Reply : If you save you data in the folder in pen drive which have already some data , then tally will not enable to save or back up in that folder in pen drive and ask "overwrite tally backup"
Same situation will happen when you restore the file in the folder where is some other file existed . So please use blank folder for backup or restore otherwise tally delete previous data by overwriting in same folder .
If you have downloaded free Tally.ERP 9 Reference manual and read it deeply , then you will find at the chapter of Restoring Backup, Tally solution company suggest following for smooth restoring backup.
