Should I unplug my backup drive?

post #1 of 6
Thread Starter 
Hello all

I use a 160GB, internal 3,5" SATAII unit as a backup drive.

While I'd rather leave it on, well cooled at all times, should I unplug it to prevent it getting damaged in case of a PSU failure, which my fry all my 3 HDDs at once? Or is this too rare of a case to even consider?

Edit:
Damn you, misreading.

If that were my primary concern I'd simply buy a UPS.
As always, a backup solution is only as robust as your budget and paranoia (as well as the value of your data).

There's always a chance the backup drive itself can just die randomly, too, under normal use.

Double Edit:
Mainly suggesting a UPS as you would have a decreased risk of some sort of brownout/surge taking out your device, yet it still has the chance for failure on it's own.

The chances of a PSU failure getting your hard drive are probably fairly remote...though I have seen it happen.

I should also say that I've seen drives that have sat on a shelf loose data over time. Never did find out if that was related to it not being powered for a long while though. If you backed up regularly though...that shouldn't even be a factor. The only real issue is that I don't think the connectors on drives are built with the idea of getting plugged in and out often...you might wear out the drive.

I just leave mine going...though the power setting should have the hard drive turned off most of the time anyway and only my backup VM can access it normally.

Understood. This (connector wear) and probabily other form of electrical failure due to being suddendly booted up, (or something, lol) were my main concerns.

I think I'll just leave it on... if an HDD is hard to kill by a PSU, chances are that 2 at the same time are quite rare.

I unplug mine so that if my computer ever gets hit by nefarious ransomeware, it can nuke everything internal... but it won't nuke my backups! tongue.gif

I haven't had a virus in over 10 years, but it seems like a more likely scenario than a PSU explosion or lightning strike. Regardless, same precautionary measure, so why not do it?

That is why I back up from a VM. If I got something nasty today it could not even touch my backup since the the VM with access to the drive isn't running and there is no pass through on the other VMs to the hard drives.

I need to set up way to automate the VM cycling on and doing a backup after a major change...like I got a couple new blurays this last week so I will be running another backup. Right now I have to manually start up the VM, but the backup will start automatically.

I highly suggest people to look into virtual machines...it makes life so much easier...and cheaper. It is very rare that you ever need all your MHz for one OS...my media machine is VM with a couple other VMs on the same hardware and I can still even play a lot of games on it. (as long as your hardware and software support GPU pass through it works well)
