Note I am just starting out with this whole backup setup so it does not have a track record yet.
We have a NEO2000e tape library with an Ultrium 4 SCSI drive (user mode driver), I am using LTO3 tapes. Operating system is Server 2003. I have the "Enable compression" box ticked
on the tape device. When I do a backup (file types are typical desktop drivers, laptop drivers, printer drivers) I am only getting 1.1:1 compression. Drive is new and
tapes are new.
I click on one of the media and it tells me-
Used Capacity: 0 bytes of 390.9 GB
Available Capacity: 390.93 GB
Total capacity: 390.9 GB
Bytes Written: 1.5 GB
WHY is my tape AVAILABLE CAPACITY 390 GB ?? I understand compression relies on the type of data, data streaming speed
to drive, etc. But why would it show me just 400 GB (basically)? Wouldn't it show me ballpark 790 GB capacity IF compression
is on and working??
Driving me nuts. Don't want to eat up the small amount of tape media I have as it is.
