Does this Disaster recovery safe cluster architecture possible with BackupPC?
Let say we have 2 sites A and B
Let says that we have 3 hosts per site to backup
hosts 1A 2A 3A for site A and 1B 2B 3B for site B.
If we declare hosts 1A 2A 3A plus hosts 1B 2B 3B as archive hosts on site A
and at the same time
we declare hosts 1B 2B 3B plus hosts 1A 2A 3A as archive hosts on site B
then each night we to an "rsync-2.6.6 -H" (on /var/lib/backuppc/pc) between
the 2 sites.
Then we have nightly pool optimisation.
Can this config work. If not why?
If it can work, can we have the benefit to optimise redundant files between
the 2 sites?
If one server fail, is there a way to recovery host 1A on site A from B site?
In normal operation, is it possible to download/recover files on host 1A from
host 2B on site A?
It such config could run (network is not a problem here), it would be realy
cool as I wouldn't have to backup the backuppc server :-)
