- Le istantanee locali (memorizzate nell'unità interna) sono bianche.
- I backup archiviati sul disco di Time Machine sono rosa.
I backup rosa sono corretti in quanto sono i tuoi veri backup. Le istantanee locali sono intese come backup temporanei e intermedi e verranno eliminate automaticamente.
Local Snapshots appear in the "Star Wars" display much like normal Time Machine backups. The main difference is they're shown in white/gray in the Timeline, not the purple of a Time Machine backup on an external volume.
Like normal Time Machine backups, Local Snapshots are usually made hourly. If your Time Machine volume is available, both are usually done at the same time, so you'll see adjacent purple and white tick marks with the same time. If the Time Machine volume isn't available, Local snapshots will continue on the same schedule, so for that period you'll only see white ones.
Also, the "contextual menu" you get on Local Snapshots doesn't allow deleting a Snapshot, or all Snapshots of selected items, as on normal backups.
