What does "Can't restore this pair — side unavailable" mean in Data Parking?
Short answer: One or both paired places can't be reached — a drive unplugged, a folder renamed, or an account signed out. Reconnect it, or pair the new location.
Data Parking remembers the two places you paired (for example, a folder on your Mac and one on your drive or a cloud account). When it reopens, one or both of those places can't be reached — a drive isn't connected, a folder was renamed, or a cloud account needs signing in again.
Reconnect the drive or account, then pick the pair again. If a folder was renamed or removed, pair the new location instead.
