Deferred replication of recovery information at site switchover

摘要

Methods, systems, and computer program products for providing deferred replication of recovery information at site switchover are disclosed. A computer-implemented method may include receiving a first copy of logged data for storage volumes of a disaster recovery (DR) partner at a remote site from the DR partner, receiving a request to perform a site switchover from the remote site to the local site, receiving a second copy of logged data for the storage volumes from a local high availability (HA) partner in response to the switchover, and recovering the storage volumes locally by applying one or more of the copies of logged data to corresponding mirrored storage volumes at the local site.

主权项

1. A computer-implemented method, comprising:
receiving, by a first node at a local site, a first copy of logged data from a second node at a remote site, the first copy of logged data corresponding to one or more storage volumes associated with the second node at the remote site; receiving, at the local site, a request to perform a switchover from the remote site to the local site; receiving, by the first node, a second copy of logged data from a third node at the local site in response to the switchover, the second copy of logged data corresponding to the storage volumes associated with the second node at the remote site; and recovering, by the first node, the storage volumes associated with the second node using one or more corresponding mirrored storage volumes at the local site.
