Hi,
I created a backup of my production gateway and used it to restore another gateway for testing purposes. However, it seems that the tag history from the original gateway was not restored on the new one, as if the database was not copied over.
Is this behavior expected?
Thank you.
Yes, that's expected behavior. Tag history data is stored in an external database, either an off-the-shelf RDBMS (Microsoft SQL Server, PostgreSQL, MySQL, etc) or a SQLite file, if you're using our "internal" historian or on an Edge system.
A gateway backup stores your gateway's configuration, not its data. You need to synchronize that data separately.
