The challenge with this approach is that you need to drop the 'backup label' file into place as part of this operation, either by putting it into the snapshot after it's been taken, or by putting it into the data directory at restore time. Of course, you have to keep track of WAL anyway from the time the snapshots are taken until the restore is done, so it's certainly possible, as with all of this, it's just somewhat complicated. Certainly open to ideas on how to improve this. Thanks, Stephen
