Data recovery method, apparatus and device, and readable storage medium

A data recovery device, comprising:

• a memory, configured to store computer programs;
• and
• a processor, configured to implement, when executing the computer programs, a data recovery method comprising the steps of:
• receiving and analyzing a data recovery request sent by a monitoring node, and obtaining a total cluster data recovery amount and a total local data recovery amount;
• determining a basic recovery speed by means of the total cluster data recovery amount and the total local data recovery amount;
• performing data recovery according to the basic recovery speed, and compiling statistics on a proportion of recovered small files within a specified number of recovery periods;
• and
• adjusting the basic recovery speed by means of the proportion of the small files, and performing data recovery according to the adjusted basic recovery speed;
• wherein performing data recovery according to the basic recovery speed comprises:
• determining whether the data recovery speed in the current recovery period is greater than the basic recovery speed;
• if the data recovery speed in the current recovery period is greater than the basic recovery speed, stopping data recovery for the current recovery period;
• if the data recovery speed in the current recovery period is not greater than the basic recovery speed, continuing data recovery.

A readable storage medium, wherein the readable storage medium stores a computer program, and the computer program implements, when being executed by the processor, a data recovery method comprising the steps of:

• receiving and analyzing a data recovery request sent by a monitoring node, and obtaining a total cluster data recovery amount and a total local data recovery amount;
• determining a basic recovery speed by means of the total cluster data recovery amount and the total local data recovery amount;
• performing data recovery according to the basic recovery speed, and compiling statistics on a proportion of recovered small files within a specified number of recovery periods;
• and
• adjusting the basic recovery speed by means of the proportion of the small files, and performing data recovery according to the adjusted basic recovery speed;
• wherein performing data recovery according to the basic recovery speed comprises:
• determining whether the data recovery speed in the current recovery period is greater than the basic recovery speed;
• if the data recovery speed in the current recovery period is greater than the basic recovery speed, stopping data recovery for the current recovery period;
• if the data recovery speed in the current recovery period is not greater than the basic recovery speed, continuing data recovery.
