If on the other hand you don't have such a resource then compression is an issue. I use the good old: tar --exclude /tmp --exclude /home/tmp czpPf <tar-ball-file-name> / to backup my laptop and then burn the tar-balls on DVD. I had to do a system restore once and from the mounted DVD you just do: tar xzpPf <tar-ball-file> and you are done. In one single DVD I can fit four system backups (one every month) but of course the process is slower when reading from the DVD so usually I keep a copy of the last backup tar-ball on the disk. F.
