I had the chance to actually try this module - and it does come with a number of issues. Restoring files with it was a major pain - as I decided to leave cache on and statistics on - that in itself was a stupid choice, but hey maybe someone needs them. Automatically that made my backup around 12 GB. When I tried to restore the backup to a fresh Prestaserver I had loads of DB errors that I had to manually patch for hours. I suggest using N2 backup if you want a reliable full backup or if it is just moving data MigratePro.
For small backups though, this is a lot better due to its speed. Blows the others out of the water.
