if you wanna boot the XP ... you'd probably want to do a 100% full bakcup
first ... than do your daily incrementals..
- full bakcups with tools of your choice
( tar, dump, dd(discouraged), ghost, etc..
incremental backups ...
- do you want it to be a mirror or just leave it as
today.7days.tgz for incrementals ...
- use find to find the changes since the last full backup
- 2nd disk might have /Backup/year/mon/date.incrmental.tgz
rsync is good if you want a "live" copy of the master disk
but occupies lots of disk space ...
raid1 (mirror) is good if yo want a live copy and dont want ot worry about
doing anything to copy data to the other disk .. but if you erase a
project on the master, it will be erased within a few seconds on your
2nd (backup) disk too ... mirroring is bad for "backups"
for copy the XP stuff.. you need samba setup and working properly
and you'd need XPs shared exported so that debian can read it
- dont forget to turn on the kernel vfat,etc fs options
