Currently I am using Emc Avamar it is great and I will continue to use it for my company. The problem is that I have to offshoot three smaller companies from my larger one. I would like to have some sort of back up plan that is free or open source. I have found Amanda, Bacula, Fog, and URBackup, but I don't know a thing about any of them and would like some advice.
Basically I want to do
Incremental image level backups of 3 servers
Workstations are secondary but would be nice
I would like it to dedupe - or at the very least compress data
Any guidance on a freebie solution would be appreciated, thanks
