Tape is GOOD thing if you have money. For work, this is the answer and
do not look anywhere else.
Here is poor man's alternative which is better than FD.
I use following script to back up to CD-R (<$1 per 650MB, 3MB more than
enough to back up system). You may ant to back up more directories like
/var/spool
Key is to make each backed up file system to reside in different
partition so they do not go too deep (-l) into large data archive and
cache like debian mirror. getselection shall get the system back as soon
as possible.
Currently 3MB including personal CVS archive. (After tar.gz)
If someone polish this, send me a copy. (Something like "dialog"
command to select from menu etc...)
