We use amanda to backup machines to the network on Mon-Thurs evening.
If you are responsible for a machine in "Possibly To Backup", please move it to "To Backup" or "Don't Backup." If you have a machine which isn't on the list, feel free to add it.
To speed the process of getting everyone backed up, you can start setting yourself up & send me a note when you get stuck. I will help people as they request my help, with preference for desktops with important data & for which people have started the process.

Everyone should figure out what they want backed up. Backing up data is very important. Backing up applications is probably a waste of time and tape, as they can usually be reinstalled easily & cleanly from scratch.
Workstations/Desktops/Servers with Linux, Windows, or OS X
Request a static IP address from Mark Seinw if you don't already have one. It will make locating your machine on the network MUCH easier. In the event he doesn't have any available, please use dyndnds to at least have a named address which the backup server will always be able to use to locate your machine.
If you have a windows machine, follow the Cygwin instructions. If you have an OS X machine, follow the Mac OS X instructions. In either case, you will have to allow amanda through your software firewall.
After the client has been installed, I will add the domain name and/or IP address of your computer & test your client. If all goes smoothly, you won't need to do anything else: it will quietly back up your machine Mon-Thurs evening.
Laptops or OS 9 Machines
These are more of a headache, as they are most likely on dynamic IP and/or a native backup client won't work. It is also a problem that they won't be on the network at midnight when the other machines are backed up & choosing another time when they are all on and unused is difficult. I therefore recommend backing up your data to one of the servers which are backed up. You can do this manually or I can help you create a script to do it periodically (if your laptop is typically on the network & unused whenever you have lunch for example). We allow rsync over ssh. This can keep duplicate copies of your documents on ARC, which will then be backed up to tape.

Notes on Disaster Recovery
If at all possible, recover as much as possible from backup tapes using AMANDA
copying files since a backup
I've done this. It is probably better to pause an image or to copy it to a new file & mount it, rather than copying files directly from the disk. To only copy files modified since a certain date, say 2006-05-09:
- touch -d 2006-05-09 2006-05-09
- find . -newer /home/knoppix/Desktop/2006-05-09 |cpio -pdumv /mnt/sda1/2006-05-09
If that is not possible or won't recover everything, Knoppix comes with dd_rescue. You can also install dd_rhelp to make imaging even easier:
- ddr_help /dev/sda1 /mnt/backup/sda1.img
Ctrl-C will gracefully break an imaging & you can resume the image merely by executiny the same command (even between system changes and restarts).
Note that copying bad sectors may take a while. Partial images can often be mounted:
- mount -o -o loop /mnt/sda1.img /mnt/loopback
Apparently, you must use losetup sometimes:
- losetup /dev/loop0 /mnt/sda1.img
- mount -o ro /dev/loop0 /mnt/loopback
