Transitioning between replication sources for data replication operations, including: delaying a transition from using a first data repository as a source for data replication to using a second data repository as the source for data replication after detecting that one or more storage operations directed to the first data repository have not been replicated to the second data repository; and promoting the second data repository as the source for data replication such that storage operations received after completing the transition are directed to the second data repository.

Transitioning between source data repositories for a dataset

A method of managing host mappings for replication endpoints, the method including: identifying a target storage system replicating a source dataset of a source storage system, wherein a first host is mapped to the source dataset on the source storage system; providing, to the target storage system and in dependence upon a mapping of the first host to the source dataset, configuration information for connecting to a second host; and implementing, in response to a triggering event, a mapping of the second host to a replica dataset on the target storage system.

Transitioning between replication sources for data replication operations

A method of data loss prevention during transitions from a replication source, the method including: initiating a transition from using a first data repository as a source for data replication to using a second data repository as the source for data replication; prior to completing the transition and responsive to determining that one or more storage operations directed to the first data repository have not been replicated to the second data repository, delaying transition of the second data repository as the source for data replication; and responsive to completing the transition, promoting the second data repository as the source for data replication such that all storage operations received after completing the transition are directed to the second data repository.

Data loss prevention during transitions from a replication source

State recovery methods and apparatus for computing platforms are disclosed. An example method includes inserting, with a processor, a first instruction into optimized code to cause a first portion of a register in a first state to be saved to memory before execution of a region of the optimized code, maintaining, with the processor, a first indication of a first manner in which the first portion of the register is to be restored in connection with a state recovery after execution of the region of the optimized code, and maintaining, with the processor, a second indication of a second manner in which a second portion of the register is to be restored in connection with the state recovery after execution of the region of the optimized code.

State recovery methods and apparatus for computing platforms

Managing host definitions across a plurality of storage systems, including: creating, on a first storage system, a host definition describing a host that accesses a dataset that is replicated across a plurality of storage systems; determining whether a second storage system that the dataset is replicated across includes a definition of the host; responsive to determining that the second storage system does not include a definition of the host, copying the host definition created on the first storage system to the second storage system; responsive to determining that the second storage system does include a definition of the host: linking the host definition created on the first storage system to the definition of the host on the second storage system or retaining the definition of the host on the second storage system.

An example method includes inserting a first instruction into optimized code to cause a first portion of a register in a first state to be saved to memory before execution of a region of the optimized code; and maintaining a value indicative of a manner in which a second portion of the register in the first state is to be restored in connection with a state recovery from the optimized code.
