password is lost.
6. The directory tree for that drive will appear in the main BackMaster
window. Select files to be backed up as described later under Selecting
Files.
7. Make sure the tape is in the drive. If more than one tape is necessary,
BackMaster will prompt for additional tapes as needed.
Note: Be sure that you have enough formatted tapes available since tapes
cannot be formatted during a backup.
8. After selecting files, click on the Start Backup menu option under the
Backup menu.
ΓòÉΓòÉΓòÉ 8.2. Selecting Files to Back Up ΓòÉΓòÉΓòÉ
If you have ever used the OS/2 drive folder or have manipulated files under the
OS/2 Presentation Manager, you already know how to select files in BackMaster.
BackMaster provides a simple, easy-to-use interface that takes all the work out
of selecting files. Just point and click on a file and it is selected;
selecting an entire drive is as easy as selecting a single file.
o Expanding and Collapsing Directory Tree Branches
o Subdirectory Inclusion
o Menu Options
o File Filters and Incremental Backup
ΓòÉΓòÉΓòÉ 8.2.1. Expanding and Collapsing Directory Tree Branches ΓòÉΓòÉΓòÉ
Each folder containing subdirectories is noted on the directory tree display by
an expand [+] mark to the left of the folder. To expand the subdirectory
branches, simply click the [+] mark. This process may be repeated for as many
subdirectory branches that exist. To collapse these branches, simply click on
the collapse [-] mark that now replaces the expand [+] mark in the directory
tree display.
ΓòÉΓòÉΓòÉ 8.2.2. Subdirectory Inclusion ΓòÉΓòÉΓòÉ
When a folder is fully selected (indicated by a solid red check mark), all of
its subfolders are selected. To select an entire drive, fully select the root
folder.
ΓòÉΓòÉΓòÉ 8.2.3. Menu Options ΓòÉΓòÉΓòÉ
There are two menus of which you should be aware when selecting files. The
first menu is the Tree menu on the directory tree window. The second is the
popup menu which is accessed by clicking on a folder with the right mouse
button. Both the Tree menu and the popup menu have several useful options
which are described below. There are keyboard equivalents for most of the
options described. Refer to the Navigating BackMaster section for a complete
list.
o Select Folder enables you to select all files in the currently highlighted
folder.
o Deselect Folder deselects the currently highlighted folder.
o Expand Branch expands one sublevel of the highlighted folder.
o Expand All expands the entire directory tree.
o Collapse Branch collapses one sublevel of the currently highlighted folder.
o Collapse All collapses the entire directory tree.
These basic functions are duplicated when you click on a folder with the right
mouse button to display the popup menu.
Note: The file filters are unique to that folder and its subfolders.
When the popup menu is displayed, the default menu item is either Select
Folder or Deselect Folder. The default item is determined by the file
selection status of the folder for which the popup menu is displayed. If the
folder is fully selected, the Deselect Folder menu item is the default;
otherwise, the Select Folder menu item is the default. Since the mouse is
moved to a position directly over the default menu item, you can effectively
toggle the selection status of a folder by double-clicking with the right
mouse button.
When a file folder is double clicked with the left mouse button, a file list
window of that folder appears. From this file list window, you can then
select or deselect files by clicking them with the left mouse button.
Contained within the file list window is a Folder menu allowing the following
choices of how the file list window should appear:
o Details View offers a comprehensive list of files and attributes.
o Icon View displays all files in the folder as icons.
o Text View lists files by name only.
As files are selected for backup, check mark indicators appear on the file
folders in the directory tree. If all files contained in a folder are
selected, a solid red check mark appears. If specific files within a folder
are selected, a partial check mark appears. If no files within a folder are
selected, no mark will appear.
ΓòÉΓòÉΓòÉ 8.3. File Filters and Incremental Backup ΓòÉΓòÉΓòÉ
Use our selective file filter or incremental backup features to select only the
files you want. Both can be applied to an entire drive or specific folders.
The Global File Filters Dialog enables you to provide BackMaster with a list of
wildcards and a date filter applicable to the entire backup set. Wildcards may
include the "*" and "?" characters, but a path cannot be specified.
The Incremental check box automatically selects files that have not been backed
up. Any file that has changed since the last backup will be included in the
backup set. After a successful backup, each file backed up will have its
archive attribute cleared to indicate that it was backed up.
ΓòÉΓòÉΓòÉ 9. The Restore Process ΓòÉΓòÉΓòÉ
You may use BackMaster to restore backed up data from tape, restore an entire
volume, or restore specific files. The file selection process for Restore is
identical to Backup.
o Restoring withBackMaster describes how to use BackMaster to recover an
entire drive or specific files. You will need to be able to boot OS/2 in
order to use this procedure.
o Text Based Restore Utility describes how to use BackMaster's minimal
installation restore routine, BMREST, to restore to a system that does not
have the Presentation Manager (PM) version of BackMaster installed. BMREST
is the utility to use if you are unable to boot OS/2 from a fixed disk.
ΓòÉΓòÉΓòÉ 9.1. Restoring With BackMaster ΓòÉΓòÉΓòÉ
The following steps will guide you through The Restore Process:
1. Double-click the BackMaster
2. Insert the tape containing the files to be restored.
3. Under the Restore menu, click on Select Files.
4. If your system has more that one fixed drive, a drive selection box will
appear. Select the drive to which files will be restored.
5. A list of tape volumes will be displayed. Choose the tape volume to be
restored from the list and click on the Select button.
Note: If the tape volume is password protected, you will be prompted for
the password, which you must enter correctly before the tape volume can be
restored.
6. Select all files for this restore procedure using the technique described
in Selecting Files for Backup.
7. After selecting files, click on the Start Restore menu option under the
Restore menu.
8. The restore will now start. If the volume to be restored spans multiple
tapes, BackMaster will prompt for additional tapes as needed.
Note: When restoring multiple drives, you must restore each drive
individually.
ΓòÉΓòÉΓòÉ 9.2. Text Based Restore Utility ΓòÉΓòÉΓòÉ
A text based restore utility is included on the distribution diskette. This
will enable you to perform a restore procedure without actually installing all
of OS/2 and the Presentation Manager version of BackMaster. See the following
section for instructions on creating the two Recovery Diskettes.
o Creating Recovery Diskettes
o Using the Recovery Diskettes
o Using the Text Based Restore Utility
ΓòÉΓòÉΓòÉ 9.3. Creating Recovery Diskettes ΓòÉΓòÉΓòÉ
To run BMREST from floppy, it will be necessary to prepare two diskettes. The
first must be a bootable OS/2 diskette. The first diskette should be labeled
"#1 Bootable". This should NOT be the original OS/2 installation diskette but
a newly created bootable diskette. There are shareware utilities such as
SE20BOOT that will automate this process. SE20BOOT is available for download on
the MSR Development BBS. After the #1 Bootable diskette is prepared, copy
FTDVR.SYS (found on the BackMaster installation diskette) to the root directory
of the #1 Bootable diskette. It may be necessary to delete one or more of the
.COM files from the OS2 directory of the #1 Bootable diskette in order to make
room for the FTDVR.SYS file. You may delete any of the .COM files on the #1
Bootable diskette except COMMAND.COM. Modify the CONFIG.SYS file on the
diskette by adding the following line:
DEVICE=A:\FTDVR.SYS
The second recovery diskette that you will create is the utility diskette.
The second diskette should be labeled #2 Utility. It will contain utility
programs to assist in fixed drive preparation and file recovery.
Format a diskette using the OS/2 (or DOS) FORMAT command. The following files
will need to be copied to the #2 Utility diskette:
o FDISK.COM
o CHKDSK.COM
o FORMAT.COM
o UHPFS.DLL
o BMCOMPR.DLL
o BMREST.EXE
The .COM files may be found on the OS/2 boot drive in the \OS2 directory.
UHPFS.DLL is in the \OS2\DLL subdirectory. If necessary, these files may also
be copied from the original OS/2 installation diskettes. BMCOMPR.DLL and
BMREST.EXE will be in the directory where BackMaster was installed or on the
BackMaster installation diskette.
Note: DO NOT modify the original OS/2 installation diskettes.
ΓòÉΓòÉΓòÉ 9.4. Using the Recovery Diskettes ΓòÉΓòÉΓòÉ
This section assumes you have created recovery diskettes. If you have not yet
created recovery diskettes refer to the section Creating Recovery Diskettes.
The text based restore utility (BMREST) can be used to restore files from a
previous backup of a fixed drive. BMREST is useful in recovering from a drive
crash, accidental deletion of system files, etc. It will not be necessary to
install OS/2 first or use any of the OS/2 installation diskettes. No special
fixed drive preparation is necessary prior to using the Recovery Diskettes.
Boot the system using the #1 Bootable diskette. A full-screen OS/2 command
prompt will appear after the system boots. Then insert the #2 Utility
diskette.
In order for BMREST to restore files to a fixed disk drive, the drive must
first be formatted. If the drive is not already formatted, use FDISK and
FORMAT to partition and format the fixed disk. It is always a good practice to
run CHKDSK /F:2 on the disk to which files will be restored.
Note: Detailed instructions for using these programs are available in your
OS/2 documentation.
Run BMREST to restore files to the fixed drive:
[ A:\ ] BMREST (Enter)
BMREST allows a selective restore, but make sure that all OS/2 files in the
root directory, OS2 directory, and Desktop directory are restored. (If in
doubt, restore the file.) After BMREST has completed, remove the #2 Utility
diskette and reboot the system.
Your system should now be successfully recovered.
Important Notes:
o It is important to use a complete backup for the recovery process. This
insures that important OS/2 files are not missing.
o A backup of the boot drive must be restored to the same drive letter. If a
backup of boot drive C: is restored to drive D:, the system will not boot
correctly.
o In the case of changing file systems (ex: restoring backup of a FAT drive to
a HPFS drive), it will be necessary to copy the correct version of OS2BOOT
to the root directory of the boot drive. There are two separate versions of
this file, a FAT version and an HPFS version. The system will not boot
correctly if the appropriate OS2BOOT file is not installed. Switching file
systems is not recommended.
o The desktops for HPFS and FAT file systems may not be compatible. When file
systems are changed, the desktop may be lost.
ΓòÉΓòÉΓòÉ 9.5. Using the Text Based Restore Utility ΓòÉΓòÉΓòÉ
To use the text based restore utility, first make sure you have read the
section Using the Recovery Diskettes.
Boot OS/2 from the #1 Bootable diskette, prepare the target drive to receive
files, and run BMREST.EXE from the system prompt:
[ A:\ ] BMREST (Enter)
The first screen of BMREST is the configuration screen. From this screen, you
will provide BMREST with information about the source tape drive, the
destination disk and the overwrite options. The keys needed to navigate this
screen are:
Tab To switch between windows
Up/Down arrows To select options within a window
Return To accept all options and continue
F3 To cancel and quit
To select the fixed disk that will receive the restored files, use the tab and
arrow keys. The tab and arrow keys are also used to select the overwrite
options (see the Configuration section) for options and types of tape drives.
Press Return to continue.
BMREST will read the tape header and prompt you with a list of available
volumes on the tape. With the arrow keys, select the desired volume and press
Return. The directory tree display will show the available directories. If a
directory has a [+] indicator, it may be expanded to show subdirectories.
Selected directories are indicated by a partial or full check mark as
described in the section: Selecting Files for Backup. The keys needed to
navigate this screen are:
Up/Down arrows Move cursor among directories
Left arrow Collapse tree one branch
Right arrow Expand tree one branch
Return Select detailed view of file listing in highlighted
directory
Space Bar Toggle file selector on/off
F10 Start restore procedure
F3 Cancel restore
Using the keys described above, select all directories and/or files for the
restore operation and press F10 to start the restore procedure. After the
restore is complete, press F3 to exit the program.
ΓòÉΓòÉΓòÉ 10. The Verify Process ΓòÉΓòÉΓòÉ
Verify allows you to compare files on a fixed disk with files stored on tape.
Verify is useful after a backup to make certain that all files were backed up
correctly. Date and time, size, and data will be compared for each file
selected. The file selection process for verify is identical to backup and
restore.
Note: This version of BackMaster does not verify extended attributes.
o Verifying With BackMaster
o Interpreting the Verify Results
ΓòÉΓòÉΓòÉ 10.1. Verifying With BackMaster ΓòÉΓòÉΓòÉ
The following steps will guide you through the verify process:
1. Double-click the BackMaster icon in the Workplace Shell window.
2. Insert the tape containing the files to be verified.
3. Under the Verify menu, click on Select Files.
4. If your system has more that one fixed drive, a drive selection box will
appear. Select the drive which contains the files to be verified.
5. A list of tape volumes will be displayed. Choose the tape volume to be
compared against the drive selected in step 4 and click on the Select
button.
Note: If the tape volume is password protected, you will be prompted for
the password, which you must enter correctly before the tape volume can be
accessed.
6. Select all files for this verify procedure using the technique described
in Selecting Files for Backup.
7. After selecting files, click on the Start Verify menu option under the
Verify menu.
8. The verify process will now start. If the volume to be verified spans
multiple tapes, BackMaster will prompt for additional tapes as needed.
Note: When verifying multiple drives, you must verify each drive
individually.
ΓòÉΓòÉΓòÉ 10.2. Interpreting the Verify Results ΓòÉΓòÉΓòÉ
After Verify has completed, you will see a dialog box with the following
information:
o Number of files compared.
o Number of files that failed to compare (different dates and times or data).
o Number of files with different dates and times.
o Number of files with different data.
You will be able to quickly see the overall success of the verification
process. If the number of files that failed to compare is 0, you have an
accurate, up-to-date backup of the verified files on the fixed disk. If not,
you will be able to use the Message Log option to see which files are
different.
The Message Log contains the results for each file verified. For each file,
the date, time, and size information that did not compare correctly is listed.
To assist you in finding the files that did not verify correctly, messages are
color coded. The following color scheme is used:
Black (or normal text color)
File compared fully (dates, times, and data compared fully).
Red
Data failed to compare (dates and times may or may not have compared
correctly) .
Blue
Dates and times were different (but data compared fully).

ΓòÉΓòÉΓòÉ 12. Technical Information ΓòÉΓòÉΓòÉ
BackMaster README File.
October 7, 1993.
This file contains information about specific problems you may encounter or
specific system configurations.
Adaptec controllers:
If you have an Adaptec Busmaster controller, the following
CONFIG.SYS setting is suggested:
BASEDEV=AHA154X.ADD /V /A:0 /BON:4 /A:0 /BOFF:12
/V displays messages during bootup. /A:0 specifies the first of
four possible adapters, and is necessary even if only one adapter is
installed. /BON:4 sets the bus on time to 4 microseconds. /BOFF:12
sets the bus off time to 12 microseconds. Most of this information
may be found in the Command Reference under BASEDEV. The above
BASEDEV setting gives the floppy controller enough time on the bus
to transfer enough data (by DMA) to keep the tape moving.
Special thanks to Beta Tester Jay Vanderbilt for this information.
Bus timing:
BackMaster may not work correctly if your system bus timing is set
higher than 8 MHZ. Tape drives are very sensitive to hardware
timing and an abnormal bus speed may result in operational problems
or errors reported by BackMaster.
FTDVR.SYS device driver conflicts:
The BackMaster device driver, FTDVR.SYS, has conflicts with the
Multimedia Presentation Manager (MMPM) drivers and some cdrom device
drivers. The driver conflicts may cause an "Unable to open driver"
error message or an OS/2 TRAP 000D. To avoid the driver conflicts,
make sure that FTDVR.SYS is loaded in CONFIG.SYS after the cdrom
drivers, but before the MMPM drivers.
Note: We recommend locating FTDVR.SYS immediately following the
IFS= statement (if present) in CONFIG.SYS. However, some drivers
(such as cdrom drivers) may have to be loaded before our driver.
Some experimentation on your part may be required to find the
optimal location for FTDVR.SYS.
The BackMaster installation program, BMINST, will place the
FTDVR.SYS in the correct location in CONFIG.SYS for most machines.
The driver conflicts are mentioned here for the case of a manual
installation or a driver conflict with specific systems.
Low memory:
BackMaster may not work correctly on machines with less than 8 MB of
memory. Machines with 8 MB of memory that have network software
loaded may also fall into this category. In the case of a low memory
machine, BackMaster will report the error: "Unable to load device
driver".
Note: This problem may be resolved in future versions of BackMaster
or OS/2.
Older tape drives (Hard Select):
The list of tape drives in the "Configuration Options" dialog refer
to Soft Select tape drives (most of the newer tape drives are Soft
Select), and will not correctly select the older Hard Select type of
tape drive. If you have a Hard Select tape drive, select the
"Generic QIC 40/80" tape drive from the "Configuration Options"
list. Refer to the documentation that came with your tape drive to
determine which type of tape drive (Hard Select or Soft Select) you
have. In general, Hard Select drives may have jumpers to select the
drive (A or B) and will only function as the A or B device, but not
as a third floppy device.
PS/2 support:
IBM PS/2 systems are not currently supported under version 1.0 of
BackMaster. PS/2 support will be added in the next release of
BackMaster.
Stacker:
If FTDVR.SYS resides on a stacked volume, the DEVICE=FTDVR.SYS
statement should be placed after the stacker device drivers.
Time critical:
During normal tape drive operations, BackMaster must respond to the
tape drive signals within a certain amount of time, or the tape
drive may start to behave unpredictably, causing BackMaster to abort
the current tape operation. Active DOS and Windows sessions may
deny BackMaster the CPU time needed to respond quickly to tape drive
signals. If BackMaster aborts in the middle of a tape operation,
make sure that the "Time Critical" check box in the "Configuration
Options" dialog is checked before retrying the tape operation. Time
critical will ensure that BackMaster is given enough CPU time to
respond quickly to the tape drive requests.
Version of OS/2:
BackMaster is designed for OS/2 versions 2.1 and above. It may be
used with OS/2 2.0, but unexpected crashes may occur, especially
during the file selection process. If you must use BackMaster with
OS/2 2.0, we suggest that you avoid extensive opening and closing of
directory folders during the file selection process.
Write errors:
Write errors during a backup are fatal. If BackMaster detects a
write error, it will report the error and abort the backup. It will
be necessary to reformat the tape before making further backups,
since version 1.0 of BackMaster will not update the bad sector map
if bad sectors are found during a backup. Future versions of
BackMaster will update the bad sector map during backup.
