Problems solved by technology

Since the data backup process will affect application performance and is very time-consuming, data backups are usually scheduled to be performed when the system load is light (such as at night)
Therefore, traditional methods are time-consuming and labor-intensive, delaying work progress
In recent years, in order to save storage space, full and incremental backup technologies are usually combined. Although the backup time is shortened and the work progress is accelerated, the full and incremental backup technologies are weak and robust to data loss or system disasters. poor sex

Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The invention provides a data backup method. refer to figure 1 As shown, it is a schematic flowchart of a data backup method provided by an embodiment of the present invention. The method may be performed by a device, and the device may be implemented by software and / or hardware.

[0041] In this embodiment, the data backup method includes:

[0042] S1. Obtain the source data to be backed up, create a snapshot volume through the copy-on-write snapshot technology, perform source data backup, generate backup data, and judge whether the backup is performed normally at all times.

[0043] In a preferred embodiment of the present invention, the copy-on-write snapshot technology (copy-on-write, referred to as COW) is about a fully available copy of the source data to be backed up, and the copy includes correspondi...

Abstract

The invention relates to a cloud storage technology, and discloses a data backup method, which comprises the following steps of: obtaining source data to be backed up, establishing a snapshot volume by utilizing a snapshot copy-on-write technology, executing source data backup and generating backup data; when backup cannot be carried out normally, invalid source data to be backed up are obtained,and the backup data are recovered through the MongoDB backup technology; and obtaining a full database backed up by the user in a preset period, and realizing database-level incremental log backup through MongoDB incremental backup. The invention further provides a data backup device and a computer readable storage medium. According to the invention, efficient backup of the source data is realized.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a data backup method, device and computer-readable storage medium. Background technique [0002] In recent years, computer technology has made great progress, but data backup technology has not made great progress. The cost and cost of data backup operations are still relatively high, and consume a lot of time and system resources, and the recovery time objective and recovery point objective of data backup are relatively long. Traditional data backup technologies have always used technologies such as data replication and recovery to protect important data information, and regularly back up or replicate data. Since the data backup process will affect application performance and is very time-consuming, data backup is usually scheduled to be performed when the system load is light (such as at night). Therefore, the traditional method is time-consuming and labor-inten...
