You use SnapVault for NetBackup to back up UNIX, Linux, Solaris, and Windows file and directory data generated by the NetBackup client.
The NetBackup GUI has two check boxes that control the type of backup mode. The first check box, the Enable Block Sharing check box, controls whether the tar image that is sent to the NearStore secondary system is aligned on the Data ONTAP block boundary for block sharing. The second check box, the File System Export check box, controls whether the unpacked file system is exported to the secondary storage system using NFS or CIFS protocols and whether backups are captured in archival Snapshot copies.
Let us suppose that you are using SnapVault for NetBackup File System Export mode for backing up UNIX, Linux, Solaris, and Windows file and directory data generated by the NetBackup client. Backed up tar images that use the File System Export mode are aligned on the Data ONTAP block boundary for block sharing. The blocks are shared through context-dependant block-sharing during the backup process. The unpacked file system is exported using NFS and CIFS protocols to allow “drag-and-drop” restore functionality, and the backups are captured in archival Snapshot copies.
For File System Export backup, you should select the Enable Block Sharing and File System Export check boxes.
