I doubt that the bzip2 compression would really change backup times all that
much as they are much more I/O contrained than disk bandwidth or CPU bound.
Many time you can see a backup using a small percentage of the CPU but
pegging disk I/O. I'm sure it would have some effect but only a small one

I was trying to do ZFS on freebsd to eliminate the need to have backuppc
compress the files and instead have ZFS do the work. I have since moved to
opensolaris 2008.11 beta as ZFS on freebsd is in alpha quality. Have you
considered this approach or are you bound to your current platform for

Yeah, there is a fuse-zfs port but it is not anwhere near production ready
and the freebsd port is not much closer.
Here is an alternative for you. Nexenta. It is littlerally debian running
an opensolaris kernel. I think it may actually be more ubuntu than debian
but it definitely brings that
Hi everyone,
I installed BackupPC to try it out for backing up Linux systems, and I
have a few questions about it.
First, the on-disk compression format makes me nervous. It appears to
use the deflate algorithm, but cannot be unpacked with either gzip or
unzip. It would seem that the few bytes

means would be well worth it, since it would buy the ability to

because it isn't a completely off-the-shelf implementation, and

Right, I'm aware of that. But that's a specialized tool. It requires
CPAN libraries, libraries from BackupPC's perl library, etc. 20 bytes
or so would get you something that gzip could uncompress.
Are you sure? I thought it also works on its own. Haven't
