I think that because APFS uses snapshots to monitor how files change over time, and APFS uses a block-level copy-on-write mechanism for files that change, time machine may be able to create smaller diffs when backing up over APFS because it only needs to store modified blocks, not entire modified files.
- top_sigrid 6y agoYes definitely. The internals of APFS offer lots of things like these that would be very benefitial for backups. So using APFS on the backup volume should increase backup speeds big time.
- aloknnikhil 6y agoThat sounds great! I have a workflow that uses a network mounted HFS+ image for Time Machine backups that are then backed up to my GDrive. Anything to reduce the incremental backup size would help this.
