Many solutions are available, depending on the recovery objectives. When looking at RPO, one consideration is the cost of some data loss. A corporation may prefer having the ability to quickly perform a database restart instead of an option of no data loss. For other companies, such as financial institutions, data loss is not an option. Any transactions lost since the last backup point must be re-entered into the recovered database, if necessary by hand. Financial institutions keep multiple logs of each transaction so that they can be sure that they can reconcile each account.
