What does the Daily storage snapshots row in Services mean?
Short answer: It's the once-a-day record of drive usage that feeds the charts — not a backup. Green means one was taken in the last 36 hours; yellow means they've paused and self-healing is checking.
It's the once-a-day record of how much space your drives are using, which feeds Storage Studio's charts. It is not a backup and doesn't copy any files.
Green means a record was taken within the last 36 hours. Yellow means the daily records have paused; the self-healing monitor checks on this and normally gets them going again by itself. Storage Studio keeps about a year of these daily records.
