Problems solved by technology

However, the current storage system does not have a method for estimating the time required to stop snapshots, so that users have no way of knowing how long it takes to stop snapshots, which affects the execution efficiency of subsequent data backup, storage, and testing processes.

Abstract

The invention provides a snapshot stop time calculation method, and the method comprises the following steps: when a target snapshot is stopped, judging whether a target snapshot has a downstream snapshot or not: if not, determining that the snapshot stop time is 0; if yes, obtaining a first bitmap of the target snapshot and a second bitmap of the downstream snapshot; determining a clear bitmap according to the bit number of each data block in the first bitmap and the second bitmap, wherein the bit number is 0 or 1; and determining snapshot stop time according to the number of copied data blocks in the clearing bitmap, the size of each data block and the clearing rate. According to the method and the device, the time required by the target snapshot from start to stop to complete stop can be accurately determined, so subsequent data backup and storage or data test operation is facilitated, and the data backup or data test efficiency is improved. The invention also provides a snapshot stop time calculation system, a computer readable storage medium and a terminal, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of storage systems, and in particular to a calculation method, a calculation system and related devices for snapshot stop time. Background technique [0002] Currently, when the stop operation is performed on a snapshot, since the operation is not completed instantaneously, the completion time is affected by the data of the target volume, the data of the downstream volumes of the target volume, and the clearing rate. However, the current storage system does not have a method for estimating the time required to stop the snapshot, so that users have no way of knowing how long it will take to stop the snapshot, which affects the execution efficiency of subsequent data backup, storage, and testing processes. Contents of the invention [0003] The purpose of the present application is to provide a calculation method, computing system, computer-readable storage medium and terminal for snapshot stop time, which c...
