After I saw the series of postings on VXA tape capacity, I thought
it would help to get some info to you straight from us at Ecrix.
In this email, you'll find answers to these questions:
- Which files compress and which don't?
- How does Dantz software compression work with VXA?
- How does a VXA

Sorry,
I missed the NOT in the above statement.
I backup graphics files mostly that's why I get only 34-35 gig on a
compressed tape.

Eh? It really depends on the type of file you are compressing.
If the image (or any data for that matter) is already stored in a compressed

It slows it down and is unneeded as hardware compression is built in.

Rob,
there can be a compounding of tape usage and excessive backup time
caused by poor backup system design & implementation.
This merits explaining:
Streaming tape drives (virtually all modern drives including Exabyte,
DDS-DAT, AIT, VXA, DLT, LTO etc) have a real-time requirement for
data flow.

Rob,
I recall reading, but don't recall where, that this is related to a
firmware issue in the drive. In any case, it would be adviseable
to check the firmware and bring it to current level:
