Hi, I use rsync via multiple scripts on a daily basis to backup and pull data from a remote server but I alwyas find a little bit annoying setting up the permissions manually to match those in my unraid. 

Default shares permissions is nobody:users 777 (drwxrwxrwx) for directories and 666 for individual files (-rw-rw-rw)

 

My current rsync command is like this:

 

rsync -rltvzh --progress --chown=nobody:users --chmod=775 remote_ip::rsync_module /mnt/user/dir

 

 

but this doesn't not produce the same output permission wise so I wonder if anyone uses rsync in a better way. Thanks

?...

rsync -avz --progress --chmod=775 remote_ip::rsync_module /mnt/user/dir
 

Explanation of Options:

-a: Archive mode. Preserves symbolic links, file permissions, modification times, and more.

-v: Verbose. Shows what’s being transferred.

-z: Compress file data during transfer for faster syncing.

--progress: Displays progress of the sync.

--chmod=775: Ensures the files have 775 permissions after the transfer.

 

Key Changes:

Removed -r because -a (archive) already includes recursion.

Removed --chown=nobody:users because it overrides file ownership. If maintaining permissions is crucial, let rsync transfer the original ownership unless there's a specific requirement to change it.

 

 

If the default share permissions on your system are nobody:users with 777 for directories and 666 for files, and you want rsync to maintain the source permissions during the transfer, here’s the corrected command:

 

rsync -avz --progress remote_ip::rsync_module /mnt/user/dir

as Rsync will already do that...

 

Explanation:

-a (archive): Ensures permissions, ownership, timestamps, and symbolic links are preserved.

-v (verbose): Shows detailed output during the transfer.

-z (compression): Compresses file data during the transfer.

--progress: Displays the transfer progress for each file.

 

Important Notes:

Default Behavior:

The -a flag ensures that rsync carries over the original file and directory permissions from the source.

Ownership (nobody:users) and default share permissions (777 for directories, 666 for files) will remain intact as long as they match the source.

No Ownership Changes:

Avoid using --chown unless you specifically need to set ownership differently during transfer.

Preserving Permissions:

If the files and directories on the source have permissions other than 777 or 666, rsync will copy them as-is.

Matching Default Share Permissions:

If you want to enforce 777 for directories and 666 for files explicitly during transfer, add

--chmod=Du=rwx,Dg=rwx,Do=rwx,Fu=rw,Fg=rw,Fo=rw

rsync -avz --progress --chmod=Du=rwx,Dg=rwx,Do=rwx,Fu=rw,Fg=rw,Fo=rw remote_ip::rsync_module /mnt/user/dir

?...

why are you adding a 755 ?
