Various embodiments set forth techniques for erasure coding of replicated data blocks. The techniques include receiving, by a pre-designated node, data associated with an erasure coded strip from a first node; receiving, by the pre-designated node, a replica for a first data block; saving the replica in an erasure coded strip; and in response to a trigger condition, replacing, by the pre-designated node, the replica and at least one replica of a second data block with an error correction block.

Erasure coding of replicated data blocks

A method, device, and non-transitory computer readable medium for mirroring data, comprising, selecting, based on a plurality of data attributes, a portion of local data in a local storage device for mirroring to a remote storage device and copying the selected portion of the local data to at least one cache memory of the remote storage device. Next a determination of when a failover event has occurred in the local storage device is made, wherein the failover event comprises an event in which the local data in the local storage device is inaccessible to a client computing device when the client computing device attempts to access the local data from the local storage device. A copy of the local data from the cache memory in the remote storage device is retrieved when the failover event is determined to have occurred.
