[solved] [rsync] @ERROR: chdir failed but directory exists

Hello Community,

I wrote a script one year ago which does a backup from one LUKS-encrypted device to another one. I do backups from /home, /etc, etc.

I also did a cron job about this to automatically save all my data after a period of time. And this really worked all the time. The old data still resides on my second encrypted hard disk.

Now I'm getting an error when I try to backup my /home and /root partition. rsync cannot chdir (cd I guess?) to /home/spiri. But /home/spiri is my home path and this path really exists.

Just the parent directories are getting copied without any file and not the same permissions as the original files (did rsync -a).

I found on the Internet adding "use chroot = yes" would solve the problem but this is not true for me.

I get chdir error for my /home/spiri and an empty directory for /root. Also I am running rsync as root.

Here is my config:

uid = nobody
gid = nobody
use chroot = no
max connections = 4
syslog facility = local5
pid file = /run/rsyncd.pid
address = 127.0.0.1
port = 873
# listen = 1
max connections = 1


[auto::home.spiri]
	path = /home/spiri
	comment = My home directory
	uid = root
	gid = root
	read only = true
	exclude = *
	include = ...


[auto::root]
	path = /root
	comment = Private area
	uid = root
	gid = root
	read only = true
	exclude = *
	include = ...

Re: [solved] [rsync] @ERROR: chdir failed but directory exists

Hello again,

I found this link with the same problem: https://unix.stackexchange.com/question … ory-exists

The problem is still not solved. I tried chroot which results in the same error and my read is chroot is not the option I'm searching for and I don't use SELinux.

Also I tried to install a command named 'chdir' in /usr/bin to implement the functionalities of cd (chdir == cd). Same error.

I am about to backup my system because I need to install Windows first because the installation will not work otherwise. I'm not sure how long do I wait until giving up.

If you need more information please tell me.

Is ProtectHome on in rsyncd.service?

Thank you, disabling it solves the problem.
