rsync: [Receiver] mkdir "/mnt/raid" failed: Permission denied (13)

1. Make sure that the permissions are correct on the target host (root@bkp-fivemin)

2. Make sure that the folder you are targeting exists before running rsync

3. Alternatively copy the folder you want to folder to a seperate location and chown to to a user on the remote (that users has to be created first)

[root@fivemin /]# mkdir /root/etc-temp && cd /etc
[root@fivemin etc]# cp -r ./ /root/etc-temp 
[root@fivemin etc]# ssh testuser@bkp-fivemin
[testuser@bkp-fivemin /]# whoami
testuser
[testuser@bkp-fivemin /]# exit
[root@fivemin /]# adduser testuser
[root@fivemin /]# chown testuser:testuser /root/etc/
[root@fivemin etc]# rsync -rh --progress ./etc/ root@bkp-fivemin:/mnt/bkp

The error

[root@fivemin etc]# rsync -rh --progress ./etc/ root@bkp-fivemin:/mnt/bkp
