You can contact support referring the "TECH160324" and ask them for engineering
binary to protect you.
The issue doesn't affect NBU 7.0/7.0.1 GA.
It does affect 7.1 GA but binaries are available to resolve this.
Which Netbackup version you are using on vmware backup host and have you
deployed any EEBs on it.

Thanks & regards,

Subject: [Veritas-bu] VMWARE bug in NB 7.1/7.0.1
My co-worker Nate found this today:
You can find more details at the link below, but the summary is this: If you've
expanded an NTFS volume and the $BITMAP part of the MFT becomes fragmented in
the process, and you take a FlashBackup with the "Exclude unused and deleted
blocks" option Enabled in the snapshot options (which we do, at least on the
VMWARE.adhoc.TEST policy), then it will discard fragments of the $BITMAP,
thereby trashing the filesystem and, by extension, the backup.
This can be fixed by disabling the option "Exclude unused and deleted blocks"
in the snapshot options for the policy, but, based on my experience with the
VMWare server, restores will take about 2.5 times as long.
In the meantime, I'd say we'll certainly want to make sure to disable the
"Exclude unused and deleted blocks" option on all of our VMware backups ASAP.
Symantec says that this bug is patched in NetBackup for VMware 7.1.0.1.
This issue affects the following versions of NetBackup for VMware:
*NetBackup 7.1
*NetBackup 7.0/7.0.1 when certain Emergency Engineering Binaries have been
applied
