[ovirt-users] VM incremental backup

Hi Yaniv,

how can this be done with DD ? Since it doesn’t know if the block is free space ? I’ve been looking for such a solution for a long time now. Everything I could find out was that I have to use a utility that understands the FS and therefore knows where the free space is.

Thank you,

Full VM disk backup. If you use dd you can drop the 0 parts of the disk.

Is there a preferred or recommended backup method in the meantime ?

I would like to understand the existence of the possibility of incremental VM backups.
And if it is, the means by which it is achieved.
While I was only able to achieve a complete backup of the virtual machine (but it is a very large amount of information and time) by cloning a snapshot of the VM and export to data domain.
