Hi,
I have a question regarding backup restoration in case of server failure or migration.
How should I proceed to restore backups on a different server if I lose access to the original Postgresus instance? I'm currently using S3 as the storage backend, but I noticed that the objects in the bucket have randomized names, which makes manual recovery difficult.
Additionally, it seems there's no way to back up Postgresus's internal database. This feels problematic, as it prevents transferring the application from one server to another. In issue #95, it's mentioned that backing up the internal database doesn't make sense, but I respectfully disagree — I believe backing up Postgresus's internal database is just as important as backing up any other PostgreSQL database.
Could you clarify the recommended approach for restoring backups in a disaster recovery or migration scenario?
Thanks in advance!
