I am using Symantec Backup Exec 2010 in conjunction with an HP Storagewors 2024 tape library system. It used to compress the data well. As we are using 400/800gb tapes. For awhile now it is just going a 1:1 compression and is taking a lot of tapes.
I have contacted Symantec and they claim the tape library does the majority of the compression and to check on that. So not very much help.
I started contacted HP support last week, and I think my library is just out of warranty so will have to pay for support.
Any ideas of how I can get my data to start compressing again?
