Anyone using Ecrix VXA V17 tapes?
I found this config in the faq-omatic
I have a question:
This drive is supposed to write 66gb with hardware compression.
This config only reflects "length 30609 mbytes" about half of that.
define tapetype VXA {

Which is pretty close to correct, then. Manufactures reports twice the
"native" density when giving the number for compression.

- how do I take advantage of hardware compression?
You fudge the length up from what you think it will do native based
on the amount of compression you expect to get. And here's a tip --
**nobody** gets double :-). I typically see 20-35%.

... I think Amanda with software compression
is smart enough not to compress if it means an increase in size ...
I don't think so. Compression is always done in a pipeline so there is
no chance to recover the original data if at the end it looks like it
was a bad idea.
