View Full Version : Back up solution suggestion

I have been in the computer business since 1967 and have pondered on the
best backup solution ever since.
You have two problems to overcome:
1. Accidental loss of data due to hard drive failure
2. Loss of your PC itself due to fire, theft etc.
A RAID solution will not overcome the second scenario.
DVDs are impractical if you have a large collection (>50Gb), and I don't
believe in incremental backups unless you are super-organised.

The solution is not cheap, but then how much would it cost to replace all
your music in time and money?

Use an internal hard drive that can hold all your music and configure this
for access by Slimserver.
Use 2 identical external drives (I use Lacie 500Gb double speed (800Mb/s)
firewire).
Connect one of these to the PC give it the drive letter Z so it will not be
changed if you add any further drives.
Set up an automated daily backup from the internal drive at a time when you
don't use the PC (I us a super program from:
http://www.rdcomp.net/ezbackitup/index.php called ezback-it-up which is
free and can be configured to retain the identical structure of the disc or
directory backed up). If it's large enough you might as well back up
everything on your internal hard drives.
Leave this alone for say one week.
Each Sunday (say) remove this drive (if it's firewire it should be
hot-swappable if shut down properly) and put it somewhere in a shed or take
it to work or give it to a neighbour - get it off your premises.
Replace it with the other drive and check it's working by accessing a
directory.
Repeat the process as often as you feel comfortable with.

I'm hoping that Blu-ray or HD-DVD will solve all my backup problems!!
30Gb per disc would only need 3 discs per backup.

So add the backup script I posted yesterday, because it does guard against
stupidity :) Being stupid from time to time, I've relied on it and it's
saved my bacon.
