About NDMP support for Replication Director
Replication Director can use NDMP to back up, browse, and restore from snapshots. How you configure the backup policy determines whether NetBackup uses NDMP to create snapshots of the NAS host or volume.
When deciding whether to use NDMP consider the following aspects:
Table: Comparison of NDMP or non-NDMP policy types
Functionality | NDMP | Non-NDMP |
|---|---|---|
Policy type |
| Standard or MS-Windows (Do not enable NDMP Data Mover.) |
Install NetBackup client software on the protected system | No | Yes |
Mount snapshot for backup | No | Yes |
Backup performance | Generally faster than NFS or CIFS, especially for many small files. | Generally slower than NDMP, but often faster for fewer, larger files. |
Indexing of snapshots* | Yes | Yes. Use the Index From Snapshot operation in the SLP for the policy. |
Restore capabilities | Can restore only from the NAS device. | Can restore files from any snapshot location. |
Restore view of data | Filer view: All data on the filer is protected and available for restore from a given backup. | Host view: Only data belonging to a specific protected client is available for restore from a given backup. |
*An indexed snapshot is useful in restore situations. Indexing is performed by the Index From Snapshot operation in an SLP. | ||
