Slide 7
Slide notes: The right
time to perform backups is when Users are not working on the System. So
usually this means 'after hours'. If Users are working on the System while
it is being backed up, then instances of incorrectly linked Transactions
may occur, due to the fact that many files are updated while Users work,
and a User event may affect files that are already backed up plus files
that are not yet backed up. Therefore, the only safe backup is one that is
performed while no Users are changing data or updating in the System.
