    The distinction you make between the master server and media server isn't quite right. What matters is the backup host, which can be the master server, a media server, or another computer. The backup must be performed with a backup host that's at NetBackup 8.1.2. We need the disk mapping that occurs during backup.

    We recently found a problem with large volumes and XFS file systems. If the volume is more than around half a terabyte, the inode values for some directories and files may exceed the largest 32-bit signed integer (2147483647). NetBackup 8.1.2 cannot process such "64-bit" indexes. They will be supported in NetBackup 8.2. This discovery is so recent that I don't think we have a TechNote on it yet. I'll create one this week.

    You can check whether this applies to your VM by running "ls -li" on the directories of any large XFS volume you may have. The first column of the output is the inode value. SFR will not work until 8.2 on any directory or its subdirectories where the index is 2147483648 or greater.
