Backing up NDMP file servers to an IBM Spectrum Protect server
You can back up data to a single IBM Spectrum Protect™ server rather than attaching a tape library to each NAS device.
Procedure
To back up a server on a NAS file system, complete the following steps:
- Select an existing storage pool or set up a storage pool
for the NAS data by issuing the following command:
define stgpool naspool disk
- Define volumes to add to the storage pool. For
example, define a volume that is named naspool_volAB:
define volume naspool /usr/storage/naspool_volAB formatsize=100
- Set the copy destination to the storage pool defined previously
and activate the associated policy set.
The destination for NAS data is determined by the destination in the copy group. The storage size estimate for NAS differential backups uses the occupancy of the file space, the same value that is used for a full backup. You can use this size estimate as one of the considerations in choosing a storage pool. One of the attributes of a storage pool is the MAXSIZE value, which indicates that data is sent to the NEXT storage pool when the MAXSIZE value is exceeded by the estimated size. Because NAS differential backups to IBM Spectrum Protect native storage pools use the base file space occupancy size as a storage size estimate, differential backups end up in the same storage pool as the full backup. Depending on collocation settings, differential backups might end up on the same media as the full backup.update copygroup standard standard standard destination=naspool tocdestination=naspool activate policyset standard standard
- Set up a node and data mover for the NAS device. The data
format signifies that the backup images created by this NAS device
are a dump type of backup image in a NetApp specific format.
The NAS device is now ready to be backed up to an IBM Spectrum Protect server storage pool. Paths can be defined to local drives, but the destination that is specified by the management class determines the target location for this backup operation.register node nas1 nas1 type=nas domain=standard define datamover nas1 type=nas hla=nas1 user=root password=***** dataformat=netappdump
- Back up the NAS device to the IBM
Spectrum Protect storage
pool by issuing the following command:
backup node nas1 /vol/vol0
- Restore a NAS device from the IBM
Spectrum Protect storage
pool by issuing the following command:
restore node nas1 /vol/vol0
