We had a client using BackupPC. Maybe for a single PC it works well.
They were backing up several (well over 10) PCs to a NAS. It hammered
the system in both I/O and CPU. Combined with some (old kernel)
filesystem bugs, it would mangle the filesystem. It seems to do the
rsync protocol _in Perl_ at the BackupPC end, and uses an elaborate
hash-named file tree for the deduplication function. It needed a special
web interface to browse/restore.
It kind of works, but does not scale.
Looks like you haven't taken a look in a while. BackupPC 3.x used a perl version of rsync to add the extra stuff it needed to work, but BackupPC 4.x (which has been released for a few years now) forked rsync to provide the magic. It also now uses sqlite instead of hard links to manage deduplication.
I only backup about 6 computers but it's for a home environment. I've currently got 6.36TB backed up only consuming 675GB of space.
Thanks,
Richard
