Yes, I just saw one case here where the guy is trying to upgrade to 
4.6.7 from 4.1.7 and his db is corrupted.

Ok, I'm thinking on focusing on the file server for now, does that need 
a backup server as well or just one with backups can be enough? If one 
is not the case, here is the topology I thought:

1x HDD holding the VMs
2x HDD (RAID 1) for data

file server 1 will use one of the data HDDs
file server 2 will use the other

I don't know if I can use RAID 1 if two distinct machines will use them, 
even though they are VMs

Thanks for reminding me about samba_backup, does that apply for a file 
server only as well?
