About storage lifecycle policies for snapshots
A storage lifecycle policy is a storage plan for a set of backups. NetBackup uses the lifecycle policy to determine where to store additional copies of the backup images and how long to retain those copies. In general, short-term copies can be kept on disk (for quick restore) and long-term copies can be kept on tape or other storage.
NetBackup can manage snapshot-based backups for Instant Recovery through storage lifecycle policies.. The Instant Recovery feature makes snapshots available for quick data recovery from disk. Lifecycle policies support a lifecycle storage plan for the storage unit copies that are made during an Instant Recovery backup.
