Hi All,

1:- Should i need NDMP license to take netbackup?

2:- we have mapped a nas drive in windows machine(Netbackup Client Installed) and one in unix(Netbackup Client Installe) so what should be the best approach to take backup?

Pls share whitepapes Best practise for CIFS/NFS share backup  

MY Environment is 

Master:- 7.0 Netbackup with windows 2008 server

Client:- one Unix machine and one windows machine.

1> It depends how you want to back it up.

If you wana use NDMP to your benifit then you have to purchase the license

NetBackup for NDMP is an optional NetBackup application. It enables NetBackup
to use the Network Data Management Protocol (NDMP) to initiate and control
backups and restores of Network Attached Storage (NAS) systems.

Symantec NetBackup for NDMP 7.5 Administrator’s Guide
http://www.symantec.com/business/support/index?pag...

Check the whitepaper :
http://www.symantec.com/connect/articles/whitepape...

2> Make sure you start the NBU client service to the same account that has got access to that NAS share and take the backup as normal windows backup.

Thanks Sazz.........

More Suggestions pls..................

So,

You will use the NDMP license when you want to backup directly from your NAS, it when you have shares using the CIFS protocol. As for mounted volumes with either NFS or SAN (FCP), you will use the normal Netbackup Client that you have in Unix machines and Windows because, for Netbackup, this volume is a local volume on server.

There are other ways to perform these backups however will depend on the technology of your storage, but in practice the aforementioned are the most used.

We do both ways here in the company, the backup via NDMP it use on our Fileserver which is mounted directly on Storage, does not have a server as an intermediary.

Dear Thiago.

Thanks for the information.

The second link is for shares backup for win 95,98, Me etc not linked with the NAS backup

Thiago Pereira's picture

But, if you do not have a NDMP license and you use to share CIFS directly from Storage, you can back up this share using a windows machine pointing to this share, like a UNC Path.

Not is the best way, but works. Only if you dont have the NDMP license.

God is the reason of my life. He bless you all.

If you are in 7.5 and have deduplication license, give a try to backup with NFS or CIFS with accelerator.

I some cases is NDMP killer...

Mark_Solutions's picture

What is your NAS device?

If it does not support the NDMP protocol then you will need to back it up via the clients attached to it as per the earlier advice

HI Mark,

My NAS device is IBM N3300

Marianne's picture

Supported NDMP devices are listed in NBU 7.x HCL: http://www.symantec.com/docs/TECH76495

Additional device-specific config info in this doc: 
NDMP Appliance Information: http://www.symantec.com/docs/TECH31885 

So, you have choice - NDMP backup to direct-attached devices or as remote client, or else via CIFS share as stated in previous excellent posts.

My Setup is as below.

MY Environment is 

Master:- 7.0 Netbackup with windows 2008 server with NDMP license.

Client:- one Unix machine and one windows machine.

NAS device:- IBM N3300 V2, V3 and V4 supported.

One standalone Tape drive is attached to Master Server.

Need to take NAS Drive backup. Pls suggest me the best way.

was going through the NAS Guide and Found three options But got confused which one suits here.
 
Backups can be conducted in any of the following ways:
 
■ NDMP local backup
 
■ NDMP three-way back up
 

■ Backup to a Media Manager storage unit on the NetBackup server 

Yasuhisa Ishikawa's picture

IBM N series is supported as NDMP device. Check HCL.

http://www.symantec.com/docs/TECH76495

Also chech NetBackup 7.0 for NDMP Administrator's Guide and NAS appliance information. These docs describes considerations and configuration steps.

To what device you ant to store backup? Local NDMP(Direct NDMP) is an option if you have tape drives directly attached to NDMP supported NAS. If you don't have, you can not do this configuration.

Yasuhisa Ishikawa's picture

Three-way NDMP is possible only if you have another NAS and it has its own tape drives. If you don't have, forget it.

Last one, Remote NDMP. Use tape drives or disks attached to media server as backup destination. I believe this is only option you can choose.

The standalone Tape drive is attached to Master Server.

OUCH!

Best to motivate for a small tape library!! 
Unless you are sure that all backups will fit onto one tape when backing up overnight or over the weekend.

I have to take approx 20 GB backup from NAS per week. So tape drive is enough.

Yasuhisa Ishikawa's picture

So what you have to do is:

  • enable NDMP on NAS. Run "ndmpd on" on NAS to enable NDMP daemon. If you want to enable NDMP after next boot time, add same statement into /etc/rc.
  • Allow NDMP access from media server. Run "options ndmpd.access" on NAS and check if NDMP access from media server if permitted. I assume NDMP access is not allowed by default on current ONTAP release, so you may need to run options ndmpd.access host=media_server_name". Please ensure to add same statement into /etc/rc. Also ensure to configure your NAS so that it can resolve media server's host name.
  • Add credential for NDMP host into NetBackup. Go [Media and Device Management]-[Credentials]-[NDMP hosts] and add NAS as NDMP host. Select 2nd option and enter user name and its password of NAS user.
  • Configure backup policy with NDMP type. Other settings are same as normal backup. Backup selection must be specified by NAS native path like /vol/vol1. One more thing; add your NAS with "NDMP,NDMP" host type.

PS: standalone tape drive is more difficult to use than any mid-range tape libraries.

Hi All,

MY Environment is 

Master server 2008 server:- 7.0 Netbackup  with NDMP license.

Client:- one Unix machine and one windows machine.

NAS device:- IBM N3300 V2, V3 and V4 supported.

One standalone Tape drive is attached to Master Server

Pls tell me what are these below from above setup.

1--NAS Filer

2:- NDMP Host

3:- NDMP Client

4:-NDMP server application

5:-NDMP server

Yasuhisa Ishikawa's picture

Well, let me see...

NAS filer which supports NDMP is simply called "NDMP Host", and we sometimes call backup target NDMP host "NDMP client". These are same instance.

"NDMP server application", I have never heard such term. "NDMP server" also never heard.
Probably, most likely thing to "NDMP server application" in backup world is "NDMP supported backup software", and "NDMP server"  sounds like "the host on which NDMP supported backup software running".

So, I guess;

1 = IBM N3300
2 = IBM N3300
3 = IBM N3300
4 = Your NetBackup master/media server software
5 = Your NetBackup master/media server host

Thanks for the information.

But I doubt NDMP host and NDMP client are same as per the Admin Guide these two should be seperate......

More Suggestions pls.

Yasuhisa Ishikawa's picture

I'm not sure with what sentence you have doubt, but the NetBackup server host which speak NDMP(protocol) to NDMP host(NAS) is also sometimes called "NDMP host". It depends on its context.

Ok Tell me one thing what is the advantage of 3 way backup of nas filer to filer?

belse's picture

One more small question.

1:- In direct attached tape drive/library in NAS can we use this drive for non ndmp backups?

2:-what about the three way backup?

3:-In remote ndmp we can use the drive for non ndmp backups right?

Marianne's picture

Have you tried to go through the NBU for NDMP manual? See link in Yasuhisa's post.

All your questions are answered in the manual. Really....

1. No.

2. Do you have more than one NAS? One with tape drive attached?

3. Yes.

Dear Marianne,

Its quite difficult to read heavy admin books like this NDMP 122 pages every time for any small issues. I always try to find my question's answers in guides before posting any question. So no offence taken and pls bear with me :) 

2:- My environment suits only remote ndmp. so answer is very big no. So, question is same :( is non ndmp backup possible in 3 way backup?

Marianne's picture

3-way NDMP backup is when you have 2 NAS devices - one with tape drive attached. 

Yasuhisa has explained this 2 days ago:  https://www-secure.symantec.com/connect/forums/nas-backup-4#comment-8560581

as per Yasuhisa: If you don't have, forget it.

Local NDMP and 3-way NDMP are both NDMP backups and cannot perform non-NDMP backups.

As per Yasuhisa's post above:

Last one, Remote NDMP. Use tape drives or disks attached to media server as backup destination. I believe this is only option you can choose.

Not sure what is still unclear?

Thanks so much Marianne.

One thing remained the advantage of 3 way backup?

Marianne's picture

I honestly believe that you have more than enough information to make a choice....

3-way NDMP could be useful when you have multiple NAS devices and limited tape drives.
