Method, device and program product for reducing data recovery time of storage system

A device for reducing data recovery time of a storage system, comprising:

• one or more processors;
• a memory coupled to at least one of the one or more processors and having computer program instructions stored therein, the computer program instructions, when executed by the one or more processors, causing the device to:
• determine 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, determine, 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
• disable the determined service.

A computer program product having a non-transitory computer readable medium which stores a set of instructions for reducing data recovery time of a storage system;

• the set of instructions, when carried out by computerized circuitry of the storage system, causing the computerized circuitry to perform a method of:
• 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.
