  • Patent number: 11860892
    Abstract: Offline building of a projected data subset may be performed. A request to create a data set that is a projected subset of data from a source data set may be received. A data store separate from the data store storing the source data set may store a copy of the source data set that is used to replicate items to the projected subset of data according to a schema for the projected data subset. Updates made to the source data set may also be replicated to the projected data subset according to the schema. Conflicts between replicated items and replicated updates to the projected data set may be resolved by comparing a version identifier for the replicated update and replicated item to determine what to store in the projected data subset.

  • Patent number: 11669543
    Abstract: The described technology is generally directed towards bulk-mode replication of data objects to a destination replication site. When replicating a group of objects, and there is enough object data to fill one or more chunk data structures, bulk-mode data replication is performed, with the destination site replicating the objects into chunk data structures and performing erasure coding to protect the data. This avoids the need for inefficient preliminary data protection scheme at the replication destination. When there are multiple objects to be replicated but not enough object data to fill a chunk data structure, bulk-mode data replication transfers the objects to the destination site for replicating as individual objects. Standard object-level replication can be used for single object replication. The technology thus facilitates high-performance data transfer to destination replication sites and efficient handling of data at the replication destination site.

  • Patent number: 11100135
    Abstract: In one aspect, data replication processes include setting a minimum snap set creation interval, a maximum snap set creation interval, and a recovery time threshold (RTT). An aspect further includes creating snap sets during a synchronous replication process based on the snap set creation intervals and the RTT. The snap set creation further includes monitoring an amount of data changes since the last snap set creation, monitoring throughput statistics between a source and target system, and estimating an amount of time to replicate the data changes to the target system based on the data changes and throughput statistics. Upon determining the time to replicate the data changes reaches the RTT and the time since the last snap set creation passes the minimum interval, the snap set creation includes creating a next snap set, storing the next snap set at the source, and replicating the next snap set at the target.
