[Cialug] VMs & Replication

[Matt Breitbach]

I'd look at a SAN level backup.  Nexenta has done quite well with their
Auto-Snap service.  Basically, you snap the SAN environment, replicate on
your schedule (every minute, 5 minutes, hour, day, week, whatever) and
retain a specified number of days.

Restore process is pretty decent.  Only drawback is that you've got to pay
for the software (Nexenta).  The Auto-Tier service that's provided with the
community version isn't well suited to off-site replication (bandwidth
intense).

60GB disk, various snapshot sizes of one-week intervals.  The 60GB image 
was the original P2V footprint from an original server.

Your mileage may vary, but I can't stress enough my recommendation that 
you test your snapshot/consolidation paradigm prior to deploying it as a 
strategy in a production environment.  Read the VirtualBox forums on 
snapshots - a lot of folks won't use them at all in a production 
environment.
