Hey,
I am currently testing out Urbackup. For that I have a sever (Ubuntu 24.04.3 LTS, UrBackup Version UrBackup 2.5.35) and a client (also Ubuntu 24.04.3 LTS, UrBackup Client Controller v2.5.26.0).
My client is an internet client.
I managed to create and restore file backups. I also created image backups but the restore does not work. I tried it over the server web interface /click on the image backuo, then “Restore Linux Image”.
It says I have to use " TF=mktemp && wget "http://urbackupserver:55414/x?a=download_client&restore_image=1&os=linux&authkey=111111111&token=CWMAb2pLzr" -O $TF && sudo sh $TF; rm -f $TF" (servername and authkey changed).
When I run this command on the Linux machine where I want the resore I get:
Saving to: ‘/tmp/tmp.dz5MFm417g’

Feb 17 09:09:25 systemd[1]: urbackuprestoreclient.service: Failed with result ‘exit-code’.
looking at the file tmp.dz5MFm417g I see that it has the entry:
#e1128bd07afd40a0a2752818730589ef
RESTORE_IMAGE=1
SERVER_NAME=“”
SERVER_PORT=“55415”
SERVER_PROXY=“”
RESTORE_AUTHKEY=“111111111”
RESTORE_TOKEN=“kooibqfL8P”
so the Server Name is empty. I tried putting in the server name manually but I am assuming it is being detected that I altered the file and therefore not executing.
How can I manage to succesfully restore the image?
Tank you very much!
