BACKUP
If you do not specify a saveset name, you have two possibilities:
• On a random-access device, BUP looks for the saveset BACKUP.BUP.
• On a tape, BUP displays a directory of the first saveset on the tape.
The following example command displays a directory of the files backed up
in saveset TEMP.BUP, residing on DU1:
.BACKUP/DIRECTORY DU1:TEMP.BUP/SAVESET
RT-11 BACKUP
07-May-91 10:54
Saveset: DU1:TEMP.BUP
Created: Monday 06-May-91 09:23
File Blocks Volume Date
TEMP .TMP 2 1 Monday 06-May-91
CACHE .TMP 3 1 Monday 06-May-91
2 Files, 5 Blocks
3. Listing the files in a logical disk
Logical disks backed up with the /SUBSET option have the same format as
regular logical disks. This means you can use the BACKUP/DIRECTORY or
the DIRECTORY command to display logical-disk file directories, whether or
not BUP created the disks.
The BACKUP/DIRECTORY command enables you to list logical-disk
directories without having to mount them separately. To get a directory of a
logical disk, you specify the [ldname]/SUBSET option with the /DIRECTORY
option.
The following example command displays on your terminal a directory of the
logical disk MYBACK.DSK on DU0:
.BACKUP/DIRECTORY DU0:MYBACK.DSK/SUBSET
/FILE
Used only with the /RESTORE option. The /RESTORE/FILE option combination
restores an entire saveset to one file. Two reasons for using this option are:
• For restoring file-image backups not contained within a saveset
Versions of RT–11 before Version 5.5 let you create a file-image backup that
was not contained within a saveset. Such a file image has a format different
from that of a saveset. You restore such a file image from a backup volume
or series of backup volumes by including the /FILE option together with the
/RESTORE option. Because you are performing a file restoration to a disk,
BUP does not initialize that disk as part of the operation.
• For restoring a saveset as one logical-disk file
This is helpful if your saveset file is a logical disk and you want to restore it
as one file.
