BACKUP
BACKUP
The BACKUP command displays the status of backup requests and lets you back up
specific subvolumes related to database incidents.
STATUS
lets you query the status of backup requests.
Inc-rec-num
specifies an incident number retrieved from the REPORT command incidents list.
Tape-Unit
is the tape drive used for the backup.
time
is the number of minutes a backup request will delay. The minute range is from 1
through 1440. The default value is 1.
Guidelines
•
To learn about record numbers, see the REPORT command on page 4-32.
•
If no tape unit is specified, the tape unit configured through the TAPE command is
used.
•
The time directive supersedes the current default set by the BACKUPDELAY
command.
•
When performing RESTORE (a NonStop Kernel command), use the OPEN option.
Failure to do so results in an error message because the TFDS incident database
files are open at the time the backup is performed.
•
When you specify an incident number, you initiate the backup of files related to the
incident in the incident database.
Examples
•
This example requests a backup in 5 minutes on $CART1 of all the files in the
subvolume associated with incident number 4 that have not been backed up:
BACKUP 4 $CART1 TIMEOUT= 5
•
This example requests an immediate backup of all the files in the subvolume
related to incident number 16:
BACKUP 16
Because no tape has been specified, the tape specification comes from a
previously specified TAPE command.
BACKUP { STATUS }
{ Inc-rec-num [ Tape-Unit [ TIMEOUT= time ] ] }
