APFS changes in Big Sur: how Time Machine backs up to APFS
If I read the article correctly, Time Machine's switching to something similar to overlay FS, but nested? I really hope they get it right: backup is where my tolerance for bugs is really low.<p>APFS already supports volume snapshots but not (I think) snapshot send / receive, à la zfs & btrfs. I thought that would be the logical next step. If Apple do add this or similar feature, would Time Machine have to switch its backing store yet again?<p>I've been generally happy with Time Machine's stability, but this is getting me a little worried. I guess now's a good time to looking into Arq (or similar) to replace my janky secondary backup scripts...
