Hi People,

I have a bit of a strange one I'm not sure how to track down - or what I did to create the problem in the first place for that matter.

I use a Task Scheduler rsync job to back up my Photostation shared folder to a secondary Synology. The statement reads;

/usr/bin/rsync -a --exclude='@eaDir' --exclude='#recycle' --exclude='.TemporaryItems' /volume1/photo/ sync@BackupNAS:/volume1/photo

In this way should the primary ever drop out, I can basically, manually failover to the secondary with minimal fuss + I have a backup. This setup has run successfully for years, previously.

I know that shared folder perms are controlled by - and within the PhotoStation app rather than Control Panel. You _can_ of course, play with the folder perms in both the DSM file manager and in ssh. I admit to sometime - somewhere in the not _too_ distant past playing with perms in either or both of the above (file mgr and ssh). But, at this point, I am stuffed if I can recall what I did. Either way, I have now ended up with the following scenario.

When the above code runs - from the Task Scheduler, I see the following results;

admin@PrimaryNAS:/volume1/photo$ ll

It seems ALL perms are getting removed on dirs "Baron" and "Kraft" with the consequent result, that every cmd attempting to execute on those 2 dirs fails with "Permission Denied". Even IF I manually reset the appropriate dir perms on both Baron and Kraft on the BackupNAS first and then re-run the Task Scheduler job from the Primary, the end result is what you see above.

Can anyone shed some light pls on what I may have done to be causing this?
