sounds reasonable for an automated backup (the author of the post you linked to said it takes about 50 minutes).
i just backup manually with partimage. takes about three minutes to backup my whole system (minus /home and distfiles etc.) to an image on another drive. ditto to restore it (plus a couple more minutes if you count booting from the rescue disk, i guess). i have my /home directory on another partition and back that up fairly regularly. regular data backups are small enough that i just copy 'em straight onto the other drive, or a CDR if i'm paranoid (which i am from time to time) and want the data separate from the pc (and the building, for that matter).
i have (old, i admit) copies of the partition images on DVDR too. i keep my partitions under 5 gig so i can back them up this way. |

Tape backups are cheap, you can get a DDS2 tape drive for next to nothing these days off ebay, and then just use mt and tar to do a backup.
I have a bash script that i wrote that just does a backup of the dir's i specify and then checks that the backup worked.
It takes less than 30 min to do about 8gig of backup to tape, and another 30min for the check.
If you want to take a look at the script i use, you can get it off my website here.
You can modify the script to create a stage 4 backup (like the one you linked to) then just transfer it to the tape drive.

Except a crashing hard disc, I guess. You should really copy your personal data to a location outside your box.

Hmm... all I do is running the following script every week by cron.
| Code: |
#!/bin/bash
mount /boot/
cd /
tar --exclude=usr/portage/* --exclude=var/tmp/* --exclude=var/log/* -vpc root boot bin sbin usr home opt lib etc var | bzip2 -9 | cat > /destination/`date +"%Y%m%d"`.tar.bz2
umount /boot/
|
Each backup takes about 380M and everything important is saved. In case of hardware failure I only have to boot the livecd and restore the tar.bz2-archive into the root of my (maybe new *g*) hdd. Ok, the PC running this backups has no X etc. so the backups could be much bigger on other systems. Well, i guess the most important data to save is your world file, your /etc, your /home, if you have important data in it and maybe your kernel-config anyway. The rest is nothing an emerge world can't handle.  |
