A reasonable goal which I solve with rsnapshot =) > Q: Have you been able to recover using your rsnapshot data on the usb drive? I've never tried a full recovery (I use it to recover old versions/deleted files primarily), but since it is (several) full copies of the filesystem, a simple "cp -Rp" or rsync would do the trick. To be clear, I can at this second browse (or fully recover) my "big data" partition as it looked at the following times: drwxr-xr-x 3 root root 4096 Jul 21 13:04 monthly.2 drwxr-xr-x 3 root root 4096 Aug 4 13:05 monthly.1 drwxr-xr-x 3 root root 4096 Sep 1 13:04 monthly.0 drwxr-xr-x 3 root root 4096 Sep 15 13:04 weekly.9 drwxr-xr-x 3 root root 4096 Sep 22 13:05 weekly.8 drwxr-xr-x 3 root root 4096 Sep 29 13:05 weekly.7 drwxr-xr-x 3 root root 4096 Oct 6 13:05 weekly.6 drwxr-xr-x 3 root root 4096 Oct 17 13:09 weekly.5 drwxr-xr-x 3 root root 4096 Nov 3 13:02 weekly.4 drwxr-xr-x 3 root root 4096 Nov 10 13:02 weekly.3 drwxr-xr-x 3 root root 4096 Nov 17 13:02 weekly.2 drwxr-xr-x 3 root root 4096 Nov 24 13:01 weekly.1 drwxr-xr-x 3 root root 4096 Dec 1 13:08 weekly.0 drwxr-xr-x 3 root root 4096 Dec 6 13:04 daily.6 drwxr-xr-x 3 root root 4096 Dec 7 13:05 daily.5 drwxr-xr-x 3 root root 4096 Dec 8 13:03 daily.4 drwxr-xr-x 3 root root 4096 Dec 9 13:04 daily.3 drwxr-xr-x 3 root root 4096 Dec 10 13:05 daily.2 drwxr-xr-x 3 root root 4096 Dec 11 13:04 daily.1 drwxr-xr-x 3 root root 4096 Dec 12 13:04 daily.0 It's not a drive image or anything, so you need to reinstall OS upon drive failure if the drive held your / partition as well before recovering...but those snapshots are fully portable to other machines/architectures on the upside. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
