Question/Problem Description
Incremental online backup takes too much time to complete in proportion to a full offline backup.
 
Steps to Reproduce
Clarifying Information
No users are connected at the time the backup is done.
Error Message
Defect/Enhancement Number
Cause
Backup is being performed on a RAID 5 disk.
Additionally probkup online stores the Before Image along with the backup.

 
Resolution
Avoid doing any backup in a RAID 5 disk.

Do the backup to a local non-RAID 5 disk first,  then copy the backup to the RAID 5 disk.

Note: It is important to highlight that incremental online backups are much less efficient than incremental offline ones. This is inherent in the design of the probkup online.
