Backup The VNXe Shared Folder (CIFS File Server) Data
Dears,
What is the best way to automate the backup of the VNXe shared folder data (CIFS)?
I have a case where a tape drive is connected to one of the servers on the LAN with the VNXe storage and i need to backup the users data which are shared on the VNXe CIFS.

This is certainly a solution, but what of the elephant in the room.
It is my understanding that NDMP backup of a cifs share on a vnxe has the following limitations
- must backup entire volume/share (cannot backup a single directory or file within cifs share)
- must restore entire volume/share (cannot restore a single directory or file within cifs share)
- cannot restore to an alternate device or staorage system, data has to go back onto the same vnxe (what happens in case of disaster and one needs data immediately)
If my undertsanding is correct these are major and render NDMP as a *not* viable alternative. I would be happy if I am wrong in this assessment as I have a vnxe3100 with over 50TB of data which currently I do not have a timely backup solution. Again suggestions with this would be appreciated...

Backup Exec can selectively backup and restore files or folders.

I dont think this is a VNXe or NDMP restriction
Any “decent” NDMP capable backup software should be able to do that – backup just a subdir and do a directed restore
If your backup softwareware supports passing NDMP variables you can also exclude directories and/or files from the backup
Of course – as typical with NDMP – the restore has to be done to a device that understands the backup data format – in this case a VNXe, VNX or Celerra
I heard that some of the low-end backup software (Backup Exec?) would only let you configure a NDMP backup for the complete file system

With NDMP?

Selecting backup is not a straight forward way.
You will have to use Exclude/Include options while backing up. See the screenshot.
In the above example, i am exluding the folder 'Reju2'. And as you can see in the restore option, for the second backup set, Reju2 is not available, becase we told it to exclude it.
And for restore, you can select the folders directly.

In my earlier reply, a small correction..
Selecting backup is not a straight forward way.
Selecting source directories for backup is not a straight forward way.

We are using backupexec 12.5 and are *unable* to do selective backup/restore with ndmp. How are you doing this?

Marcoa, you posted in 2012 and we are 2015 now, what solution did you pick to backup your VNXe? I am having the same issue.

Backup using NDMP with dump as the backup type as opposed to smTape which doesn't allow for individual file restores. We have Networker and NetBackup and backup NetApp and VNX using NDMP dumps.
Minimum configuration on the VNX client in Networker
Remote User: username
Password: userpassword
Backup command: nsrndmp_save -T dump
NDMP Array Name: aka_file_server_name_or_storage_array_name
Application Information:
OPTIONS=NT
SNAPSURE=y
UTF8=y

NDMP backup functionality in VNXe systems helps simplify backup and restore operations. VNXe systems support NDMP v2-v4 over the network; two-way NDMP backup configuration (commonly referred to as direct-attach backup) is not supported. Instead, administrators configure a three-way heterogeneous backup where the tape drives are connected to a media server, also referred to as a DMA (Data Management Application) server, and the VNXe system communicates with this media server over the network.
Following figure shows a three way heterogeneous backup configuration.
The following backup and recovery products are supported by VNXe systsms.
