So I’m not sure if I’m doing something wrong, or if this is just how Restic works, but I’m hoping someone can help me.
I’m backing up about 63TB of data to S3, and so far it’s going ok, but I am trying to see if I can do it in segments to avoid losing too much progress if the backup fails (internet goes out, server reboot, etc.). It’s going to take almost a month total.
One idea I had was to backup one directory at a time. I’ve got 7 directories, ranging in size from 100GB to 30TB. I started with the 100GB folder, and got it uploaded. I then added the second folder, about 600GB and started it.
What I don’t understand is that if I start with just folder1, the backup finishes in 30 seconds with accurate stats. As soon as I add folder2, it lists the files in folder1 as new and rescans them. It doesn’t upload again, so it’s faster than starting from scratch, but I want it to just mark those files as unchanged and start with folder2. Is there a way to do that?
