Doesn't this do the same as $ rsync --inplace?
The difference is important when you have many 50GB VM disk images with just 2-3GB occupied (as I have).
Rsync doesn't support --sparse --inplace.
Also the virtsync command line is more similar to scp than rsync. No need for any configuration files - it uses ssh as its transport.
$49 per machine is a pretty high cost, particularly for something which is new and untested. I'm no expert, but my gut feeling is that for this kind of tool - you need to offer a more 'enterprisey' offering. The way budgets for the kind of places that this tool would be useful are allocated, $49 for a single utility for every machine it might need to be run on is something that sysadmins might have difficulty explain…

Are you looking for people with dedicated backup and recovery?
Are you looking for people without BaR but uses a lot of VMs?
Should I backup anything with this, or just my VMs and DBs? If so, how does it compare to [existing VM or DB backup system]
How does it compare to using rsync with hpn-ssh? Using hpn-ssh significantly improves rsync speeds, though I don't know how it works with sparse files since I use dedicated SAN backups for my VMs.

Interesting thoughts. Perhaps I should change the interface so that it is drop in replacement for scp?
