I suspect that I am using samba because the cli line I use to connect is:

mount -t cifs //192.168.2.4/Backups /mnt/backups -o 
username=mick,password=mick

That connects no problem when using sudo from the cli. I can read all 
the files there and copy them back individually to my main machine. But 
if I try to copy to it, I normally use nautilus, stuff from the main 
machine to the mounted directory it is forbidden.

When I sudo grsync (I find rsync too intimidating with all those 
baffling parameters) it whips through all the files to send and about a 
quarter of them are shown in red with permission denied error 13. All 
the rest show up in black and you would think they are going over OK. 
But when I check on the backup machine none have been updated - even if 
I tell nautilus to refresh the list just in case it's missed something.

The backup machine uses PCLinuxOS so I can use its very useful admin 
tools to check the samba shares and the backup file has the password for 
mick set and its read/write permissions set. When I cli ls -l that 
backup directory all the directories are drwxrwxrwx and all the files in 
them are rwxrwxrwx.

So I have no backup facility now.

I've looked at other backup solutions but they all seem to produce an 
archive file which can only be restored in full. I need a backup from 
which I can retrieve a single file if needed.

Still baffled - sorry folks. No doubt I'm still a bear of very little 
brain. But I do appreciate all the suggestions I've received over the 
past 24 hours. Everyone seems to be bending their minds to my problem. 
No doubt it is a trivial thing, but it's beyond my minimal capabilities 
at the moment.
