Abstract

A cluster includes cluster shared volumes and nodes. A subset of the nodes are designated as being backup proxy nodes responsible for backing up the cluster shared volumes. The cluster shared volumes are divided into groups, each group having a number of cluster shared volumes that is less than a total number of cluster shared volumes in the cluster. Generation is initiated for a particular snapshot for a number of cluster shared volumes belonging to a particular group. The backup proxy nodes backup data from the particular cluster shared volumes belong to the particular group using the particular snapshot. After the backup, the steps initiating snapshot generation and backing up are repeated until each group of cluster shared volumes has been backed up.
