Been a while and I'd have to double check but...
You might not want to use compression if you use encryption...
I believe it encrypts first then tries to compress and encrypted data
doesn't compress (much).
Something to double check.

Subject: Encryption
Does anybody have any evidence/research as to what kind of additional
overhead encryption puts on a client when processing a backup (CPU,
Memory, etc.)? I am running some tests myself, but the numbers are
staggering (we're seeing up to a 300% increase in the backup time in
some cases). I understand that it is largely based on the horsepower of
the node, but I was wondering if anyone else is seeing the same, or if
anyone knew a place I could get some additional info on encryption.
Thanks in advance for your time,
Josh
