Abstract
A data recovery (DR) system where local backup (for example, synchronized snapshotting) is performed based on one or more recovery parameters including at least one of the following recovery data objective (RDO) type and/or recovery data block objective (RDBO) type. A recovery point objective (RPO) type parameter may additionally and concurrently used as an alternative local backup trigger.
Claims19
A computer-implemented method comprising:
- setting a recovery data objective (RDO) threshold value;
- operating a data recovery (DR) system including a first data storage sub-system and a second data storage sub-system, where:
- (i) the second data storage sub-system is located remotely from the first data storage sub-system, and (ii) data from the first data storage sub-system is replicated to the second data storage sub-system;
- during the operation of the DR system, determining that the RDO threshold value has been met;
- and
- responsive to the determination that the RDO threshold has been met, performing local backups at the first and second data storage sub-systems.
