Backup Exec 12.5 loading media (won't finish backup)
I have a standalone HP backup system that I use Symantec Backup Exec 12.5 to backup all my servers.
Currently I backup every Monday, Wednesday and Friday, I do full backups as well and I have it set to Ovewritable - Infintie - Allow Append
I use LTO 4 tapes and I have had no issues with doing full backups like this for the past 3years.
Now I am currently putting my tapes in on Monday or Wednesday or Friday and when I come in the next day to check on the tape its already ejected and Backup Exec says it wants me to load more media, like the Tape got full, Which is shocking to me because I have 100% complete Backup sets and the total bytes is 1,106,355,775,970
Like I said above I have always had 100% success and verified data that large on an LTO 4 tape so its not like there getting full, its acting like its not compressing the data.
So what I have done so far is:
Cleaned the Backup Unit
Long Erased a Test tape and put it back in and it still didn't work
Currently its stopping around 789GB's and then it ejects the tape and wants me to load another tape before it finishes.
Any ideas?

Ok well so far I think the Compression is the culprit, but is it hardware related or not, I just found updated HP drivers for the device so I installed those from 2008 to a 2010 driver.
Compression is definitly turned on but its not doing a 2:1 compression its doing 1:1 or 1:3, it could be the tapes I suppose.
I will start with the driver update to see if that resolves it
if not then I will order new cleaning tape and new tapes and see what happens

The compression ratio will depend on your data not the tapes

Well the compression was definitly the issue, its a hardware issue.
I just changed my backup scheme to accomodate for this until I can replace.
Thank you all for you help

The drive should tell you if it needs cleaning.
