How to restore specific file from VADP VM Backup?

Yes - see NetBackup for VMware Administrator's Guide
 page 157 onwards.

Yes it is supported for most of popular guest VM OSes, but not all of them.

And it is supported for most of the popular file systems, but not all of them.

The limitations are typically VMware based, and not NetBackup based.  In fact NetBackup enhances the functionality with some great stream handlers.

At this stage we cannot say for sure whether it will be supported with your configuration/environment, because you have not supplied any version details at all.

This doc will help you:

DOCUMENTATION: Support for NetBackup 7.x in virtual environments.

https://www.veritas.com/support/en_US/article.000006177

.

If you are not comfortable with ratifying your interoperability matrices then tell us:

- NetBackup Master Server, exact OS family/version/patch, and exact NetBackup version.

- NetBackup Media Server, exact OS family/version/patch, and exact NetBackup version.

- NetBackup VMware Backup Host, exact OS family/version/patch, and exact NetBackup version.  (FYI this role is typically performed by a NetBackup Media Server, but maybe you have a NetBackup Enterprise Client performing this role?)

- Target storage type?  Tape or disk?  If "disk" then which type of NetBackup "disk storage unit"?

- VM guest, exact OS family/version/patch level, and exact file-system type and version and "bitness" (i.e. 32-bit file system, or 64-bit file system).

- ESXi host vSphere version, major version, update and patch level.   (yes all three pieces of the "version" of ESXi please!).

.

If you can supply the detail above, then one of us should be able to confirm compatibility for you.

.

Only once we have confirmed compatibility can you/we then begin to cover how to do it.

HTH.

Thanks for the reply Marianna & sdo,

I found that for some VM's backup If i go to BAR GUI & select backup type as normal it shows all files data like traditional backup & also shows Vm's vmdk data if selecet policy type as vmware.

However for some of the Vm's normal backup doesnt shows but shows only vmdk data.

I also noticed that Vm's which shows both normal & vm backup has nbu client installed on it.

But if thats the only reason I dont understand.I am new to the VM backups.

Please help..

You need to have a look at the backup policy config and the doc that sdo referenced above.

Not every type of backup supports file-level restore.

As per the section of the manual that I have referenced: 

You can actually start reading up 'Restore notes and restrictions' in Chapter 10 (p. 138)

There are quite a number of notes regarding individual file restore in this section - what can an cannot be done. (Too many to copy & paste here).

Important note on p. 157:

Note: Individual file recovery is supported from full backups and from incremental
backups, as long as the Enable file recovery from VM backup policy option is
enabled.

Read through the step-by-step restore procedure starting on p. 158.

@Weshall, I don't mean to be pushy, but I've been caught out on here several times... working on why a file level restore from a VM backup was failing... only to later discover that we weren't given enough detail re "versions", and that the circumstances of support interoperability matrices (in other postings) were unsupported anyway.

What I'm trying to say is... you may end up wasting a whole heap of time trying to work something that will never work.

So, my advice would be... to confirm your version interop support before even attempting a restore/recovery.

I did gone through those pages from admin guide but could not find the answer..

please find below details.

 1)  NetBackup Master Server, exact OS family/version/patch, and exact NetBackup version.

--> NBU 7.6.1.2 / OS Linux 2.6.32-358.el6.x86_64

2) NetBackup Media Server, exact OS family/version/patch, and exact NetBackup version.

-->NBU 7.6.1.2 / OS Windows2008(6)

3) NetBackup VMware Backup Host, exact OS family/version/patch, and exact NetBackup version.  (FYI this role is typically performed by a NetBackup Media Server, but maybe you have a NetBackup Enterprise Client performing this role?)
-->backup host is the same as media server.VM backup is happening with VM intelligent polciy

4) Target storage type?  Tape or disk?  If "disk" then which type of NetBackup "disk storage unit"?
 --> Storage type is disk on Sepaton

5) VM guest, exact OS family/version/patch level, and exact file-system type and version and "bitness" (i.e. 32-bit file system, or 64-bit file system).
  
--> Red Hat Linux 5/6/7 (64-bit) /CentOS 5/6/7 (64-bit)

6) ESXi host vSphere version, major version, update and patch level.   (yes all three pieces of the "version" of ESXi please!).

--> vSphere Client 5 Build 913577

Based on what you have posted, I would say that you should be ok.

However, we're still not clear on what file system types on are inside the guest VMs.

See page 20 of this doc:

DOCUMENTATION: Support for NetBackup 7.x in virtual environments.​

http://www.veritas.com/docs/000006177

How to find file system type inside guest VM?

Have a look again at Support for NetBackup 7.x in virtual environments -  Table 11 - VMware guest operating systems supported for file-level recovery 

You will see that CentOS does not appear in the list.
Meaning CentOS is NOT supported for file-level recovery.

For some you will see something like this:

Note: File-level recovery is supported for virtual
machines that use the 32-bit version of the ext4 file
system. Support for the XFS and ext4 (64 bit) file systems
is planned for a future release.
