Ubuntu 20.04 Client file backup will not start

client
1

Greetings,

I am running urbackup server on a windows 2019 server. All my windows servers are backing up successfully, however I have a ubuntu 20.04 server that will not start a backup at all. I have enabled debug on the the management server and the client but don’t see anything useful.

here is the client log

Where can i look for more information about what is happening here. I’ve wasted days on this and am about to throw in the towel. Windows firewall is disabled, UFW is disabled btw.

Just a thought … in the Client log is

2024-04-10 02:25:57: FileSrv: Recv Error in RecvMessage

and it appears to refer to the client settings cfg contents.
If one assumes you have NOT used the client CLI to specify what to backup - then that config should be a nice readable text file with no corruption. MAYBE an edit and write to new name, delete old, rename new to old - might help.
If one assumed that you HAVE used the the client CLI to specify what to backup - then.
I would go to the web admin interface and for this client I would click the House Icon’s once for every item I can find a House Icon for.
Then save.
Then check my backup paths chosen.

Last, I am wondering what of the (I think 4) available methods for snapshots did you choose when you installed the linux client. AND - did you download the linux client from the web admin interface - that is already/specifically configured for the client who’s checkbox you ticked OR just a vanilla download?

David,

I have tried configuring the client both ways, through the cli and through the web interface. You should know this is a fresh install of the OS. I have installed the required dependencies per the manual build method. I have tried installing the client from my management server, and i have also used the uninstall option and reinstalled via the vanilla install. The server see’s the client and adds it to the console no problem, but i can’t do file or image backups. I tried to rename the settings.cfg as you suggested but it has not made a difference.

I have tried all the options for image backup but am currently using option 4 as per the blog post i found here (https://blog.urbackup.org/). I would be happy with a file backup at this point but would prefer full image backup if possible.

When you use the web interface and the settings tab…you have the client pull-down.
I assume you pulldown and select your client…let’s call it BARF.
now we have various headings for this client… interesting are the file and image headings.

As testing will be much quicker…I suggest that you (temporarily)exclude image backups via the 2 tick boxes at the top of the image backups page.

Now to the file backups page. Towards the bottom there is a box for what to backup. I suggest you type /etc
and nothing else.
Save
Goto leftmost page (status) locate your client and use the pulldown arrow and choose full file backup.
Quickly go to activities and see if your client is up there doing something and click the red look at log button on the right.

Read what it says.

If there was nothing …go to backups and see if you client is listed there…even failures should be listed.
Pick the most recent and read the log.

Let me know the results and I will try to help some more if you wish.
