LVM has a big advantage if not much (relatively) changes between |
| 8 |
backups. If you have let's say 900GB of data, your backup disk is 1TB, |
| 9 |
and say 20GB of data changes between backups, with LVM that drive could |
| 10 |
store 5 *full* backups! You could use btrfs to the same effect. |

Both LVM and btrfs offer snapshotting, so you take a snapshot before |
| 13 |
doing an in-place rsync, giving you one full backup per snapshot, but |
| 14 |
the drive is actually only storing the changes between snapshots. |
| 15 |
Probably run the backup much faster too. |

If this drive is used to store full backups, and only stores the one |
| 18 |
copy, it won't be that expensive/risky to reformat and try that? |
