Saving to tapes with continuation tapes can also be done in other operating systems without operator intervention using an autoloader.
CONTROL provides an option to formulate an explicit operating system command initiating the change of tape. Specify an "l" as "device type" when defining the medium to be used. Then use the OsCmd button to define the command that will initiate the change of tape.
The interactive procedure is the same as for saving to a medium without continuation media.
Example of the medium definition:
At the end of the backup, the tape device shows the number of tapes written. The labels displayed and confirmed at the start of the backup (Step 3) should be put down on the stickers of the tapes.
Batch Call:
Syntax:
Example:
xbackup -a SAVEDATA -d mydb -m AUTOL
The complete description of the batch calls is included in Section Batch Mode: xbackup / xrestore.
To display the protocol file of the batch call, you can use the Backup / Show Protocol menu function.
Restoring by means of an autoloader is done in the same way as saving. Simply use the same medium definition as for saving and perform the restore operation as if restoring from one medium. To ensure a successful restore, all tapes belonging to the save must have been mounted to the autoloader.
Use the xrestore command as batch call.
