CA Technologies Agent for IBM R12.5 - Manual (Page 31)

Media Rotation Precautions
When the job is complete, a message appears indicating that the restore
was successful. The first restore message results from the creation of the
ON-Bar process. Depending on the progress of the restore procedure,
other messages from actual (not test) restore jobs will follow.
Note: Do not interrupt the restore procedure by browsing IDS objects
from the Backup Manager, or do not attempt to stop the restore operation.
Wait until the BAR_INFORMIX SERVER.log shows that the restore is
complete.
Media Rotation Precautions
Both CA ARCserve Backup and IDS maintain backup histories of the media
used, and other session information associated with dbspaces and blobspaces.
However, during a restore operation, ON-Bar uses the IDS backup history, and
not the backup history maintained by CA ARCserve Backup.
IDS selects the backup session to restore. Depending on its backup history,
ON-Bar may prompt for CA ARCserve Backup media that is no longer in your
media rotation scheme. In this case you may experience a failed restore job.
We recommend that you keep all the IDS log backup sessions after a full
Informix server backup until you complete another Full Backup.
Note: It is extremely important that you plan a practical backup media
rotation scheme, based on a realistic IDS restore scenario. See the
Administration Guide for information regarding media rotation. In general, you
can rotate current media after backing up Informix server-related physical files
when IDS is offline.
Unsupported Restore Functions
The Agent for IBM Informix does not support the following file system-related
functions:
■ Restoring data that was backed up using Disk Staging and with a GFS
rotation schedule.
■ Specifying the following global restore options:
– Create empty path for the root
– Pre-execution or post-execution
