Depending on the data, yes. Usually, with compression enabled, you'd
get more than 100G on each tape.

Have you run the btape 'test' procedure?
Do you see any SCSI-related messages in the system's log file?
And yes, 6MB/s is rather slow for LTO-1, but the bottleneck could be
elsewhere.
To get good speed, you need to do a bit of performance tuning, but
let's see the answers for the above questions first :-)
By the way - I believe Kern will mention performance tuning on his
upcoming webinar. A link to regsiter is at
http://www.baculasystems.com/eng I don't know what he'll present in
detail, though...
Cheers,
Arno
