A robot control apparatus includes a controller, a storage, a backup creation processor, a checksum creation processor, a comparison processor, and a preservation processor. The comparison processor compares a checksum of a current backup file created by the checksum creation processor and a checksum of a past backup file. When the checksum of the current backup file and the checksum of the past backup file are different, the preservation processor preserves the current backup file or a difference between the current backup file and the past backup file.
