 - Server: in some cases the automatic backup could be skipped for one day after the AyaNova server was restarted or a manual backup was made; it now always runs at the next chosen [backup time](ops-form-backup.md#backup-time).
 - Server: in some cases opening a record that has since been deleted (for example from an old link) gave a server error, and a report printed for records of which some had since been deleted failed; it now shows a "not found" message, and the report prints the remaining records.
 - Server: in some cases deleting a record that is still in use elsewhere (for example a customer, unit, part or rate used on a work order, quote or PM) gave a server error; it now always says which kind of record is using it.
+- Server: the server log now records the next automatic backup time (or that automatic backup is off) each time the server starts.
