What I'm trying to do and why

Setup Borg Backup for the first time using Synology guide in BorgBase Docs: https://docs.borgbase.com/setup/synology/

Steps to reproduce

Followed instructions in the guide above with the exception of creating SSH keys using ssh-keygen -o -a 100 -t ed25519. If using ssh-keygen -f ./id_synology, I get a permission error when trying to initialize the repository.

SSH into Synology and ran command to initialize repository under Step 6 of the guide above:

/usr/local/bin/borgmatic init -e repokey-blake2 -c /volume1/BorgBackup/borgmatic.yml

Actual behavior

Remote: Could not create directory '/var/services/homes/user/.ssh'.

Thanks for your detailed ticket! Looking at what you've included here, it looks like your user may not have permission to create /var/services/homes/user/.ssh, and in fact /var/services/homes/user may not even exist. Is that possible? Is that the current user's home directory, or some other path? I don't see it listed in your borgmatic configuration file, so that makes me think it's not a configured source directory.

Side note: In step 6, the documentation uses out-of-date options. Instead of --create, use create. Instead of --prune, use prune. And instead of --check, use check.

Yes, it appears that /var/services/home/user does not exist when I try to navigate in SSH. I'm not sure if it is the current user's home directory. Will I need to create this folder so that Borg can access it? Am I misunderstanding the purpose of the source directory?

The directory listed in my borgmatic configuration file /volume1/somedatadir is a "real" test directory I'm hoping to backup.

Thanks for clarifying the correct syntax for the options in step 6.

Yeah, the source_directories are the directories to backup.

I'm not sure where /var/services/home/user is coming from (it's not in your configuration file), which is why I speculated it's the current user's home directory. It certainly looks like a home directory. Once you SSH in, you can try echo $HOME to get the user's home directory. If it's /var/services/home/user, then my guess there's a misconfiguration with that user, because their home directory doesn't exist!

Thanks for your response. You are correct, my home directory was misconfigured. Upon running echo $HOME, I was returned var/services/home/user. There is a setting under Control Panel -> User & Group -> User Home for "Enable user home service". Once I checked that, I ran /usr/local/bin/borgmatic init -e repokey-blake2 -c /volume1/BorgBackup/borgmatic.yml again, and the output no longer reports errors with the home directory.

Unfortunately, I'm still unable to initialize the repository:

Does the "returned non-zero exit status 2" indicate something wrong with my configuration file?

It means Borg itself has returned an error. I'm not sure what's wrong, but it might be this part of the Borg error above: "Repository has no manifest." See https://github.com/borgbackup/borg/issues/5955 for another instance of this happening. One thing you count try is adding --verbosity 2 on the borgmatic command-line to see if you get any more information about it. Or try deleting and re-adding the repository on the BorgBase side. Or, failing that, contacting the Borg project or BorgBase support. You can also try running an init command with Borg directly so as to eliminate borgmatic as the potential cause of this problem.

Looks like deleting and re-adding the repository on the BorgBase side fixed it! Maybe it was corrupted at some point when my user profile home directory wasn't properly configured. In any case, thank you very much for your help.
