Hi guys,
INFO:
Server: HP DL180 G6
TapeDrive: HP StorageWorks Ultrium 920 SAS
Software: Windows Server 2012 R2 / Backup Exec 15
Problem:
LTO-3 Tapes only have 400GB uncompressed storage, and the tape drive does not support LTO-4 (If I'm not mistaken)
The backups I am doing are 395GB and they fail because (media full)
I have tried to figure out how to setup hardware/software compression, without any success....
Can someone please explain to me how/where to configure the compression?
Thanks

Haven't seen anything outlining that LTO3 can't do hardware compression, and the easiest way to test this is to download HP Library and Tape Tools, stop the BE services and run the compression test. This will tell you whether or not the drive can do this.
We used to get HW compression on 1/8 G2 autoloaders when doing this test on LTO3-based drives with no hassles.
It might be that your data is expanding if it is already compressed which would result in less space being used on a tape.
Thanks!

Hi @pkh
I have figured out that much yes.. Thank you
Even after setting "Software" on the backup job option it does not do any compression..
Please have a look at attached screenshot and advise
Thanks.

My Backup job is running on 2 different server I have noticed that on the one it does compression 3,5:1 and the other 1,2:1
So I am the one that was wrong here, it all is setup and working like it should.
We are just going to look at the data that are being backed up, and make a decision from there on thank you for your help!!

Ah! Got my hardware compression and hardware encryption mixed up again!
