Prepare a backup drive

BackSnap has specific requirements for the backup drive used. But these are not difficult to achieve.

The backup drive:

  • Should definitely be an external drive (e.g. USB hard drive)
  • Should definitely be significantly larger than the drive to be backed up in your PC
  • Must be on a different drive than the snapshots being backed up
  • Must be btrfs formatted

Select drive

It is recommended to use a drive that has significantly more storage space than all of the computers being backed up combined. This could be an external hard drive with 2TB, or even more.

Partition and format the backup drive

It is recommended to equip the device with a GPT partition table. The partition to be used for backup must be formatted with btrfs. I have had good experiences with gparted. The name of the BTRFS partition can be anything.

Further preparation

Backsnap can carry out the further preparation itself if it is started in a terminal with the -gi option. Please connect your backup drive so that Btrfs can recognize it. (You don't need to mount it)

sudo backsnap -gi
