Snapshot in Disk Utility

Ok, just read it is limited to SSD APFS-formatted:

"Time Machine in macOS High Sierra stores snapshots on every APFS-formatted, all-flash storage device in your Mac or directly connected to your Mac."

But it's still potentially 500G of Snapshots in my case.

The Time machine process should be fully disclosed. Is it? It's not in Mac Help.

Thanks MacJack,

There is still some gray area.

In the description it is said: "To make sure that you have storage space when you need it, snapshots are stored only on disks that have plenty of free space. When storage space gets low, snapshots are automatically deleted, starting with the oldest. That's why Finder and Get Info windows don't include local snapshots in their calculations of the storage space available on a disk."

- Does it mean you could have thousand of Snapshot?

- Does it mean Your First Aid is going to go through all that and just seems to have frozen? Because First Aid block everything when you launch it, even with details open the system seem to be stuck.

- It seems to target all the disk available, even the external not pointed as Time Machine Disk? Is it viral??

Do we have a way to control all those Snapshots?

- erase?

- limit space on disk?

- limit numbers?

It's already the beginning of a nightmare if you have to go to Disk Utility, but this add a lot of negative.

That's my worry, following the ™ description I could have 500Gb of SnapShots and on the external 70Terra!!!!

Do I reach the size of a house on your scale?

In this case Disk Utility -> First Aid would be a place to avoid if you don't want to be stuck.

In a way your Lucky!

If you have a dedicated ™ external disk, like we have there is no point to save on a possible failing internal.

It's only beneficial in case of bad update, without ™ and external disk.

So it's bells and whistle in a back box...?!
