This property improves the speed of incremental saves by creating a backup file (.bak). In Windows, copying the file data to create a backup file for large drawings takes a major portion of the incremental save time.

WARNING! In the case of a problem (such as a power failure in the middle of a save), it's possible that drawing data can be lost.
