Time Capsule showing backups date in pink
Local snapshots (stored on your internal drive) are white.
Backups stored on your Time Machine disk are pink.

The pink backups are correct as they are your real backups. Local snapshots are meant as temporary, intermediate backups and will be deleted automatically.

Local Snapshots appear in the &quot;Star Wars&quot; 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 &quot;contextual menu&quot; you get on Local Snapshots doesn't allow deleting a Snapshot, or all Snapshots of selected items, as on normal backups.
