Since Wa-Wa-Da deals with important and critical information, such as account balances and transactions, any loss of data would be severely detrimental. Wa-Wa-Da has two systems in place to manage this risk: Daily backups are taken of the entire data set; and all operations are continuously mirrored on an off-site machine. As well as providing a means of recovering from any system failures, Wa-Wa-Da can also readily transfer operations to an alternative location whilst staying online.
