In the case of the server I'm currently testing, this
seems to be the case. The difference between compression and no compression
was exactly zero: same time both ways.
I looked into the target more closely: it has
single-spindle drives (no RAID arrays), and was connected to the network
via 100Mb. I can't change the target's drives, but I moved the server
to 1Gb and restarted a full. We'll see what happens...
I would not expect the network speed changing from
100Mb to 1Gb to make a difference: this server is literally unchanged
from one run to the next. BackupPC literally shows zero files changed!
So the network bandwidth shouldn't make a difference: all it
should be doing is passing hashes back and forth...
We'll see what happens, though, and I'll let you know.
