Export
Your only backup. This list lives on this device alone — deleting the home screen icon deletes it too. On a phone this opens the share sheet, so it can go straight to Drive or iCloud.
Records when you last ran an export — neither the share sheet nor a download reports back, so check the file is really there.
Import
Replace everything from an exported file.
Sync
Keeps this device and another in step through a private code. A convenience, not a backup — it lives in the same account as this site, so Export is still the only copy that survives losing that.
