Being a computer professional, I could not rely on a single pc. PC's are not like cars - If your car breaks, you take it to the garage and get a spare car until your car is fixed. If your pc breaks, you might have to buy a new one. So I wanted a solution with a spare pc, which became my video converting and backup pc.
I connected them with 2 GigaEthernet adapters and use the free Karen's Replicator (
http://www.karenware.com) to backup my 80GB D: Drive (with all user und media data) to a 120GB R: Drive (Replica-Drive) on the second pc. This is totally automated and very, very fast!
If PC 1 crashes I can immediately switch to PC 2, redirect the home directory and continue working (downtime: < 3 minutes).
For absolute security. I will need to have a second 120 GB disk on pc 2 in a caddy, so it can be stored off-site.
Advantages:
1) No more hassles with backup/restore progams
2) No more hassles with backup on cd's
3) No need for a dvd writer
4) No need for Raid, although pc 1 has Raid 1 right now.
5) Backup PC up in a couple of minutes.
6) No more hassles with WinXP restore
7) No waste of disk space because of Raid
8 ) No hassle if Raid Controller should fail
9) Background jobs (like video converting) on backup pc
10) Remote control with VNC of backup pc.
Although hd-caddy and off-site disk not yet implemented - carefree pc life!
About Raid: Still have Raid 1, but after plenty of thinking and talk with other home network cracks, came to the conclusion that Raid is not an optimal solution in a home network for 2 reasons:
1) Human error is duplicated on the mirrorerd disk
2) Raid controller crashes may make both disks unusable, so that it still needs an expensive backup strategy (either tape or messy cd's/dvd's.
Of course the main disadvantage is the cost of the backup pc, but compared to other backup solutions it is in my opinion the best solution in term of money and time wasted.
And as an added extra: I have two subnets: the GigaLan and the InternetLan which gives extra shielding of the two pc's from the internet! I can share drives via GigaLan, but not via InternetLan!
