Backups

Our current notion of backing up seems to conflate two things that should be kept separate:

  1. Implementation robustness: You don’t want to lose the state of a higher level service due to losing state in a lower level service.

  2. Preservation of history: You want to be able to revert to a previous state.

1 is probably best dealt with things like RAID and distributed filesystems.

2 is probably best dealt with things like version control and versioned filesystems.
