Abstract
Techniques reduce data recovery time of a storage system. The techniques involve: determining a plurality of service layers associated with a data recovery process of the storage system, the plurality of service layers being obtained by partitioning a plurality of services related to the data recovery process based on a data recovery order; in response to a start of data recovery in a target service layer among the plurality of service layers, determining, from at least one service layer lower than the target service layer among the plurality of service layers, at least one service unrelated to the data recovery in the target service layer; and disabling the determined service. With such techniques, unnecessary services in lower layers can be disabled during the data recovery process, and thereby the data recovery time may be reduced.
