What it means
Archive removes a photo from the main Google Photos view while retaining it in the library, search and albums. Trash holds an item you deleted for a limited recovery window; permanent deletion may make restoration impossible. With backup on, deleting in Google Photos can remove items from synced devices and shared areas as documented by Google. Neither Archive nor Trash is an independent backup.
A real-world example
A user wants old receipt photos out of daily memories. Archive keeps them searchable. If they move them to Trash instead and forget, the recovery window may expire before tax season.
What to do
Archive material you still need, verify you can find it, and send only unwanted items to Trash. Review a small batch before emptying Trash. Preserve independent copies of important images.
The distinction that matters
Archive is not a privacy vault; someone with account or album access can still find an item. Trash is not a long-term storage folder. The exact retention period and device effects should be checked in the current Google Photos interface. If an archived item was already in a shared album, archiving does not revoke the album audience. If deletion propagates to synced devices, restoring from Trash may be your last easy chance to reverse the mistake.
