Is there any sofware that would take a copy of the one NAS device and copy it to a second NAS device? This could be software on my PC that runs in the background whilst I'm working, or done automatically by the NAS devices themselves. I figured this way, if one goes down, I can utilise the other until it's fixed and then restore the data, a bit like a Raid array.
I was thinking if the drives were mapped I could just use some sort of Backup software to select the drives and copy. Minimal effort in the use of the software would also be of benefit, so literally one or two clicks, rather than selecting folders all the time.
I could leave the HDD's in the PC and then back up to the NAS for access from work, but the two NAS drives would be a bit more useful for me.
Can it be done, and any recommendations to software, paid of otherwise?
