Backup SSH auth
Prefer a full private key for scheduled backups. Password auth needs sshpass on the app server.
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.
