Netbackup 7.5.0.7 DAG .img filling up my disk
Hello,
We are running NB 7.5.0.7 on a Windows 2008 R2 machine. We back up our Exchange 2010 server DAG. The backup job creates .img and .info files that are filling up our disk on the netbackup machine. Are these supposed to truncate after a certain amount of time? Can they be deleted? Thanks and please let me know if more info is need.
Regards,
George
You have created a Basic Disk Storage Unit where Exchange Backups are written to, right?
Hopefully you have created the DSU on a separate volume and not just a folder on the same volume as the NetBackup installation?
There are 2 factors that control the lifespan of images on disk:
- The retention level specified in Policy schedule
- The High Water Mark of the DSU IF you have configured staging to tape.
HWM is only useful if the DSU is on its own volume and if staging is configured. When the HWM is reached, NBU will cleanup oldest images that have been duplicated to tape until the LWM is reached.
