The invention relates to a
data processing technology, and discloses a
data recovery control method, a
server and storage medium. The method comprises the following steps of: a
server receiving a datarecovery request sent by the
client, then, obtaining the
IOPS of the
server cluster to which the terminal belongs and the historical value of the
throughput within the preset time, and calculating the predicted values of the
IOPS and the
throughput; judging whether the server cluster
system is busy or not according to the predicted value and a preset rule; when the
system is not busy; and according to the predicted value, calculating the
data recovery concurrency number which can be increased to adjust the
data recovery concurrency number of the server cluster, when the
system is busy, adjusting the data
recovery concurrency number of the server cluster according to a preset concurrency reduction rule, and performing data
recovery on the storage nodes related to the data
recovery request.By utilizing the method and the device, the technical problem that a large amount of IO is occupied during data recovery is solved, the normal operation of the system can be ensured, data copy loss can be prevented, and the risk of
data loss is avoided.
