Specifying a File-Set List for Backup
If the tape drive is in use by another process, Backup returns file-system error 12
(file in use) and stops. If this happens, select another tape drive and start again.
4. Mount your write-enabled tape according to the directions for the specific tape
drive. Press Return.
Backup copies the files from $DATA.USER to the tape on $TAPE1.
This procedure ensures that you have control of the tape drive before you put your tape
online. If you mount your tape before you enter your Backup command, the Backup
operation begins immediately without the “Not ready?” message. If the drive is already
controlled by another process, this process could write to your tape.
Specifying a File-Set List for Backup
You can back up any files on your system to which you have read access. To back up:
•
A single file, specify the file name in your Backup command.
•
More than one file, specify a file set or file-set list.
A file set is one or more related files in the format:
[\system.][$volume.][subvolume.]file-id
If you omit the \ system , $ volume , or subvolume , Backup uses the current default
system, volume, or subvolume. For example, if you supply only a volume name
followed by a file identifier, Backup fills in the subvolume name.
You can include these wild-card characters in the volume , subvolume , and
filename :
* (asterisk) Matches zero to eight character in the same position where it
appears
? (question mark) Matches any single character in the position where it appears
These characters cannot be used in a system name or for the volume identifier ($) or
field separator (.). Also, some Backup command options do not allow these characters;
see the Guardian Disk and Tape Utilities Reference Manual.
Examples of file sets are:
Note. Avoid using subvolume defaulting. This feature might not be supported in future
releases of Backup.
$MYVOL.EXTRA.INFO The file INFO in the subvolume EXTRA on volume $MYVOL.
MYFILE The file MYFILE on the current default subvolume and volume.
*.* All files on the current default subvolume.
$Z*.SUB*.* All files in subvolumes that have names beginning with SUB on
every disk volume that has a name beginning with $Z.
