I honestly don’t have too much to back up, so I run one full backup job every Sunday for different directories I care about. They run a check on the directory and only back up any changes or new files. I don’t have the space to backup everything, so I only take the smaller stuff and most important. The backup software also allows live monitoring if I enable it, so some of my jobs I have that turned on since I didn’t see any reason not to. I reuse the NAS drives that report errors that I replace with new ones to save on money. So far, so good.
Backup software is Bvckup2, and reddit was a huge fan of it years ago, so I gave it a try. It was super cheap for a lifetime license at the time, and it’s super lightweight. Sorry, there is no Linux version.
It may have a lot to do with licensing royalties. Exfat was created by Microsoft and is licensed for use. So why increase the cost of the device when you can just ship it with the older system that costs nothing.
