NFS permissions confusion

I have created a backup dataset for automated backup on servers of HTML and SQL yet I have hit a bit of a brickwall with permissions moving files over.

For some reason this has only affected the HTML backup, the SQL backup ran fine, this mysqldumps each database then gzips it afterwards. The HTML backup create tar files of each HTML directory but then failed on gzip with "Operation not permitted" I tried changing this to tar / gzip into a temp directory and moving to the backup mount, this also failed but creates a 0 byte file.

Manually I can create / put data / delete files OK, but as soon as I try to copy backup file with same name I get "Operation not permitted"

Code:
root@hqops:~# mv /tmp/backup/\[2019-05-12\]\[HXXL\]test.backup.tar.gz /mnt/backup/HQOps.d8ff.net/2019-05/
mv: cannot create regular file '/mnt/backup/HQOps.d8ff.net/2019-05/[2019-05-12][HXXL]test.backup.tar.gz': Operation not permitted

root@hqops:~# ls -al /mnt/backup/HQOps.d8ff.net/2019-05/\[2019-05-12\]\[HXXL\]test.backup.tar.gz
-rwxrwxr-x 1 dan root 0 May 12 10:17 '/mnt/backup/HQOps.d8ff.net/2019-05/[2019-05-12][HXXL]test.backup.tar.gz'
root@hqops:~# rm /mnt/backup/HQOps.d8ff.net/2019-05/\[2019-05-12\]\[HXXL\]test.backup.tar.gz

root@hqops:~# touch /mnt/backup/HQOps.d8ff.net/2019-05/\[2019-05-12\]\[HXXL\]test.backup.tar.gz
root@hqops:~# echo blah blah > /mnt/backup/HQOps.d8ff.net/2019-05/\[2019-05-12\]\[HXXL\]test.backup.tar.gz
root@hqops:~# ls -al /mnt/backup/HQOps.d8ff.net/2019-05/\[2019-05-12\]\[HXXL\]test.backup.tar.gz
-rwxrwxr-x 1 dan root 10 May 12 10:18 '/mnt/backup/HQOps.d8ff.net/2019-05/[2019-05-12][HXXL]test.backup.tar.gz'
root@hqops:~# cat /mnt/backup/HQOps.d8ff.net/2019-05/\[2019-05-12\]\[HXXL\]test.backup.tar.gz
blah blah
root@hqops:~# rm /mnt/backup/HQOps.d8ff.net/2019-05/\[2019-05-12\]\[HXXL\]test.backup.tar.gz

root@hqops:~# mv /tmp/backup/\[2019-05-12\]\[HXXL\]test.backup.tar.gz /mnt/backup/HQOps.d8ff.net/2019-05/
mv: cannot create regular file '/mnt/backup/HQOps.d8ff.net/2019-05/[2019-05-12][HXXL]test.backup.tar.gz': Operation not permitted
root@hqops:~#


* HXXL is actually HTML, just replaced afterwards to stop forum trying to insert HTML tags

I have the dataset owner set as 'dan' and the NFS mount maproot is also set as 'dan'
/mnt/backup is the FreeNAS NFS mount

Can anyone offer any pointers on whats going on?

Can you show the output of ls -l in the dir /mnt/backup/HQOps.d8ff.net/2019-05/ ?

And what about ls -l /mnt/backup/HQOps.d8ff.net/ ?

Also can you run (as root) touch /mnt/backup/HQOps.d8ff.net/2019-05/test.txt

2019-05-old and 2019-04 are backups made on old system and copied over yesterday which went fine. have tried renaming 2019-05 dir and it happily recreated OK but again stalled when gziping HTML backups (same result totally removing HQOps.d8ff.net directory, recreates it all fine but stops there).

touching files works fine...

Code:
root@hqops:~# touch /mnt/backup/HQOps.d8ff.net/2019-05/test.txt
root@hqops:~# ls -l /mnt/backup/HQOps.d8ff.net/2019-05/test.txt

This is a full backup run to show...

Code:
root@hqops:~# mv /mnt/backup/HQOps.d8ff.net /mnt/backup/HQOps.d8ff.net.old
root@hqops:~# ls -l /mnt/backup/HQOps.d8ff.net
