Hi to everyone
Our environement is Solaris Sparc 64bit with Netbackup 7.0.1 on SunOS 5.0 (Solaris 10)
Since short time we use a VNC SAN and want to change our Backup-Window from Daily-Full-Backups to a Rotation of Full-Backups and Cummulative-Incremental Backups.
When I controlled the first Backup-Sets, i was very shocked. The Cummulative-Incremental Backups needs not only more than twice the time as the Full Backup; they also save more than double the amount of data.
Is this a normal behaviour for a san-backup ?
As in my understanding, a Cummulative-Incremental Backup retains the differences between the last Full-Backup and the Next-Full-Backup and grows from Backup-Set to Backup-Set. But, within a Backup-Set, there ist an Automatic End. The Backup did not catch unlimited any new open files on the SAN.
Thanks for your Help

Hi Nagalla
Your right
In the meantime, i've consulted our dba's and application administrators and the solutions was, that the database was core-dumped ( cause ? unknown).
So, the only thing, i have to do is, that the colleagues have to analyze the file and/or to clear it for deletion.
Thanks for your fast response.
