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.
