Unable to create/connect Borg-Backup repo.

I am trying to set up encrypted remote backups of my NAS but i am unable to get a repo connected via Borg backup.

I allready tried adding the keys via OMV-Gui and also did add the key to Borg using the: export BORG_RSH='ssh -i /etc/ssh/my_secure_server_key' command and still i am getting the error message:

500 - Internal Server Error Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export LANGUAGE=; export BORG_PASSPHRASE='somepassphrase'; export BORG_UNKNOWN_UNENCRYPTED_REPO_ACCESS_IS_OK=yes; /usr/bin/borg init --encryption=keyfile 'ssh://user@server.com:23/./backups-folder' 2>&1' with exit code '2': Remote: Permission denied, please try again.
Remote: Permission denied, please try again.
Remote: user@server.com: Permission denied (publickey,password).
Connection closed by remote host. Is borg working on the server?

Is there some special location i have to put the keys in?

If someone has a solution i would be very thankful.

Executing that command doesn't help the plugin. I am in the middle of making environment variables better (assuming you are on omv 6.x). So, I would wait a day or two for me to have that ready.

Okay, so i saw in the other post you where saying to place the enviroment vairables into /etc/default/openmediavault-borg directory. Is that possible now or in the future version? also how would i do that if it is possible?

Thanks in advance.

Just install the latest version of the plugin (6.4). There is a Environment Variables tab.

First thing, thanks for adding that. But i can only add an variable after i added the repo as a repo is required to be selected when adding an env variable, only problem is that i am because of the variable not able to add the repo, and through that also unable to add the variable.. Any bypass to that or am i missing something?

Thanks in advance.

Unfortunately, I don't have a better way to work that. To create a new repo that requires environment variables, you will have to temporary add them to /etc/default/openmediavault-borgbackup until the repo is created.

So adding the Repo worked, but after adding the variable i cant get repo Info or do anything with the repo, it just gives an empty response..

Quote from ryecoaaron

The name should be environment variable name (BORG_RSH from your screenshot) not some random name.

name=value

Thank you very much, but now i have another Problem, the plugin spits out an Exeption. I allready tried giving the file 775 permission that did not work either.

using ssh user@server.com -p 23 -i /path/to/key works flawlessly (as root).

but from the borg plugin in the gui it still says:

PermissionError: [Errno 13] Permission denied: '/etc/ssh/openmediavault-123-sshkeyid

So i suppose there is an error with file permissions?

What is the output of: sudo stat /etc/ssh/openmediavault-123-sshkeyid

The output is:

sudo chown root:root /etc/ssh/openmediavault-123-sshkeyid and then try it again.

Allright i did that but it still gives me the Permission denied.

New stat of the file looks like:

stat /etc/ssh/openmediavault-openmediavault-123-sshkeyid

6.4.1 in the repo. This allows you to create environment variables for repo creation by selecting "Repo creation" for the repo.

Chmod 664 did not fix it.

And i am unable to delete the old enviroment variable, it throws out an error 500:

500 - Internal Server Error Failed to execute XPath query '//services/borgbackup/repos/repo[uuid='123-123-123-123-123']'.

I need to fire my tester (me) : ) 6.4.2 is in the repo.

I'm not sure what else it could be. I haven't used remote repos like this hardly at all.

So, deleting the Enviroment variables is working now.

The strange thing is it worked first when puting the variable in /etc/default/openmediavault-borg.

(now that doesnt work anymore)

Is it important that i dont use the default user and made a new with sudo and omv-admin groups?

Could the cause be that i add the keys by using nano /etc/ssh/keyname ?

What exactly do you mean by that?

And could it play a role that the key is in /etc/ directory? should i put it in a different one?

How do you put the keys on the server? Via OMV-Gui ( System > Certificates > SSH), via manually pasting them in the file? or via generating them on the NAS first?

I want to get my backups working finally so i can start using my nas..
