when doing incremental backups, i say, make sure you backup since the last
full backup ... otherwise,one day, your incremental backups will fail
and all subsquent backups will be worthless till the next full backup
- if wed's backup fail,s thur, fri, sat will not have wed's files
unless you backup the last n-days since the last full backup
stuff to backup
- put all your config files into /etc
- put all your data in /home
- put /usr/local/src in /home/local ???
- keep a copy of your "selections" in /etc or floppy for recovery
rest of the system is already backed up for you, free of charge
all over the web and is also already on your cdrom
backup scripts

if you accidentally delete stuff ... unless backup has already been done,
you will need to undelete the old fashion way
- dont delete it unless you know (100%) the files is the ones you wanna
erase
- alias rm to rm -i .. and other tricks
- undelete apps ( see undelete section )
