I've recently setup a NAS with a 18TB HDD. While I've got another 18TB drive as a backup, it's kept off site and I'm only able to update the backup every month or so. I've got a 1TB Nvme drive to spare and I'd be surprised if I add 1TB in the time it takes me to update the backup drive so I'm thinking using that to store any changes as a second, more frequently updated backup would be a good idea incase of any failures between backups.
Is there a tool out there that could do what I'm looking for? I'm pretty new to the whole data hoarding thing but I wanna get it right and having to re-do all the work I do between backups would be a big pain. If it could be automated to update the changes weekly or even daily that would be amazing.
I do apologise if in my search I've missed the obvious and there's a tool I've completely skipped over that's exactly what I'm looking for but I do appreciate any help. I'm enjoying learning about how to keep my data safe and have some very important files I want to last to when I'm long gone.
