Question

I think access databases should not be copied while a connection to them is open (.ldb locking file exists) as the copy file can be corrupt.
However will the copy file be corrupt only if a edit/add/delete is carried out while the
file is being copied. I’m thinking of situations where a connection to the database is left open all the while the client application is running.
Specifically I’m wondering about over-night backups where a user leaves on their machine overnight.

Answer 1

That should be fine.

You should be able to copy the file without any problems.

I just tested this, and if the user was in the middel of an update to a record, the new copy only has the original value of the row, not the values being edited.
