Trying to see what is the best way to maintain data on 1U's with two drives. We want to know -
1) Run a RAID1 system. Hotswap is great, but backing up data is a pain. Plus, if it is hit by a hack or virus, then RAID does nothing.
2) Run one disk as primary, then use the second to run back ups; including taking an image of the primary drive. That way if it fails, we can get a quick restore. We know the downfail, in that if the drive fails, there is downtime time the restore is done.

How much downtime can you handle and how often does the content change on your server? I would run RAID 1 and also do a weekly complete backup to tape or SAN/NAS.

That's the exact same decision I just had to make and went for 1 drive and 1 backup - purely because if I get hit by a virus ( or if I'm dumb enough to delete something myself ;) ) as you say with raid you just have 2 ruined drives.
I'm interested that you are able to make a complete image of the main drive on the backup - how are you able to do this ?

Let me correct myself. Not all of the whole harddrive, but rather all the files associated with the Ensim software. The meat so to speak.

You are right on this. We looked into weekly BUs to a Maxtor Attach.

Perhaps you should add:
- RAID1 + Backup HDD
- Tape Drive
- Network Backup To HDD
- Network Backup to tape
There is so many ways to back up your system, but one thing for sure is you *gotta* have it.
IMHO if you are strapped for cash and can only choose either one of those... you should go with backup HDD and run a daily / weekly / monthly backup routine.

I like to use the backup HD scheme simply because I can keep multiple backups over any time period I choose. In addition it is smart to keep an off-site backup, so I use rsync + ssh. Rsync backups are fast and use little BW, depending on how much has changed since your last sync.
Just my 2 cents.
