Abstract
An improved backup utility allows the ability to maintain full backup and incremental backup log chains, even when databases which are part of a clustered database group are backed up from different database nodes and instances. In these embodiments, this is implemented by storing the backup of the databases from both primary and secondary (failover) nodes under a single backup client which is the cluster identifier. The backup is indexed against a constant database instance based on a user configured save set. In other words, regardless of which node is primary at the time of the backup, the backup is made against a constant backup instance.
