It actually does a very fast, space efficient backup management. |

As for restore, each backup is effectively an uncompressed fully |
| 4 |
accessible mirror image so you can manually copy/tar/... etc back for |
| 5 |
the full system, or individual files. The developers basically say we |
| 6 |
have a working backup system where you can restore using standard tools |
| 7 |
if needed, but we'll make it easier when we can get around to it. |

Having versioned backups can be REALLY handy at times. Space efficiency |
| 10 |
typically stabilises at 2x archive size depending on delta. |

Downside it can hammer a disk - reiserfs is fine but ext2/3 was flaky. |

Its worth a read on how its done - using smarts rather than brute force! |
