Does this clarify my setup?
Indeed. We still have people using the database credentials who think it’s locking or encrypting their databases somehow.
I understand, this seems to confirm what I was suggesting above, i.e. DT needs, for the first sync at least, free space on the boot drive of a size at least equal to the size of the database being synced, regardless of the space available on the volume where it was asked to be saved locally (i.e. an external drive or network volume).
I’d say yes, that’s expected.
How much free space do you have? And a 70GB is not a small database for sure, unless it’s full of media files.
