Acronis does backup NAS to local drive, but packages everything in a backup file that I assume nothing else can open so I'm locked into their software.
Hi /u/lutinopat, I just wanted to clarify the matter above. While indeed, Acronis archives are done in proprietary .tib and .tibx formats, they can be opened even using the trial of any most recent version of the software, so even if you no longer have an active license of the product you can still recover your data.
It's been like this since the very beginning.
You will get 5 year license for our software with your WD purchase. Make sure to activate it before Dec. 31 and you're golden.
