That was the question posed on linkedin:
Rsync or Bacula?
A short answer and a middle point:
It can use rsync with all its functionalities, you get a web interface for management,compression, pooling, multiple schedules, differential/incremental/full backups, win a lot of disk space and a security interface.
I use it for my home servers as well for my companies one (managing more or less 50 servers (windows/Linux) and it works like a charm.
The Best of it… it’s open source and have a lot of community support for it.

Ps – if you can run it over solaris with ZFS… even better 😉
