It's windows file and print data. Looks like our results are similar to yours.
Coming from the original servers to JA tapes, we were getting between 575 and
675GB per tape. So far on the JBs coming from CIFS, it looks like 820 to 900GB
per tape. I think my main problem was I was using the 300GB uncompressed number
for the JA tapes and it is really 500GB.

What kind of data? We are getting 750GB - 1.2TB on each tape. The compression
is similar to what the original file servers got when they wrote to a different
library and different drives.

We have just purchased a bunch of 3592JB tapes (700GB uncompressed capacity) to
use for some large NDMP backups. My first test last night backing up around
1.8TB of data completely filled two of these tapes. This is only marginally
better than what I was getting on the 3592JA tapes which are rated at 300GB
uncompressed. We have 8 TS1120 (3592-E05) drives in a 3494 library and are
running TSM 6.1.3.4. The device class specifies FORMAT=DRIVE which should
cause recording at the highest available density. I would think almost all of
this data would fit on one of these volumes. Any ideas where I am going wrong?
