the database was slow and not responding and last time that happened, i mounted the database on a new service and it fixed the problem, but this time it didnt worked

Your Postgres service in production is currently running with its volume intact and ~1 GB of data, so the database itself is not lost. Your app services in that environment have their latest deployments torn down (REMOVED status), which is why they cannot connect to Postgres. Regarding backups, wiping a volume deletes all backups tied to it, and mounting a database on a new service creates a new, separate volume with no history from the old one - that is why the daily backups are gone.

i suspect some corrupted backup, is it possible to recover properly?

Your Postgres service is currently attached to an empty backup-restore volume, but the original volume with ~1 GB of data is still in production and unattached. You can detach the current empty volume and reattach the original one from your Postgres service's volume settings, then redeploy. Previously deleted backups are not recoverable.

i found back the backups, but the volume doesnt create properly
