I am trying to do an rsync backup of my server. There are several users who store their files on the server.

My user is a sudoer (can use sudo). So I run rsync with sudo so that I can backup everything from all the users.

However, I have noticed that rsync gives some errors on directories that have a permission of d---------

Why do those folders have that permission? Also, why can't my sudo rsync command get those files and folders? If I open my file manager with sudo, it is able to browse into those folders and see all the files.

-Thanks

Post the exact rsync command please.
Is the destination a mount, or a network resource (cifs, sshfs, etc)?

that is an odd permission on a folder. the permission d---- means it is a directory with no permission. in that case i believe the only one with access is root. i believe sudo can also but i am not sure that a program run with sudo would be able to. if you are getting an error then i would say that is definitely a permission issue, that it is not able to access that folder.

to remedy this, you need to set permissions so that you have access to that folder. here is a breakdown of what you need to do...

reading that will help you understand what you are doing. for instance, as root of via sudo you would want to run something like sudo chmod -R 755 /yourfoldername so that will give root full access and everyone else (users and whoever) would get read/execute access to the directory.

Ok, my script is:

rsync -azvr --no-p --no-g --chmod=ugo=rwX --delete --max-size=2048m --exclude='.Trash-0' --exclude='backintime' --exclude='guest' --exclude='lost+found' --exclude='Public' /media/md2r5/ -e ssh me@myipaddress:/home/myuserfolder/Backup

I recently added the "--no-p --no-g --chmod=ugo=rwX" to see if that'd fix it but it did not.

I use cwrsync to rsync over ssh from windows to the ubuntu server, and then this script above to backup one ubuntu server to my offsite one.
