DISASTER RECOVERY
トトトトトトトトトトトトトトトトト
Backup Basics includes two DOS commands which allow you to recover your
workstation in the event of a system crash:
BEDDIR - gives you a listing of files on a backup tape
and
BEDREST - allows you to restore files from the tape to a disk.

HOW TO RESTORE A CRASHED WORKSTATION DISK
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
1. Install, partition and format your hard drive according to the
manufacturer's specifications and your DOS manual.
2. Install the Backup Basics disaster recovery diskette.
3. Locate the tapes that contain your latest full backup and
incremental or differential backups. If you do not know the
contents of your tapes, you can use the BEDDIR command to obtain a
directory listing of each tape. See using the BEDDIR command.
4. Once you have located the tapes that contain your latest backup(s),
use the BEDREST command to restore the data. See using the
BEDREST command.

HOW TO USE BEDDIR
トトトトトトトトトトトトトトトトト
BEDDIR allows you to list the files on a tape.
Here is the complete syntax for the command:
BEDDIR [\path\][filename.ext][/parameter]
For example, to list all of the files contained on a tape, type:
BEDDIR C:\ /s
This will list all of the files on the tape while logging them in the
BEDOS.LOG file which can be read using the DOS TYPE command:
TYPE BEDOS.LOG | MORE
The [\path\][filename.ext] fields allow you to specify the directory and
files on the tape that you want to display.
Optional parameters are described below.
トトトトトトトトトトトトトトトトトト
HOW TO USE BEDREST
トトトトトトトトトトトトトトトトトト
BEDREST allows you to restore files from tape to disk.
Here is the complete syntax for the command:
BEDREST [device:][\path\][filename.ext][/parameter]
For example, to restore all of the files from a tape to a hard disk, type:
BEDREST C:\ /s
The [device:] field specifies the device to which you want files
restored. If no [device:] is given the default device will be used.
The [\path\][filename.ext] fields allow you to specify the directory and
files on the tape that you want to restore. If no [filename.ext] is
given, *.* is used.
NOTES:
- If the backup spans multiple tapes, you will be warned if the tapes
are inserted out of order
- Results of using BEDREST will be logged to BEDOS.LOG which can be
read using the DOS TYPE command:
TYPE BEDOS.LOG | MORE
Optional parameters are described below.

COMMAND LINE PARAMETERS
トトトトトトトトトトトトトトトトトトトトトトト
Parameters are used to customize BEDREST and BEDDIR operations:
[/d[:mm/dd/yy][:mm/dd/yy]]
BEDDIR
BEDREST
To specify listing, or restoring files after a given date, before a
given date, or between two dates. If no date is specified, the
default date (today's date) is used. The first date is the AFTER
date, the second date is the BEFORE. Example: To restore all the
files created in July 1993 (ON or AFTER July 1st and ON or BEFORE
July 31st) you would type:
BEDREST C:\ /s /d:07/01/93:07/31/93
To restore or list files created or last modified before a given
date, but not after a given date enter two colons after this
parameter. To list all files on drive C: created or last modified
on or before October 1st, 1993 you would type:
BEDDIR C:\ /s /d::10/01/93
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/em]
BEDREST
To include empty directories during the restore.
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/na:n]
BEDREST
To restore Macintosh Appletalk File Protocol (AFP) information on
Novell NetWare 2.15 or greater. n can be 0 or 1. If you specify
/na:0, Macintosh AFP information is not restored. If you specify
/na:1 (the default of this option), Macintosh AFP information is
restored if present. Example:
BEDREST C:\ /s /na:0
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/page]
BEDDIR
To have BEDDIR pause and prompt when the screen is full of listed
files. Example:
BEDDIR C:\ /s /page
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/pr]
BEDREST
To have BEDREST prompt you before restoring files that have changed.
Example:
BEDREST C:\ /s /pr
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/q]
BEDREST
When /q is used, a file that already exists on the disk is not
restored. Only files that are on the tape, and not on the disk,
are restored. Example:
BEDREST C:\ /s /q
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/s]
BEDDIR
BEDREST
To list or restore all subdirectories under the specified
directories. Example:
BEDREST C:\ /s
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/-s]
BEDREST
The /-s option excludes special files from the restore operation.
Special files are marked with any combination of the system or
read-only attributes. This option is helpful when used with copy
protection and networks. This option prevents files like IBMBIO.COM
and IBMDOS.COM (among others), from being restored. Be sure to
specify the minus "- " in the command or this option could be
confused with the subdirectories (/s) option. Example:
BEDREST C:\ /-s
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/v:n]
BEDDIR
BEDREST
To direct the command to the correct backup set on the tape before
beginning the directory or restore operation. Example: If the
second backup set on the tape contains the files you want to list you
would type:
BEDDIR C:\ /s /v:2
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/w]
BEDDIR
To display file names on the entire width of the screen. Example:
BEDDIR C:\ /s /w
トトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトトト
[/x]
BEDDIR
BEDREST
This parameter is used to exclude files that match the file specification.
Example: To restore the entire drive C: but exclude all of the
files in the root directory you would type:
BEDREST C:\ /s C:\ /x
Files are processed in the order they are specified for each
device. Example:
BEDREST C:\*.* C:\*.bak /x C:\fred.bak
This includes all files in the root directory of drive C: (*.*). It
then excludes all files in the root directory that end with the
extension .BAK (*.bak /x). Finally, it includes the file called
FRED.BAK.
The order of included and excluded files is very important. If you
were to take the above example and rearrange it, the outcome would be
different. Example:
BEDREST C:\*.* C:\fred.bak C:\*.bak /x
This would include all files in the root directory of drive C:
(including FRED.BAK whether the file is mentioned or not), then all
files in the root directory that end with .BAK would be excluded.
FRED.BAK would not be restored because *.bak /x comes after fred.bak
in the command line.
