We are using 12.5 Netbackup it was working fine. As we moved our mail server from Lotus to Exchange 2010, we need to take backup of DB/other. So moved from 12.5 to 2010. We have 2008 R2 server 64 bit, Backupexec 64 bit, DB size is 500GB (approx), we have HP LTO 4 tape library. We connected one to one (Server to Tape lib) thru LAN (1GBps). It took 18 hrs to take backup. On taking next backup it got failed, and it was frequently failed.
Do we miss any configuration/logging?
