Subject RE: backup a cloudstack deployment

Hi Nik,

The whole point of Cloud is that the applications running on them are Cloud Aware, and should
be written to cope with an element of failure.

I recommend that you do regular backups of your MySQL DBs, and also Secondary Storage.

You should have every VM running a Scheduled Snapshot routine, that way if you have a disaster,
you can recreate your architecture, and restore VMs from Snapshots / Templates

I depend on secondary storage and the Volume snapshotting utility to backup important VMs,
but if you want more than that, you'll want to do something like backup your secondary storage
to tape or a tertiary disk storage volume.  But I also run dual active-active SAN, so my vm
data is already on two different SAN nodes at all times, PLUS a secondary storage backup
