MarkD Are you still using kopia for backing up your backups with v12? If you are, what changes have you made as I don't think symlinks work with kopia
We switched to using rsync to copy the 'current' folder to another server. We then take an incremental compressed backup of that to Backblaze each night. We could use kopia there, but already had another backups tool running we just added to.
I'll share the rsync command we use, while I have tried a few times to clean it up and simplify, other version led to far more overhead due to the way rsync expands * first.
rsync -aL --delete --include='/backups/*/current/**' --exclude='wip-snapshot*' --exclude='snapshot*' --exclude='backup-sub*' --exclude='.ss*' /backups user@destination:/path
If you want to use kopia still and space wasn't an issue, rsync this way ^ to another folder outside of /backups and then use kopia on that folder. It would work well I think.
