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
configurations)
