Backup advice (physical and virtual)
I'm looking for some advice on backup infrastructure for the following:
1x Physical DC
1x Physical host running:
2x Hyper-V VMs (1 DC/File Server (all roles) & 1 Member Server (WSUS, WDS, AV, etc))
All servers are running 2008 R2.
I'd like to backup to NAS (daily) and then weekly using portable USB HDDs for off-site storage. We have an old (v9.1 IIRC) version of BE that if used will obviously need upgrading to v2010.
So, do I go for BE 2010 and take advantage of upgrade pricing? If I do, would BE be installed on the physical host and set to backup the VMs at that level? Am I correct in thinking that that would then still enable file level restore of the VMs and Virtual Discs without the need to backup each one separately from within the VMs? I'm a little confused by the licensing model and different versions of BE! Alternatively, I could try DPM...
Any suggestions would be much appreciated.
