Thanks Mark.
From the zfs man page for zol it looks like the default compression is
lzjb, same as other zfs implementations. I generally use lz4 which is
basically lzjb with some performance upgrades. It's a minor tweak unless
you have a lot of uncompressible files.
If you are experiencing de

Mark,
Questions, and some comments.
Questions:
What have you done to tune your zfs?
Do you use a ZIL? and or an L2ARC?
How much ram do you have?
What compression level are you using on zfs?
I reflexively put a ZIL on my system but I'm curious if anyone has
experimented with BackupPC performanc
I too am using ZFS, and I can honestly say that ZFS works great, up to a point.
rsync does seem to take up an inordinate amount of resources, but in a smaller
shop like mine, it's been tolerable. I think it would work in a larger shop
too, but the system resource requirements (CPU/RAM) would g
