Apple can. I can’t.
Making APFS snapshots requires special entitlements, which they’re not going to give me.

It doesn’t check integrity of the actual data though. But I care about my data.
- yehaaa 5y agoYou can use tmutil to create a snapshot. Or do you want to create an app that performs a snapshot via some API.
- Hackbraten 5y agoOne does not simply create an APFS snapshot using tmutil. Using tmutil means Time Machine creates a snapshot for me. It also conveniently earmarks the snapshot for later removal at Time Machine’s own discretion. That’s not what I want. I want to have a say in snapshot retention, not have some tool make the decision for me. Specifically, I need precise control over snapshot retention so I can maintain several off-site replicas of my backup.

Carbon Copy Cloner does this, and is made by a small independent developer. https://bombich.com/kb/ccc6/leveraging-snapshots-on-apfs-volumes https://bombich.com/kb/ccc6/leveraging-snapshots-on-apfs-vol...
- Hackbraten 5y agoThey have managed to obtain the special entitlement.

They’re one of two apps in the world who have been granted the entitlement as far as I know. The other one is Time Machine.
