A search of the NBU Windows client's file system after completing restores show some Windows clients have a large number of .NBU files where the date and size match the completed restores.
Attached is a sample from just one Windows client, there are 270 files, some from 2015 through today totaling 120 GB:
Q: What are these .NBU files and why are they created ?
Q: Although the .NBU files are not backed up or restored, why doesn't NBU clean up these files after restore complete ?
NBU 18.104.22.168 - 1 Linux Master / 2 Linux Media servers
Restoring to NBU Windows 2019 backup clients

These are not NetBackup related file even though they bear the NBU acronym. Doing a quick Internet search, these are associated with the Nokia PC Suite synchronization software. These appear to be backups of someone's Nokia phone.
So they are NBU related files... I did the recent restores and made no selection to rename any files. The selected folder and files were restored as originally named. Yet the .NBU file exist, and not on all clients with restores. Where would that rename option be located ?
Never seen Netbackup generate .NBU, not even with that file size.
In some cases when restoring files with ACL to file systems without ACL, you get extended attribute files restored, but those files are small.
@Thomas_Anthony Have you tried to list files in the restored backup using bplist or bpflist ? This is to establish if there is a name or file size match between the restored files and those in the backup image.
How to list files backed up using the bplist or bpflist command
Thank you Team for your responses and suggestions. Since the files have been deleted I cannot review the contents. The .NBU were not present in the backup images and so were not restored with the rest of the files.
