Abstract
Official abstract text for this publication.
A method, a device, and a system for backup are disclosed. The method includes: receiving a backup packet; analyzing the backup packet to obtain a serial number of an active data packet, where the serial number is carried in the backup packet; calculating a sum of the serial number of the active data packet and a specific increment value to obtain a serial number of a standby data packet; and backing up the serial number of the standby data packet. Therefore, after the service is switched over from the active device to the standby device, the active device still regards the data packet sent by the former standby device as a new data packet and receives the data packet, which prevents service interruption caused by the switchover and improves continuity of service processing in the process of two-node cluster hot backup.
First claim
Opening claim text (preview).
What is claimed is: 1. A backup method, executed by a first device, the method comprising: receiving a backup packet from a second device, wherein the backup packet carries a first serial number that indicates a serial number of a data packet sent by the second device to a peer device; obtaining the first serial number by analyzing the backup packet; obtaining a second serial number by calculating a sum of the first serial number and a specific increment value, wherein the spe…
