Configuring Tivoli Storage Manager for NDMP operations in a NetApp clustered environment
You can back up data from a NetApp cluster to a directly attached tape device or to a Tivoli® Storage Manager server, which stores the data in a storage pool. You can back up the entire cluster to a single Tivoli Storage Manager node or parts of the cluster to multiple nodes.
About this task
- Tape device that is directly attached to a NAS file server
- You can back up data to a tape device that is directly attached to a NAS file server. This is the preferred method. Typically, it is faster to back up data to a directly attached tape device than it is to back up data to a Tivoli Storage Manager storage pool by using a network connection.
- Storage pool in the local Tivoli Storage Manager hierarchy
- You can back up data to a Tivoli Storage
Manager server, which stores the data in a storage pool of type DISK, FILE, or tape. The advantage of storing data in a storage pool is that you can replicate the data for added data protection. You can use existing storage pools or create storage pools. You must have a network connection between the NAS file server and the Tivoli Storage
Manager server. The network connection must have sufficient bandwidth to transfer the NAS backup data. Tip: This type of backup is sometimes called a filer-to-server backup.
You can use one of the following backup methods:
- Full cluster backup
- When you apply this method, the backup data of the entire cluster is owned by a single Tivoli Storage Manager node. Even if you move the volumes within the cluster, full cluster backup operations continue and you do not have to reconfigure backup operations. This is the preferred method.
- Partial cluster backup
- When you apply this method, you specify a NetApp storage virtual machine (SVM), which determines the scope of the backup operation. The SVM is a virtual server that provides access to part of a cluster. You can specify that each SVM in the cluster backs up data to a separate Tivoli Storage
Manager node. This method requires more configuration than the full cluster backup method, and it requires a network connection to transfer data from the SVM to the Tivoli Storage
Manager node.Restriction: You cannot use this method to back up data to a tape device because SVMs do not have direct access to tape devices.
