1. A computerized method of backing up clustered databases such that production backups associated with the clustered databases are restorable with near zero downtime, the method comprising:
transmitting, by a first computing device, first data indicative of a first backup request of a clustered database to a second computing device at a first point in time, the clustered database associated with an application, the clustered database including a plurality of nodes, each of the plurality of nodes including database data from a shared storage associated with the clustered database; mapping, by the first computing device, first backup staging disks to each of the plurality of nodes; adding, by the second computing device, the mapped first backup staging disks to a first backup staging diskgroup on a primary node of the plurality of nodes; mounting, by the second computing device, the first backup staging diskgroup to each of the plurality of nodes; executing, by the second computing device, one of:
a full backup from the primary node to the first backup staging diskgroup when load balancing is not configured, anda full backup from the primary node and at least one of the other plurality of nodes to the first backup staging diskgroup when load balancing is configured such that the full backup is representative of shared storage data at the first point in time; transmitting, by the second computing device, a catalog of first backup information to a database associated with the first computing device; and creating, by the first computing device, a first snapshot of the first backup staging disk, thereby backing up clustered databases such that production backups associated with the clustered databases are restorable with near zero downtime. |
