I recently updated my data storage. I installed a NAS to handle all of my storage needs. I originally tested the WD MyCloud, but that thing was a piece of crash ridden junk. After just two days, I had to return it. It was one problem after another.
To guard against power failure, the NAS, my router, and my modem are all powered by a UPS that can power the system for 90 minutes after a power failure.
I have about 150 GB of movies, 25 GB of music, 40 GB of pictures going back to the 1970's, and 30 GB of other files. The NAS is also storing the video from my security cameras. Since I am only using about 300 GB of the 4 TB I have available, my storage needs are filled for the time being, except I want to build a bot more redundancy into the system.
I am also looking for an off site backup solution. I need to be able to back up about 300 GB of data from the NAS. I want it encrypted before it leaves my house, needs to backup at least daily, and I want to keep costs low.
