I used reiserfs3 (very good) and now btrfs (so-so, but getting better) - |
2 |
stay away from anything ext* - they fall apart under the load eventually |
3 |
losing the lot ... the filesystem gets hammered when its creating tons |
4 |
of hardlinks. From personal experiance I have a very poor view on ext2 |
5 |
and ext3 ... less experience (and failures!) with ext4 though as I avoid |
6 |
ext* on principle now where I can. |

First copy takes the same space as the original, subsequent only |
9 |
includes changes (as hard links for existing files use zero space.) |
10 |
Over time, it stabilises at ~2x the original size for full gentoo |
11 |
systems with regular updates (configurable, I keep +2weeks daily, and |
12 |
+6months Sunday backups - dirvish-expire can be a weekly cron job to |
13 |
cull expired versions) My current setup uses a manually run script |
14 |
(simple bash) to pull the wanted directories from a number of vm's and a |
15 |
desktop. I used to do it automatically but until I stabilise my network |
16 |
changes its easier manually. |

Development looks slow/old from their website, but the activity is |
19 |
elsewhere. |

* from the dirvish web site "In other news, I've learned from the |
24 |
director of the Oregon State University Open Source Lab that they will |
25 |
be backing up their servers with dirvish. These servers are the primary |
26 |
mirror sites for Mozilla, Kernel.org, Gentoo, Drupal, and other major |
27 |
open source projects. " - if its good enough for them, its good enough ... |
