How to specify ssh / sftp options for resticprofile?

[pmorch]

How do I specify a custom ssh config file in a profile?

I have backup-ssh.config containing:

Host hetzner-storage-box
    Hostname u1234.your-storagebox.de
    User u1234-sub1
    IdentityFile %d/work/hetzner-restic-repo1/ssh-miller-restic-repo-1

This works:

$ restic -r sftp://hetzner-storage-box/ -p pass-miller-restic-repo-1 --option sftp.args="-F /home/peter/work/hetzner-restic-repo1/backup-ssh.config" snapshots

How can I create a profile so that the sftp.args --option also works:

$ resticprofile -c ~/work/backup/profiles.yaml hetzner.snapshots

I've tried variations of:

hetzner: 
  repository: sftp://hetzner-backup/ 
  password-file: /home/peter/store-restic-password 
  # also tried:
  # option: "sftp.args=-F /home/peter/work/hetzner-restic-repo1/backup-ssh.config"
  option: 
    - "sftp.args=-F /home/peter/work/hetzner-restic-repo1/backup-ssh.config" 
  backup: 
    source: 
      - /home/peter

but without success.

(The option key is even used in the azure example)

Restic's Environment Variables says:

The external programs that restic may execute include rclone (for rclone backends) and ssh (for the SFTP backend). These may respond to further environment variables and configuration files; see their respective manuals.

I could not find any environment variables that control options for ssh or sftp (openssh).

Hey!

It should work with the option flag.

I suspect it could be an issue with the space.

You can run resticprofile with --dry-run and/or --verbose mode so you can see what's actually called by resticprofile.

When I try I can see it's sending the parameter: --option=sftp.args=-F\ /home/peter/work/hetzner-restic-repo1/backup-ssh.config which should work?

DUH!

My mistake.

In the backup-ssh.config I called the host hetzner-storage-box, but in the profile definition, I referenced the host as sftp://hetzner-backup/. Once I changed one to match the other, it worked. Both for option as a scalar and for option as an array.

So there was a problem, just much simpler than I thought. Thanks, @creativeprojects for confirming that I was on the right track and that the options parameter wasn't the problem. --dry-run was the key debugging tip.
