Backup/restore history only

[BeJaHome]

Describe your core improvement

It would be great if you could only restore history from the database from a previous backup into the current database. For example when moving from the internal SQLite to an external MariaDB.

Current limitations

After switching database, all historical data from entities, etc gets lost. A restore now includes all entities, devices and core, also undoing eventual updates that were made since the backup that holds the history was made.

Technical benefits

Easier move from SQLite to for example MariaDB.

Additional context

Import and export features like in MS Access database program.
