Well, tar and cpio are good choices because they are available on the Gentoo live CD. If you chose another program, you will just need to make sure that you have a static binary of it available at recovery time (copying this to your recovery media is the best choice). I am currently using 'dar' to backup to external USB hard disk. Dar is also useful for backing up to DVD media though, because it has good support for creating archive 'slices' that will fit nicely on a DVD, just in case you decide to backup /home as well. It is in portage, but if you are interested, check out http://dar.linux.free.fr/ For 'quick-and-easy' restoring, I'm not aware of anything that really automates the process. But generally the steps are: 1. fdisk 2. mkfs 3. mount 4. restore files 5. chroot 6. install boot loader 7. reboot The difficulty in restoring the files will really depend upon how you make your backups (always full, incrementals, differentials, etc). A full backup would always be the easiest, as you only need a single piece/set of media and one command to do the restore. The rest of the steps are pretty much exactly the same as for when you installed Gentoo, so there shouldn't be any real surprises there. One last thing, if you've only got a single CD/DVD drive, you are probably going to have an issue to have both the live CD and the backup media available, since you can't really eject the live CD to insert your backup disk. -Richard -- gentoo-user@gentoo.org mailing list
