I need a solution

Have a 5220 netbackup appliance which acts as master and media server.

Recently upgraded to latest software, 2.6.1.1.  Also, purchased additional memory and another storage shelf, which was successfully installed.

Running along just fine, when i get a call from one of our "Networking Guys',  tracing packets for some other problems, but see an awful lot of traffic for a certain MAC addr.   And it's one - off from what's listed as the main interface for my 5220.  Not mine, I say.

Well, he assigned the mac address a name and IP number and now, when I https to it, VOILA, IPMI interface for my 5220.

How did this happen?  I looked at the back, and there is an ethernet-looking connection labelled IPMI, but there's no cable in it. 

Not causing any trouble, but I would like to know if this is something new, or somethings that's been broadcasting a while and someone just noticed it.  Besides the "solving the mystery" aspect, I do have another appliance which I might like to get IPMI going on, and would really like to know what happened here.

I ran a Phase 1 import on a migrated disk storage unit, and waited too long to do Phase 2; all the Phase 1 images have expired.  I try to re-run Phase 1, and it says the fragments already exist and are being skipped.  Running bpexpdate to un-expire the images does not work.  How do I start the import process over?

This is NetBackup 7.6.0.4 running on Windows.

Hello,

I have a backup job with 3 Windows servers. 2 of the servers were backed up successfully.

I was having issues with the 3rd server and cancelled the job.

Is there a way to start that backup job on the 3rd server without having to restart the whole job?

Hi Everyone,
              I have been reading a lot of forum discussions and documents to understand the behaviour of Netbackup for shadow copy components.

We are using shadow copy components for our DFS and file servers. Backups runs for hours to get completed.

As per my understanding, shadow copy components backs up system files, registry and all other system related data and puts in system state in BAR.
All user data, ADAM and other relative data is structured within user data.

There are different types of creating shadow copy using VSS.

1. VSS full clone
2. VSS copy on write (Differential copy)
3. Redirect on write

Does Netbackup use VSS full clone for shadow copy component?

A regular shadow copy from windows is completed within few minutes.
However, same data backup takes hours to get completed using NB. File backup gets completed soon.

Kindly help.

For Database policy configuration. I know that Default Application will created automatically when creating automatic backup.

Now My Question.

Do I need to specify backup schedules to default application backup. or it will depend on the automatic backup.

Base on my experience when creating a backup policy for database. Only the autonatic backup that I seeting up for backup windows and schedules. I am not configuring the default application backup. When the automatic backup run the default application will also run.

I need ur explanation about this, one of our customer asking for clarifications for this,

Hello Experts,

We have been planning to install vmsnapshot backups in our testing department. So we need to know whether we need to install nbu client on vcenter server.

Or just need to put vcenter credentials on Virtual machine servers? 

We would be taking snapshot backup from vmhost machine

We are using Netbackup 7.6.0.1 and OS Windows 2008 R2

Hyper-V backups including deleted blocks...

I need a solution

Hyper-V host: Windows 2012 R2 in a farm using CSV volumes, with NetBackup Client v7.6.1.1.  Storage target is MSDP on 5230 Appliance v2.6.1.1.

Before doing anything major inside the VM - Windows File Explorer (within the VM) showed 34.4 GB C: drive (which was 15.7 GB populated by Windows OS), and a 19.9 GB D: drive (which was 0.8 GB populated by NetBackup Client v7.6.1.1) - thus total disk space provisioned was 54.3 GB, and total used space was 16.5 GB.

The steps I followed:

1) I ran a test full VM backup, which saved 22 GB (clearly 5.5 GB larger than the used space).

2) I then filled up the C: drive and D: drive to near full, and took another full VM backup which saved 53.8 GB.

3) Then I deleted the temporary files, and emptied the waste basket, and ran another full VM backup, and it saved 53.8 GB again - even though total used space was back down to 16.5 GB.

4) I waited 10 hours, and ren the full VM backup again, and again it saved 53.8 GB.

5) Checked within the guest VM, and no VSS shadows are present/left-over after backups.

.

Now, I know that Hyper-V VM backups do not have the feature of ignoring 'deleted' blocks, as per VMware ESXi.

And I did have client-side de-dupe enabled on the Hyper-V host.

.

The reason I'm posting this - is because I need to find out whether:

1) This behaviour is just something that all backup admins have to live with.

2) Am I correct in thinking that the NetBackup Client side de-dupe engine has to re-evaluate/re-finger-print all the deleted blocks every time a full backup is run?

3) Is there anything that can be done from an Hyper-V admin function perspective to reclaim the deleted blocks?

4) Is there anything that can be done from within the guest OS to trigger a 'deleted block' reclaim?

5) If there is no deleted block reclaim function at the Hyper-V host layer or at the Hyper-V guest layer - then am I correct in thinking that... because NTFS is a 'scattering file system' (i.e. it does not prefer to over-write deleted blocks with new blocks) - that thus, slowly, or quickly (depending on rate of change) that at the Hyper-V host storage layer that all VMs will thus incrementally grow their 'thin' provisioned space up to the maximum size?

6) If question 5) is true, then surely this have grave implications to not only storage capacity planning, but also to Hyper-V host CPU capacity planning - because this means that all 'thin' provisioned Hyper-V VMs will grow to max provisioned, and that all this "used at least once but since deleted" space has to be re-evaluated in CPU (i.e. consumes Hyper-V guest CPU, and thus consumes Hyper-V host CPU) and finger-print RAM (inside the guest) every time a full backup is run?

Looking forward to discussing this.  :)

Helo,

I need help to install the NB VC web plugin.

I have strictly folowed the following Howto : http://www.symantec.com/docs/HOWTO102931 (I tell the same thing as in the official pdf documentation)

... I used an apache web server to host the plugin package and use an Vcenter administrator account to deploy the plugin

The installation complete successfully.

But the plugin does not appear.

I guess that i missed something ...

Plz, does someone, got an idea

Hyper-V backups with allow file recovery enabled, implications for catalog space?

April 11, 2015, 6:34 am

≪ Previous: NetBackup vCenter Web Plugin

I need a solution

Env:

Hyper-V host:  Windows 2012 R2 in a farm with CSV storage (from SAN), NetBackup Client v7.6.1.1

Hyper-V VM: Windows 2012 R2, NetBackup Client v7.6.1.1, and not many other applications installed, e.g. AV.

Master/media: Appliance 5230 v2.6.1.1, with MSDP storage unit.

.

Scenario:

1) A "full" backup of the guest VM using NetBackup Client inside the guest VM, it saves 111,000 files.

2) A "full" backup of the guest VM using Hyper-V Host layer, with 'enable file recovery from VM backup' enabled, saves 242,000 files.

3) A "full" backup of the guest VM using Hyper-V Host layer, with 'enable file recovery from VM backups' DISABLED, saves < 100 files.

.

If I use 'dir /b /s' type commands to list the contents of the C: and D: drives of the client, I can see circa 242,000 files - of which 150,000+ are in the C:\Windows folder structure.

So, each Hyper-V full VM backup with 'file recovery' enabled, causes an additional 130,000 file names to be recorded in the catalog for each full backup of each Windows VM.

.

Now, we know that the NetBackup 'catalog' sizing documentation recommends to use an average file name length of 110 bytes when estimating catalog size, which is clearly good advice, because on a bare bones Windows 2012 R2 system, the average file name length is 113.36 bytes.

.

What I'm leading to is... If a backup admin is to make wide-spread use of Hyper-V backups with 'file recovery enabled' at the Hyper-V host layer, then one will have to factor in the additional space required to 'catalog' all the additional file names that a plain client backup does not have to; because with a plain client backup at the guest layer using NetBackup Client within the guest OS, then the backup will use Shadow_Copy_Components: and System_State: which hides and abstracts the multitude of files which comprise the Windows OS.

.

So, some simple calculations, if I have 400 guest VMs running Windows and I want to be able to recovery individual files, and I have a retention of 8 weeks, and I take a weekly full, then I will need, an additional 44 GB of catalog space more than if I were to use plain client backups:

average len	113.36	bytes
full plain backup	111,745	files
full VM backup	242,027	files
difference	130,282	files
weekly full retention	8	weeks
number of clients	400	clients
total extra catalog space	46,153,556	KB
total extra catalog space	45,072	MB
total extra catalog space	44	GB

.

And I guess there's also got to be some additional overhead on the master server receiving details of an extra 52 million files (i.e. 400 clients * 130,000 file names) each week, which have to be saved within the catalog.

.

My question... Does the above seem reasonable?

Hi Team,

I am new to netbackup and in a need to change tapes used with my netbackup. The set up is as below.

Netbackup Master - Hosted on a windows server

Netbackup media - Netbackup appliance

The normal backups are going to VTLs created on NBA. The deduplication job running dudupes and write to Tapes. Now the dedup job is failing with error "insuffiecient space" . I need to replace some tapes used for dedup with new tapes, but without loosing the existing tapes data. That is in case i need a restore from the existing tapes, I should be able to do that, even thogh the new backups are going to new tapes.

Could some one explain me the complete procedure for doing this.

Thanks and regards

Shinoj
