[CALUG] Self Inflicted Wound

[James Ewing Cottrell 3rd]

I don't think that you need to copy anything at all "off" your machine.

[1] boot a rescue Linux off a CD
[2] mount /dev/whatever /hosed
[3] cd /hosed; mkdir hosed; mv * .??* hosed
[4] reboot CD into install mode
[5] install to /dev/whatever but *without formatting*
[6] Put Humpty Dumpty back together again

Besides, if you want to save files, do it to another partition! Or to 
your second (or a USB) disk. Tapes are too expensive and slow, CDs and 
DVDs are to small (also slow). The only kind of backup that makes any 
sense is another disk.
