Raid - a cautionary tale
« on: November 13, 2007, 01:27:08 pm »

Head-fi forums are on my regular round of forums to read.  It has been down for a day or two.  Here is what the forum operator has to say about their problems:

So, Benn600, got backups?

Single Point of Failure!

In this case, the RAID controller AND the backups (stored on the RAID drive itself...)

EEEEEEEEEKKKKK!   
precisely why I try to avoid additional hardware or software solutions in my data storage.
I do not trust RAID as it is just another chance for catastrophe in my opinion. I've avoided NAS as well due to a need to convert file systems since they do not natively handle NTFS. I also do not use a backup which encrypts or requires special software to expand back to a readable format.
I prefer the old KISS approach: "Keep It Simple Stupid" as it works well for me   ;D

He repeated himself in para 3

Maybe it's a Text Backup, in case you did not read it the first time..

I don't want to brag too much or something bad will happen.  YES, I have made it clear that I have several backups of important data.  That is a joke that they didn't have off-NAS backups!

My email and MySQL database are among the most important things on my server (lots of "most important things").  I have my email and database backed up three times a day to my 7TB array.  The main data is on the OS drive and backed up to my array....

lots more backups all over!

A backup isn't a backup until it's 9.8 miles away.

I had to run so I couldn't finish my post.

I keep backups in a certain offsite location and I may start storing some backups where I work...that would be a great solution.

I absolutely understand the issues involved with RAID providing a false sense of security.  Although their setup was really expensive I bet mine is more reliable!  HA!

I have used RAID in various forms for 5 years and have never had a single problem.  Nor have I had drive failures that left me without data.

Can we stop talking about this...one of these days I'm gonna say NEVERMIND, I just lost a ton of data.  No more of me saying what I just said.

My real problem is when I decide to create an Archive.  I'll take lots of documents that I really don't need anymore but I try to never delete stuff.  So I'll burn a DVD or two (or 10 for larger video projects) but I don't usually create secondary copies because I don't feel like it is justified.  The edited down version of stuff (like video) I always make a duplicate of, though.

I have!  I used RAID0 for 3 years on my production box and never lost any data.

Actually, the drive would go haywire from time to time but shutting down and rebooting would fix it.

And software RAID5 for a year in Windows XP with 10 drives, again no problems whatsoever.

And now hardware RAID6 with 16 drives and no problems at all, other than a failed drive that I promptly replaced (and have a spare now).

Not to mention other smaller uses on other machines around the house.

Not a single problem!!!!  Never any major data loss, either!  I lost some data once from a corrupted MFT (or something like that) but had created a backup just before starting the major Data Move that caused the problem (moving from one drive to another).

I guess your definition and tolerance of 'trouble' is a tad different than the rest of us.

We used to rely on Raid5 but now Raid6 everything for Audio and Video. Can't be too cautious.
