[Nottingham][Talk] *TODAY* 17/07/2007 1: Backups; 2: Microsoft!(Navigation Inn)

[Paul Mellors]

Shame i was working till midnight it sounded fun was had by all.

To be honest my own backup method is really simple i have 2 disks in the 
server and all i do is cp -Ru on a daily basis, for a home server nothing 
much more is needed.
