Backup feature in DT3?

There does not seem to be a backup feature in the DT3 preference pane.
Can I find it somewhere else?

Version 3 still creates the backups but the preferences have been removed. It’s only an internal backup of the metadata and the index and should never replace a good backup strategy.

I agree viz backup strategy and have one in place.
As regards internal backups, the only ones I find inside my database files were those made by DT2. Therefore my question.

Version 3 should do weekly backups.

OK! Is that when you leave the database open? How does is operate when you close the db, as DT2 then made a backup.

Both version 2 and 3 create the backup after opening (if it’s overdue) or while it’s open.

That is all clear now! Thank you very much!!!
