Backup of Volumes
If I turn on backups for my linode and there is an attached volume that is mounted in the OS (via fstab), does that volume get backed up also? Or does the backup only work on the primary disk?
Our Backup Service is currently not able to back up the data on a mounted Block Storage device. You would need to back up the Block Storage through other means - e.g via rsync.
