Borg backup not working

[Mikrokupu666]

Tried to set up borg backup. Installation went fine, no errors there. Also self-check goes through without errors. The problem arises when I try to execute the backup manually on the server with 'sudo systemctl start matrix-backup-borg'. The following is from 'journalctl -xeu matrix-backup-borg.service' I am using ubuntu server running in virtualbox as my backup server my matrix server is running in another one of those too.

I have these in my vars.yml regarding borg

backup_borg_enabled: true backup_borg_location_repositories:

• ssh://myredacteduser@myredactedip/./backup_synapse backup_borg_storage_encryption_passphrase: "myredactedpassphrase" backup_borg_ssh_key_private: | -----BEGIN OPENSSH PRIVATE KEY----- myredactedsshprivatekeyintendedwith2spaces -----END OPENSSH PRIVATE KEY----- ssh -p myredactednonstandardsshport -o "StrictHostKeyChecking accept-new" -i /etc/borgmatic.d/sshkey

Can't figure out what is the problem. No errors in installation or self-check and everything seems to be correctly configured.

UPDATE: Problem is apparently related to my backup server as I managed to setup working borg backup to BorgBase. Still no idea what the problem is tho

Does the repo exist and has it been initialized?

I my suggestion for troubleshooting would be to try and run a borgmatic info from the container. to see if it exists yet.

No the repo doesn't exist yet, because it runs into an error before it can make it.

I ran 'borgmatic info' on the server and it sure doesn't exist. Which is weird, because running the playbook didn't raise any errors.

sudo apt install borgbackup on remote host (in your case it's myredactedip)
