my backuppc server is doing a couple dozen VM's and physical machines, 
linux+solaris+AIX+WindowsServer, I have backups going back to MARCH, and 
the whole pool is just a few terabytes, with an effective compression of 
like 50:1 due to the amount of duplication in those backups.   the 
database server machines run a pre-backup script that either does a 
database dump, or a freeze (for instance, postgresql has 
pg_start_backup()), then backup whats right, and run a post-backup 
script (pg_stop_backup())

its worked remarkably well for me, using a fraction of the disk space 
I'd planned for (both primary and mirror backup servers have room for 36 
3.5" SAS drives, although they are only stuffed with 20x3TB in raid6+0
