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.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?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...
