I have recently started in an environment that is using Netbackup 6.5 for backups. Currently the backup windows are barely being met and I was wondering if there are some changes that could be made at least in some areas. I have never worked with Netbackup, and in fact have always worked with disk to disk backups, and never with tape.
There is about 9 TB of data that need to be backed up. There are 2 backup servers, one with (2) LTO 3 tape drives, and one with one LTO 3.
1. Is compression for the tape done on the drive itself? Is this automatic, or something that has to be enabled? Also does this work with any compression that is done by Netbackup, or is it one or the other?
2. Can block level incremental backups be done with Netbackup 6.5? I have looked and looked, but cannot find anything relating to 6.5. plenty about BLIB for VMs in 7.0. I also see an option in the software for Block level incremntals, but only under the snapshot feature.
