A method for replicating data from a plurality of storage systems to a target storage system. The method implemented at the target storage system receives a replication request to replicate data from a source storage system to the target storage system, where the target storage system stores data replicated from the plurality of source storage systems. In response to the replication request, the target storage system identifies a replication resource limit associated with the data to be replicated from the source storage system. The target storage system then determines whether a replication resource requested by the replication request has exceeded the replication resource limit. The target storage system thus allows the replication resource to replicate data from the source storage system, in response to the replication resource not exceeding the replication resource limit.

System and methods for replication resource management in asymmetric secure multi-tenancy deployments in protection storage

Exemplary methods include performed by a storage system client include sending a service request to a storage system server. The methods further include in response to receiving a response from the storage system server requesting the storage system client to perform a backoff dynamically calculating a satisfaction ratio (s-ratio), determining a backoff time based on the s-ratio, and waiting for the backoff time to expire. In one embodiment, the methods further include in response to determining the backoff time has expired, resending the service request to the storage system server.
