Member Function Documentation

◆ execute()

DumpBackup::execute ( )

Do the actual work.

All child classes will need to implement this

Returns: bool|null|void True for success, false for failure. Not returning a value, or returning null, is also interpreted as success. Returning false for failure will cause doMaintenance.php to exit the process with a non-zero exit status.
