NetBackup™ Deduplication Guide

To mount an SMB universal share using Windows Explorer

1. Log on to the Windows server, then navigate to the Map a Network Drive tool.
2. Choose an available drive letter.
3. Specify the mount path as follows:

   \\<MSDP storage server>\<id>

   For example, \\server.example.com\my-db-share

   You can find the mount path on the NetBackup web UI: Storage > Disk storage > Universal shares.

4. Click Finish.

To mount an SMB universal share using Windows command prompt

1. Log on to the Windows server, then open a command prompt.
2. Specify the mount path using the following command:

   net use <drive_letter>:\\<MSDP storage server >\<id>

   For example: net use <drive_letter>:\\<MSDP storage server >\<id>

3. Specify the mount path as follows:

   \\<MSDP storage server>\<id>

   For example, \net use \\server.example.com\my-db-share

   You can find the MSDP storage server name and the export path from the Universal share details page in the NetBackup web UI: Storage > Disk storage > Universal shares

To mount an NFS universal share

1. Log on to the server as root.
2. Create a directory for the mount point using the following command:

   mkdir /mnt/<your_ushare_mount_point_subfolder>

3. Mount the universal share using the following one of the following commands:

   • NFSv3:

     mount -t nfs <MSDP storage server>:<export path> -o rw,bg,hard,nointr,rsize=1048576,wsize=1048576,tcp,actimeo=0,vers=3,timeo=600 /mnt/<your_ushare_mount_point_subfolder>

     For example:

     mount -t nfs server.example.com:/mnt/vpfs_shares/3cc7/3cc77559-64f8-4ceb-be90-3e242b89f5e9 -o rw,bg,hard,nointr,rsize=1048576,wsize=1048576,tcp,actimeo=0,vers=3,timeo=600 /mnt/<your_ushare_mount_point_subfolder>

   • NFSv4:

     mount -t nfs <MSDP storage server> : <export path> -o vers=4.0,rw,bg,hard,nointr,rsize=1048576,wsize=1048576,tcp,actimeo=0,vers=4,timeo=600 /mnt/ <your_ushare_mount_point_subfolder>

     Note:

     If you use NFSv4 on a Flex Appliance application instance, the export path must be entered as a relative path. Do not include /mnt/vpfs_shares.

     For example:

     mount -t nfs server.example.com:/3cc7/3cc77559-64f8-4ceb-be90-3e242b89f5e9 -o rw,bg,hard,nointr,rsize=1048576,wsize=1048576,tcp,actimeo=0,vers=4,timeo=600 /mnt/<your_ushare_mount_point_subfolder>

     For NetBackup FlexScale and AKS/EKS cloud platforms, if you use NFSv4 to mount the NFS share on NFS client, you must use the relative share path without the prefix /mnt/vpfs_shares.

     For example, if the export share path is engine1.com:/mnt/vpfs_shares/usha/ushare1, use NFSv4 to mount it on client as follows:

     mount -t nfs -o 'vers=4' engine1.com:/usha/ushare1 /tmp/testdir.

   • To mount an NFS share with Kerberos based authentication for NFSv3 or NFSv4, use any of the three types of security options:

     • krb5

     • krb5i

     • krb5p

   NFSv3 with krb5:

   mount -t nfs <MSDP storage server>:<export path> -o rw,bg,hard,nointr,rsize=1048576,wsize=1048576,tcp,actimeo=0,vers=3,timeo=600,sec=krb5 /mnt/<your_ushare_mount_point_subfolder>

   NFSv4 with krb5:

   mount -t nfs <MSDP storage server>:<export path> -o rw,bg,hard,nointr,rsize=1048576,wsize=1048576,tcp,actimeo=0,vers=4,timeo=600,sec=krb5 /mnt/<your_ushare_mount_point_subfolder>

   • Use krb5 for authentication only.

   • krb5i computes a hash on every remote procedure (RPC) call request to the server and every response to the client. The hash is computed on an entire message: RPC header, plus NFS arguments or results.

   • krb5p uses encryption to provide privacy. With krb5p, NFS arguments and results are encrypted.

   krb5 provides better performance and it decreases in the following order: krb5 > krb5i > krb5p.

   You can find the mount path on the NetBackup web UI: Storage > Disk storage > Universal shares.
