When the Backup Photo field on the Preferences dialog is set to ON and the Backup Photo Directory field is set properly,
image files will be copied to the Backup Photo Directory just after image registration is completed, resulting in a mirroring of image files.
On how to set these, refer to Section 14.4 ( page) and Section 14.4 (
page).
Caution : The backup made by this way is only a snapshot at the time of image registration. If you will rotate or delete image files after image registration, the backup will not mirror the updating.
