In the current release 10.4, there is most definitely a bug in the database backup. Any column that is a timestamp is not exported as a string – it has no single-quotes around the data, therefore all restores fail.
This is causing major issues for our backups regime, please can you supply an immediate fix for this asap.
In the meantime, can you supply a previous version 10.2 or 10.3 so I can continue backups, as this is critical.
