Do I need System Protection for an external HDD?

[Senator]

I have an external hard drive where I keep things like drive images, backup files (CrashPlan), offline data, etc.

I'm beginning to get concerned about available space. I ran a report using an application called TreeSize and noticed that I have a considerable amount of space (46GB) being consumed by System Volume Information, which I understand are Restore Points, A.K.A System Protection.

I'd like the use of that 46GB that is in the System Volume Information unless it will create a problem.

So do I need System Protection on the external HDD? If so, why. If not, why not.

Cheers

You shouldn't really delete it but you might set the limit to 4GB. See how HERE. Be sure to specify the drive letter of your external drive not C: .
