rsync

rsync over network to an external hard drive. Operation not permitted (1)

I want to backup some shared folders from my synology NAS to an external hard drive on my mac. Synology offers Hyper Backup using rsync for this kind of task. Since I can't get a task setup in Hyper Backup without it complaining about different errors, I figured I would just start by nailing the plain rsync side and then worry about Hyper Backup.

So far, the sync is successful as long as my rsync module's path points to a directory located on my main drive (i.e. /Users/bpjobin/directory). If I change it to one located in /Volumes, the sync won't work and throw me a error.

rsync.conf (on my Mac)

pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsync.log


[nas_backup_test]
  use chroot = false
  path = /Volumes/Untitled                 <-- This does not work.
  #path = /Users/bpjobin/rsync_test         <-- This works.
  uid = root                                <-- Either root or bpjobin changes nothing.
  gid = wheel                               <-- Either wheel or staff changes nothing.
  list = yes
  read only = no
  write only = no
  secrets file = /etc/rsync/rsyncd.secrets
  auth users = bpjobin                      <-- User has root permissions.
  hosts allow = *

Command ran from NAS

rsync -avz files bpjobin@<ipaddress>::nas_backup_test

The error...

UPDATE

I should add that the following command work.

rsync -avz files bpjobin@<ipaddress>:/Volumes/Untitled

So the problem lies in the rsync.conf module parameters...

Solution

  • This took forever for me to figure out. The related things people mention about cron are unrelated. You need to go to Settings->General->Sharing->Remote Login click on the "i", and enable "Allow full disk access for remote users"enter image description here
