rsync permissions update every run.

I use rsync to mirror my media library to my readyNAS 316 from my Mac mini. It's a 14TB library so examples below will only show a few lines.

I run the following:

rsync -aPvui --delete-during --delete-excluded --ignore-errors --exclude={'.Trashes*/','.fsev*/','.DS_*','.Spotlight*/','Automatically Add*/','Downloads*/'} /Volumes/Media\ Drive/ /Volumes/NAS2_Media_Server/Backup/Media --log-file=/Users/CXMS/Desktop/rsync_log2

I get no errors and so far it has done as expected with one exception; every run it indicates an update to the permissions of existing files. Nothing has changed on the original file.

Examples:

Run 1:

26350 files to consider

.d...p... ./

.f...p... .Media Preferences.plist

.d...p... Audiobooks/

.d...p... Audiobooks/Diana Gabaldon/

.f...p... Audiobooks/Diana Gabaldon/01 Outlander_ Outlander, Book 1 (Unabridged) Part 1.m4b

Run 2:

26350 files to consider

.d...p... ./

.f...p... .Media Preferences.plist

.d...p... Audiobooks/

.d...p... Audiobooks/Diana Gabaldon/

.f...p... Audiobooks/Diana Gabaldon/01 Outlander_ Outlander, Book 1 (Unabridged) Part 1.m4b

As you can see both runs are identical.

Any suggestions as to why it updates the permissions every run?

Thank you in advance for suggestions.

rsync://admin@10.0.1.20:/NAS1_Media_Server/Backup/media

Changing to this seems to work:

I am going to let it run and move some date to see what happens.

Thank you.

Are you running this on the Mac?

It looks like both source and destination are local - if so, the NAS volume is likely mapped and shared with SMB. If that's the case, Samba might be changing the permissions.

You could try enabling rsync on the NAS backup share and using admin@nas-ip-address:/Backup/media as the destination

  Yes, this runs on a Mac and the NAS share is mapped as a local drive with SMB.
  
  I can call rsync on the NAS directly with the IP address?
  Would the syntax be:
  user: password@IP_Address/Share
  Or would I need to get a key from the NAS to avoid manually entering a password?

    Yes (though technically rsync on the Mac is connecting to the rsync server in the NAS).

    No (at least not on linux). Try the command first using the syntax I gave you, and see if it solves your problem. Note that you don't have to enable password protection on the destination share (look at the rsync network settings for the share). So you might not need to enter the password at all. Also, I think the default rsync access is read-only, so you do need to go the the rsync share settings and change that anyway.
    
    If you do want to use password protection, you can use the --password-file option (if that exists on the Mac version).
