As for restore, each backup is effectively an uncompressed fully accessible mirror image so you can manually copy/tar/... etc back for the full system, or individual files. The developers basically say we have a working backup system where you can restore using standard tools 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 typically stabilises at 2x archive size depending on delta. Downside it can hammer a disk - reiserfs is fine but ext2/3 was flaky. moriah ~ # esearch dirvish [ Results for search key : dirvish ] [ Applications found : 1 ] * app-backup/dirvish Latest version available: 1.2.1 Latest version installed: 1.2.1 Size of downloaded files: [no/bad digest] Homepage: http://www.dirvish.org/ Description: Dirvish is a fast, disk based, rotating network backup system.
