16 Repeat after me ... RAID IS NOT A BACKUP
17
18 There are many ways to do a backup - various raid forms, mirrors etc can
19 help in some (and only some) instances but only a spatially separated
20 copy of the data is relatively safe.
21
22 Have two computers? - cross backup between them. (keep an old machine as
23 a file server in the back room, start it up a couple of times a week and
24 run a backup script - can even be automated)
25
26 Have a friend/relative nearby? - take your PC over, create a backup and
27 then sync the differences across the net using rsync etc - most normal
28 people do fill up todays large disks, or have large "personal valuable
29 data" requirements.

31 You dont need to backup the whole machine, just the valuable bits
32 (configs, personal data, email archives, ...)
33
34 There are many ways to do it - if you only have one disk and no backups,
35 the data by definition is not valuable :)

37 Ive just been caught by an old 1G WD green drive failing (possibly the
38 MB's fault as the sata interface died as well - seen a few of those
39 now!) that took out the middle drive from a striped LVM. Didnt bother
40 to recover, just built a new machine from leftover bits, bought another
41 drive and rebuilt it using btrfs raid 1 on the two orignal WD 2G green
42 drives and a new WD red, and restored from backups on another machine -
43 over the years this type of event has happened a few times - you only
44 need to get burnt once to learn!.
