Re: VMWARE backup failed with the backup failed to back up the requested files (6)

@IT-Infrastructu 

Before we look at the log, please give us more info.
NBU version?
VCenter version?
OS on Master/media/backup host?
(Unix is not supported as backup host)
OS on VM being backed up?

Is the problem with this VM only, or with others as well?

Has backup worked before?

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

Hi Marianne

NBU version? 7.7.2
VCenter version? - 6.7.0
OS on Master/media/backup host? - Windows 2008 R2
OS on VM being backed up? Linux cnbjlnx400 4.4.0-189-generic #219-Ubuntu SMP Tue Aug 11 12:26:50 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Is the problem with this VM only, or with others as well? - Yes only with one VM server

Has backup worked before? - Yes till yesterday it is working fine

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

@IT-Infrastructu 

Do you know why there is 23 minutes difference between Job Details and VxMS log?

Could you please upload bpbkar log where we can trace PID 8648 ?

In all honesty, I am battling to find anything useful in VxMS log.
There are these warnings and errors towards the end of the file, but I have no idea what it means. Google search of the warnings and errors find nothing.

13:20:44.0305 : vix_map_objctl:libvix.cpp:1216 <WARN> : Returning: 4208

Looking at Status Code Ref Guide for status 4208, I'm not sure how relevant this is, since the master server seems to be your media server and backup host (client):

NetBackup status code: 4208

Message: Could not send snapshot metadata or statefiles

Explanation: Snapshot metadata that is created by the client cannot be transferred on the master server.

Recommended Action: Verify the following:

  • The NetBackup client can communicate with the NetBackup master.

  • The state file location on the NetBackup client has write permission. The typical location of the NetBackup state file on the NetBackup client is as follows:

    Windows: C:\Program Files\Veritas\NetBackup\db\snapshot\<client>

    UNIX: /usr/openv/netbackup/db/snapshot/<client>

@IT-Infrastructu 

You may also want to go through the list of possible reasons for Status 6 in the Status Code Ref Guide:

https://www.veritas.com/content/support/en_US/doc/44037985-127664609-0/v15096798-127664609

See if anything is relevant here.

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

Hello,

I agree with @Marianne ,vxms logs doesn't match with the detaillled status (there is a delay of 23 minutes) did you share a snip of logs of a first retry and detailled status of the second?

I can see that you used san, did you try with nbd?

please share bpbkar logs.

what are types of Filesystem on the vm ?

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

Just a long shot here, but how full is your TEMP space?

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

I ahve cleared all teh files in Temp folder

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

I Have tried clearing the path and initiated the backup but again it got failed with same error

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

The location has full permission access

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

bpbkar form master and media server correct?

 

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

root file system

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

@IT-Infrastructu  bpbkar from backup host backup host cnbjbup11 (which seems to be the media server as well).
So, the same server where you collected VxMS log.

When you upload the log, please post Job Details of a failed job from the same date.

About filesystem - the question was about the Linux filesystem TYPE. e.g. ext4, XFS, etc.

Re: VMWARE backup failed with the backup failed to back up the requested files (6)

One thing to ask/check - the NBU version and VMware versions you mention are not compatible/supported (assuming you listed them correctly). VMware 6.7 was only supported when NBU 8.1 came out. Now you do mention that the vCenter version is 6.7 which may mean you have a supported vSphere version in use - but something else to check.

Did the VM team by chance recent;y upgrade VMware?

The issue yuou are seeing may be some boundary condition you have reached on that VM that now makes it incompatible with the VDDK version that NetBackup uses.
