I used reiserfs3 (very good) and now btrfs (so-so, but getting better) - stay away from anything ext* - they fall apart under the load eventually losing the lot ... the filesystem gets hammered when its creating tons of hardlinks. From personal experiance I have a very poor view on ext2 and ext3 ... less experience (and failures!) with ext4 though as I avoid ext* on principle now where I can.
First copy takes the same space as the original, subsequent only includes changes (as hard links for existing files use zero space.) Over time, it stabilises at ~2x the original size for full gentoo systems with regular updates (configurable, I keep +2weeks daily, and +6months Sunday backups - dirvish-expire can be a weekly cron job to cull expired versions) My current setup uses a manually run script (simple bash) to pull the wanted directories from a number of vm's and a desktop. I used to do it automatically but until I stabilise my network changes its easier manually. Development looks slow/old from their website, but the activity is elsewhere. BillK * from the dirvish web site "In other news, I've learned from the director of the Oregon State University Open Source Lab that they will be backing up their servers with dirvish. These servers are the primary mirror sites for Mozilla, Kernel.org, Gentoo, Drupal, and other major open source projects. " - if its good enough for them, its good enough ...
