I have had it since v 2015. I back up my C: drive once a week incrementally and do a full backup every 5 weeks. It backs up to a mirrored 1TB pair on this system along with other selected backups from other drives and that gets copied to an offline drive periodically using file synchronizer.
I pretty only have my software on C: and keep "data" on other drives because that can simply be copied using file sync. Keeping C: smaller makes images smaller. A lot of my stuff is actually spinning on more than one machine anyway (pictures, music etc) and my legacy stuff is backed up on lots of old drives.
