Backupexec tape compression
Hi - sorry if thread in wrong place
I have just put backupexec 11d on 1 of my servers at school. This was to replace v9, which stopped working with the finance updates in dec.
I have a older sony ati tape drive (35GB / 70GB compressed)
The backup is about 85 GB, although i can make smaller. But everytime i've tired to backup this up, it takes 3 tapes to backup.
Now i'm guessing maybe i would need 2, as it's over 70GB, But the tape's putting about 37GB on 1 before spitting it out.
My question is why / how is the compression not working on the drive?
I have gone into the backupexec / options / backup / compression type and set this to hardware (it aval, if not software) but have tried software + hardware setting, with no luck so far (i have checked settings of backup exec against some of my other schools, all settings are pretty much the same, so hopefully not something i've done wrong in setup)
The only thing worth mentioning is sometimes the tape drive not see the media in it. If i retension + erase the tape, it see's it, however the compression is still not kicking in. Have run backupexec + server 2003 updates.
Any ideas or suggestions to what i'm doing wrong? Are there any windows settings for compression etc?
(The tapes + drive are 3/4 years old now)
Thanks in advance........
