In  order  to  make  sure  data  security  and  to  restore,  we  suggest  you  backup database in regular time, click command on the menu, pop­up  following window.

Select position to save  file,  input filename (maybe  defined  filename),  click  “Save”  button.  When  original  database  was  damage,  it  need  to  restore, you should change back up filename as ATT2000.mdb, copy the  file under attendance install directory to cover same name file, but the  action only restore these data to before back up. E.g. you back up data in  31.3, so that these data be restored are only one before 31.3.
