Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] see figure 1 Shown, the present invention is a kind of multi-node rapid incremental backup method, following steps:

[0041] S000: The master server node detects the IP mark IPsign ​​in the backup record table; the master server node transmits the pre-backup signal to the slave server node;

[0042] S001: The slave server node judges and transmits the response signal according to the pre-backup signal;

[0043] S002: The master server node backs up the dat...

Abstract

The invention discloses a multi-node rapid incremental backup method. It relates to the technical field of multi-node incremental backup. Including the following steps: the master server node detects the IP mark IPsign ​​in the backup record table; the master server node transmits the pre-backup signal to the slave server node; the slave server node judges and transmits the response signal according to the pre-backup signal; the master server node backs up the data block according to the response signal ; The master server node adds the data block sequence number, sign, timestamp timestamp, and pointer to the backup record table; the master server node transfers the data block backup information to the slave server node; the slave server node backs up the data block. The invention realizes the real-time monitoring of each server node during incremental backup by setting the time stamp, mark and IP mark in the equipment backup record table and the backup record table in the server node, and solves the existing multi-node incremental backup synchronization The problem of poor performance and slow efficiency.

Description

technical field [0001] The invention belongs to the technical field of multi-node incremental backup, in particular to a multi-node fast incremental backup method. Background technique [0002] Incremental backup means that after a full backup or the last incremental backup, each subsequent backup only needs to back up the files that have been added or modified compared with the previous one. This means that the object of the first incremental backup is the added and modified files generated after the full backup; the object of the second incremental backup is the added and modified files generated after the first incremental backup files, and so on. The most notable advantage of this backup method is that there is no duplicate backup data, so the amount of data backed up is not large, and the time required for backup is very short. But the data recovery of incremental backup is more troublesome. You must have the last full backup and all incremental backup tapes (once on...
