Abstract
File system disaster recovery techniques provide automated monitoring, failure detection and multi-step failover from a primary designated target to one of a designated group of secondary designated targets. Secondary designated targets may be prioritized so that failover occurs in a prescribed sequence. Replication of information between the primary designated target and the secondary designated targets allows failover in a manner that maximizes continuity of operation. In addition, user-specified actions may be initiated on failure detection and/or on failover operations and/or on failback operations.

34. A disaster recovery system, comprising:
-
a plurality of logical resources, each logical resource associated with a physical resource;
logical namespace means for routing requests directed to a designated logical resource to an associated physical resource, said logical namespace means operatively coupled to each of the logical resources;
monitor means for actively monitoring one or more of the physical resources; and
recovery means for receiving notification from the monitor means that a physical resource has failed and causing the logical namespace means to substitute a designated alternate physical resource for the failed physical resource. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
