So I tried this out. Although I had a couple of directory issues getting it ready to go it did run eventually. My issue at this point is a matter of gaining confidence that it backed up the right stuff. Considering my file system usage the file size seems smallish at 1.2G. lightning ~ # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 9.2G 6.5G 2.3G 75% / udev 10M 184K 9.9M 2% /dev /dev/sda6 3.7G 740M 2.8G 21% /usr/src /dev/sda8 14G 11G 2.5G 82% /home shm 497M 0 497M 0% /dev/shm none 497M 0 497M 0% /tmp/jack lightning ~ # The terminal where it ran said it backed up about 3.3GB into a 1.2GB file. My file system usage (for a minimal backup) is roughly the 6.5GB on / since minimal doesn't back up /home and /usr/src which I convieniently have on separate partitions anyway. I wonder if half of that 6.6GB really isn't needed? Anyway, the scripts seemed to have worked, but how to verify? That's the question. Could I restore this backup into a different subdirectory somewhere and then chroot into it? - Mark -- gentoo-user@lists.gentoo.org mailing list
