[PVE-User] Backup size

[VIDAL, Thomas (Bioversity-France)]

Dear Gilberto and Diaolin,

Thanks for your help.
But I have only linux debian server, and this happens also with the 
fresh and last one I just setting up with nothing else except the basic 
filesystem (500Mo) and for this VM I set a 80G of disk, and then the 
backup size is 20G !
The thing is if the disk of the VM is 32G, the backup is 17G, if the 
disk of the VM is 100G the backup file size is 30G, and for these VM 
there are nothing except a basic debian system (with no X)
Since I am using Proxmox I didn't change the storage (DELL MD3200i) and 
the physical server ! It appeared suddendly, maybe with one update, I 
don't know.

Many thanks for your help.

Have a nice week-end

Thomas

The software said "Requires Windows 2000, Windows XP, or better,..."
So I installed Linux Mint !
