# SFTP as storage backend
|
||
|
|
|
||
|
|
An SFTP account on another server can be used as storage for an SFTPGo account, so the remote SFTP server can be accessed in a similar way to the local file system.
|
||
|
|
|
||
|
|
Here are the supported configuration parameters:
|
||
|
|
|
||
|
|
- `Endpoint`, ssh endpoint as `host:port`
|
||
|
|
- `Username`
|
||
|
|
- `Password`
|
||
|
|
- `PrivateKey`
|
||
|
|
- `Fingerprints`
|
||
|
|
- `Prefix`
|
||
|
|
|
||
|
|
The mandatory parameters are the endpoint, the username and a password or a private key. If you define both a password and a private key the key is tried first. The provided private key should be PEM encoded, something like this:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
-----BEGIN OPENSSH PRIVATE KEY-----
|
||
|
|

|
||
|
|
-----END OPENSSH PRIVATE KEY-----
|
||
|
|
```
|
||
|
|
|
||
|
|
The password and the private key are stored as ciphertext according to your [KMS configuration](./kms.md).
|
||
|
|
|
||
|
|
SHA256 fingerprints for remote server host keys are optional but highly recommended: if you provide one or more fingerprints the server host key will be verified against them and the connection will be denied if none of the fingerprints provided match that for the server host key.
|
||
|
|
|
||
|
|
Specifying a prefix you can restrict all operations to a given path within the remote SFTP server.
