Monday, August 29, 2022 TimeTec 0 Comments

It is crucial to perform maintenance for attendance photos regularly to maintain the database size for Ingress and AWDMS. Too many attendance photos will cause database size to keep on increasing tremendously and cause a backup problem if there is too much data. 

Device side
1) Please make sure you downloaded all the logs and attendance photos into your software 
2) Delete the attendance photos in the device to avoid old attendance photos being downloaded again into the database upon performing the maintenance
Go to Menu > Data Mgt > Delete Data > Delete Attendance Photo > can select Delete All or Delete by Time Range 

Software Side 
1) Backup Process: 
Please copy one folder that contains a user photo and attendance photo for backup purposes in case the administrators need to re-check the attendance photo for future usage
