Backup Advice please

[BrandX]

I have a Synology DS-508 with 5 1TB drives in a raid 5 configuration. I'd like to get another NAS purely as a backup device. I'd like to be able to backup all files on the "main" NAS (currently about 2.3 TB) and spend as little as possible to make that happen. Anybody got good ideas on how I can do that.

I appreciate your input.

The Synology will back up to an rsync target. You could then use Delta Copy to turn a Windows machine into an rsync target, or any Linux system.
