Snapshot Manager for Data Center operation | Description |
|---|---|
Discover assets | NetBackup Snapshot Manager discovers all the NFS export, SMB shares, and their snapshots along with some of their directory metadata from all the Access Zones the user has privileges to access or view. By default, a DELL PowerScale cluster has Single access zone known as System Access Zone and unless you have additional Access Zones, all the NFS export and SMB Shares are in this default Access Zone. The multiple access zone can be mapped to same or different Groupnet (Groupnet -> Subnet -> Pool). During discovery, the Snapshot Manager also associates the relevant SmartConnect of a pool to its NFS export or SMB share. NetBackup Snapshot Manager also discovers all the nested NFS exports and SMB shares irrespective of the depth at which they are created. Mentioned below are few examples of nested shares discovered by Snapshot Manager: ["/ifs/test_fs1", "/ifs/test_fs1/test_fs2", "/ifs/test_fs1/test_data/test_fs3", "/ifs/smb_03/test_data/dir01"] The discovered NFS export and SMB shares should have valid underlying file system path. The file system directory path should be shared by NFS export, SMB shares. |
