Why is the master file backup procedure important?
Master file backup is a standard procedure in transaction processing systems to maintain master file integrity in the event that any of the following problems should occur:
1) An update program error corrupts the master files being updated.
2) Undetected errors in the transaction data result in corrupted master file balances.
3) A disaster such as a fire or flood physically destroys current master files.
If the current master file becomes corrupted or is destroyed, corporate IT professionals can retrieve the most current backed-up file from the archives and use it to reconstruct the current version of the master file.
