VMware Single File Restore Issue

创建时间: 08 10 月 2012 | 7 条评论

Hi,

    We have just upgraded to 7.5.0.3 and are currently implementing VMware backups.

We have some old NT servers that have been virtualised and we are backing them up via a VMware Intelligent policy.

I know NT is not supported, but backups are working, and we have test recovered the vmdk files / machines successfully.

The issue we have is that some of the NT servers do not have single file restore capability, but some DO !

I dont know why some machines are ok, and others not.

The machines are essentially identical from an OS etc point of view, and are backed up via the same policy.

HP-UX 11.31 ia64 Master server  (7.5.0.3)

Windows 2008 SP2 64bit vcenter server as the backup host. (7.5.0.3 client)

Vsphere 4.1 Update 2

ESX 4.1 Update 2

Vmware tools 7.7.0

VM hardware level 7

Windows NT4 SP6a

Any help would be appreciated

It very difficult to explain why something that unsupported work/don't work. Usually single item restore require a Netbackup agent running inside the VM. On those VM that don't work - test connectivity to the agent from the master server using bptestbpcd.  The tech note below explain how bptestbpcd works.

With 7.5 you can restore single files from the VMware backup utilising Vray technology. You dont need the client.

I am able to see single files in BAR for some servers, but for others single files are not visble.

if I use bplist I can see files for some, but others give me 227's. See below

% bplist -t 40 -C workingNT -s 10/08/12 09:00:00 "/*"
/Volume{1}/

%  bplist -t 40 -C NOTworkingNT -s 10/08/12 09:00:00 "/*"          
EXIT STATUS 227: no entity was found

Both clients are identical, backed up via the same policy, and backup worked ok

Thanks

What if you do :

bplist -t 40 -C NOTworkingNT -s 10/08/12 /

If that still does not return anything then retrive the image name (bpimagelist) from Netbakup and fire off this command -  what is the result.

bpflist -d 10/08/12 -client acme_123456789  -rl 999 -pt MS-Windows-NT  -option GET_ALL_FILES

Note the command if bpflist not bplist. acme_12456789 need to be replaced with the image name retrived from Netbackup.

Check these NT VM drives are not encrypted. Or compressed. Or running something weird at the volume level. Are they mirrored.? Just plain vanilla NTFS. Do not have a recovery partition etc.

You look like your at a supported level for Vmware support of NT OS.

If these are P2V VM's make sure (in the VM Guest OS):

  1. Vmware Tools installed
  2. Disable Hardware specific services
  3. Remove hardware specific software
  4. Remove orphaned hardware devices

Tip: Get overview/document your NBU environment. Run 'nbsu' and review the output.

Hi Nicolai, same thing I'm afraid.

bplist -t 40 -C NOTworkingNT -s 10/08/12 09:00:00 /   
EXIT STATUS 227: no entity was found
 

bpflist -d 10/08/12 -client NOTworkingNT_1349636672  -rl 999 -pt MS-Windows-NT  -option GET_ALL_FILES
no entity was found

bpflist -d 10/08/12 -client NOTworkingNT_1349636672  -rl 999 -pt MS-Windows  -option GET_ALL_FILES
no entity was found

Thanks - Darren

Are you sure you are using the right client name ?

Both bplist or bpflist must report somthing back.

When Netbackup doesn't find any files at all and you know backup is running it may be some FQDN/short name/DNS issue.

server.acme.com and acme is NOT the same server in Netbackup.
