Requiring full backup after changing from ext4 to btrfs

[rawtaz]

@jfayre

Now, the trouble I’m having is that Restic seems to think all files have changed when I try to backup the synology directly to b2. It’s using the existing parent snapshot.

It is probably just scanning the files again to determine what contents (if any) has changed since the last backup.

@jfayre

Is this happening because I changed filesystems?

Yes, that makes sense. You have completely different inodes etc now, for the same files.

@jfayre

If so, is there any way around this without backing up everything to b2 again using Restic?

Unless I’m missing something, restic is just scanning the files, it will not upload already uploaded blocks of data that has not changed. So it should be fine to just let it run.

Does all of this make sense? I presume you are not seeing restic actually uploading all of your files’s data anew, but what you’re seeing is that it is reading all the files without actually uploading much data (of course it will upload some metadata etc).
