Good Day
Using backup exec 12.5 SP5 on Win2003 server with HP Ultrium 3 SCSI tape device.
Our LTO3 tapes only get half used but indicate full. Tried software compression on/off - no difference. Tape drive doesn't support H/W compression.
Regards
LTO3 drives have on-board compression - Compression on a software level, increases server overheard.
ZeRoC00L is right on the money - depends on the data - Vote +1
so is CraigV - update tape firmware - Vote +1 - have your vendor do this if still in warranty.
Used capacity is 390GB, so that is the uncompressed media size.
If data is not compressed, it is 1:1 which means that the tapes would fill up as much as possible...not stop at 50%.
When I see the screenshot it looks like there is not used any compression.
What kind of data are you trying to backup? Maybe it is uncompressable data?
Hi Michael,
I'd suggest the following:
1. Use HP Library and Tape Tools (HP LTT) to update the firmware on your tape drive.
2. Get the latest drivers (and maybe any available updates too!) for Backup Exec 12.x and install them. Once done, run the Device Configuration Wizard and install the latest Symantec drivers. Try a backup job again, and post the results here...
Laters!
