Backup recovery method for large scale cloud data center autonomous operation

摘要

The present invention relates to a structure and method of a backup recovery method for autonomous operation of a large-scale cloud data center, This includes a node registration step of recognizing each of a plurality of nodes constituting a large-scale cloud data center, and collecting and storing hardware and software information of each of the nodes; An event monitoring step of collecting and analyzing hardware event logs and operating system event logs of each of the nodes in real time, and determining whether to perform backup or restoration of each node, a target, and a method; A recovery step of first backing up a backup target of the backup-needing node to a permanent memory and then backing up a second backup to a backup medium when a backup-needing node is detected; And a recovery step of restoring the node in need of restoration based on the permanent memory when the node in need of restoration is detected, and additionally restoring the node based on the backup media if the permanent memory is in an unusable state.
