I you have a spare disk with enough space, this will work great.
I use this method, the possibilities of both disks failing at
the same time are slim (yes it can happen). You mention a laptop
but do not say what OS it is running, I will assume it is Linux.
Dump is a great command to dump file systems to just about
anything.
I have a second disk which gets mounted as /backup and here is
a simple dump command to backup my /home partition:
This command will do a complete backup of the /home partition
writing it to a file in the /backup partition with the name
being: home.level0.epoch-2004-10-09, this is run once a week.
dump 0uf /backup/home.level0.epoch-`date +%F` /home
On a daily basis I want to backup just things that have changed
since the last full:
dump 2uf /backup/home.level2.epoch-`date +%F` /home
To restore files, you use the command restore.
dump and restore are included with Linux, for more information
on dump and restore, refer to the man pages.
BTW: dump and restore were created by BSD UNIX.
