I can't speak for zfs. I had upwards of 1000 snapshots on my system |
| 6 |
before I stopped creating them hourly and and just started having |
| 7 |
issues with it. |

I wouldn't really say it is ready for prime time, but it is workable. |

Of course, you'll still want backups - a million snapshots does you no |
| 11 |
good if some bug wipes out your filesystem. For one of my ENOSPC |
| 12 |
incidents I ended up just wiping the entire filesystem and restoring |
| 13 |
from backup, though if I kept at it I'd probably have been able to fix |
| 14 |
it. |

Oh, one other tip if you use btrfs - be sure you have a rescue disk |
| 17 |
that supports it. Hint, the old Gentoo install CD I had lying around |
| 18 |
didn't. You'll probably want to keep a rescue CD with a recent kernel |
| 19 |
and btrfs-tools handy at all times. |
