Netbackup for Exchange server 2013 sp1
Team we are using netbackup 7.6 as a backup solution for Exchange database backup, From last few days we had observed our backup is getting failed and transaction logs are not getting truncated. Below is the error message we are getting.
exmail01 5.5.19 am
Instance 3: The physical consistency check successfully validated 0 out of 7794686 pages of database '\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy301\DB01\T1DB01.edb'. Because some database pages were either not validated or failed validation, the consistency check has been considered unsuccessful.
Instance 5: The physical consistency check has completed, but one or more errors were detected. The consistency check has terminated with error code of -106 (0xffffff96).
looks like it is a exchange issue..
do you see any erros in event viewer...?
see the below blog from exchange and see if that helps
