Abstract
A method of optimizing the number and type of database backups to achieve a given RTO is provided and may include receiving a RTO and receiving a heuristic for determining an amount of unencumbered processing time. A type of next backup, (i.e., a next backup), is determined wherein the type of next backup is an incremental backup when the sum of the heuristic, and the times to: restore the latest full backup, restore zero or more incremental backups, complete a current incremental backup, and perform a full backup is less than the received RTO, else the type of the next backup is a full backup. A time to schedule the next backup is scheduled based on the received RTO being a total of an amount of time to: complete the type of next backup; rollforward zero or more transaction log records; and to restore at least one backup.
