I'm new to Naslite - great product - love my new NAS. I've seen a few comments on the Forum about mirroring drives and backing up. The software I use may have been mentioned in the Forum before, but I did not see it, so here it is: I use Folder Clone. See
http://www.folderclone.com This is a great little program that will mirror your drives. I find it works great with Naslite. I use Folder Clone to mirror my main hard drive data to my NAS and then to mirror it again to a second, removable drive on my NAS. Now I have all the protection I need, including protection against data loss due to power failures or blips. If for some reason someone knows of problems using Folder Clone with Naslite, please accept my apologies in advance. It works for me. Its much simpler than RAID. Try the 30 day free trial. You'll need to be running Windows from the machine where Folder Clone is installed.
