RAID 1

Right now I run a RAID 0 system and I got a trojan that really f*d up my system and I'm pretty sure I'm going to have to reformat. if I was runnign RAID 1 would this really help me or would the trojan just infect both drives? RAID 1 only protects from HD failure RIGHT?

Thanks in advance,
Raj
 
Exactly. That's why I use a DVD burner instead, and external HDs for my music jukebox.

External drives are safe _if_ you never attach them to an infected machine.

RAID-1 is most useful for real time backup (for example on a file or database server) and to provide minimal protection for people too lazy to do real backups.
 
This is why I do not run RAID1 along with wanting a performance increase with RAID 0 😛 I found that by copying my Data to a seperate HD and also backing/copying my RAID 0 setup to another HD it's more secure. There is no antivirus program that can protect a HD from receiving a newly created Virus that it doesn't know about.
 
well I used panda. It caught it right when I booted up after the big time crash. I think i turned it off at the really wrong time before panda got to it.

Ahh, NO. It provides redundency for mission critical machines.

real time backup == redundancy.

Any real business uses the RAID1 to keep the drives constantly in synch (call it "redundancy" or "real time backup," same meaning here) then has offline and preferably off-site backup for safety against fire, flood, theft, employee stupidity, etc.

wouldn't most "real" businesses use a Raid 5 setup?

Depends on the amount of data they have -- would you really buy a controller and 3+ drives to mirror 20 GB of data, instead of just 2 drives and the RAID1 built into most motherboards?

Remember as you add drives, the chance of drive failure increases, so a 4 drive RAID5 array is almost twice as likely to lose a drive as a RAID1 pair of drives. You wouldn't lose data, but it doubles your chance of maintenance headaches.

For most of my "business" machines, I have the system drive set up on a mirrored RAID, and a data drive set up on a RAID 5 + hot spare.
 
I agree with you. I was just pointing out that Raid 1 does not necessarily mean the admin is lazy. I run Raid 1 at my non-profit agency (cost and size are issues), but I backup to tape every night as well. 🙂

Ahh, I see -- by lazy people I meant the ones who use RAID1 as their only backup strategy, without also using a tape drive, CD/DVD burner, or external hard drive.

exactly... RAID1 is to provide redundancy due to hardware failures not software/virus infections.

Actually most companies now offer RAID controllers that do RAID 5+ or as HP/Compaq calls it ADG. This allows up to 2 drives in array to fail before you lose the array.
