Proper Windows RAID Server Backup Procedure

Microsoft Windows server 2008 standard -...

Specs: Windows Server 2008, X2 4400
I work at a company that has about 9 HP blade servers each running a mirrored RAID hard drive array (RAID 1). I believe they sometimes backup to a NAS, but other than that their procedure is as follows
1) Remove 1 Drive from Each Server RAID Array each night and allow the new drive to rebuild each night.
2) They then take the "so called back up drives" in a padded case home each night with one of the owners.

Can someone please tell me how I should explain to the owner "in non technical terms" how detrimental and hazardous this procedure is, or do you believe that it is ok for us to be doing this. No one seems to want to listen to me because the Managed Services Provider said that this is perfectly fine. Thanks again for your input!!

Seems perfectly reasonable to me. The only question would ask is what happens to the drive that is taken home each night.

If the data on that drive is then transferred to some other media like a DVD and the drive is brought back empty ready to be re-inserted into the RAID array then that makes even more sense.

This is not my field of expertise. That said, I would comment that the amount of diligence exercised should correlate to the importance of the data being protected.

Only you and your company know the answer to that.

There are advantages to this form of off site storage but it isn't necessarily the best off site approach.

I think I'd do it a different way. Your company may well be doing what it wants though.

One problem is with the carts. They do go bad if you use them everyday.

Second is the people having access at their home. I would not let my companies data off site in personal vehicles.

I'd consider a two stage backup. One is to secure the data center. Second is to create some form of backup daily or by the hour or as your data demands. Could be tape or another server. Tapes should be tested too if used. Making tapes and never testing is silly. They should be secured in fireproof safe.

Last would be to pay for secure off site backups.

It all depends on how much you want to secure your data.

You would be surprised to know how far banks and other financial institutions go to protect data. We used to make systems and they started at 8 way redundancy.

Why did it take me over a year to phone in a problem to ATT?
