Backup SSH auth
How the app authenticates to the backup SSH host.
Where to find it
Admin → Backup
| Field | Key | Notes |
|---|---|---|
| SSH private key | backup_ssh_private_key |
Full PEM/OpenSSH key including BEGIN/END lines |
| SSH password | backup_ssh_password |
Optional; used only if sshpass is installed |
Prefer a key. Password + sshpass is allowed but fragile. An env identity file (BACKUP_SSH_IDENTITY_FILE) can override a pasted key.
Leave secret fields blank on later saves to keep the stored value.
Common problems
Scheduled backups fail auth, password "works" interactively
Install key auth into authorized_keys. Ensure sshpass exists if you rely on password only.
Key rejected
Wrong key pair, passphrase-protected key pasted as-is, or remote authorized_keys missing the matching public key.
