Netbackup Appliance deduplication/re-hydration problem
Netbackup Master Server Version: 7.5.0.7
Netbackup Appliance 2530, Version 2.5.4
Netbackup Appliance Media Server Version 7.5.0.7
Backup Type: Exchange DB Backup (DAG) with GRT
Client OS/Version: Windows Server 2008 RT, Netbackup
Help! One of our Netbackup appliance hosts Exchange Database backup (DAG) with GRT... Backups do run with good speed and without any issues during normal circumstances... These backups are set to duplicate to tape (managed via SLP), everyweek... As soon as the SLP starts to copy the data from MSDP to tape, the backups' speed becomes haywire and runs extremely slowly.. As soon as I kill off the duplication job, the backups revert to normal again...
Another problem is that, whenever the duplication run the exchange backups fail with error code 24 or 42 (Network Write error or Network Read error).. This doesnt happen during normal backups... Please help on this.
Also, it would be highly helpful if someone could explain de-duplication/dehydration workflow and duplication to tape workflow (via SLP)...
