1. Set up a server that would act as the FTP storage. It must be possible to connect to that server from the Plesk server via FTP.
2. Go to Tools & Settings > Backup Manager > Remote Storage Settings > FTP.
3. Select the “Use FTP Storage” checkbox.
4. Specify the settings for the server you set up during step 1, including the server’s hostname or IP address, the path to the directory for storing backups, and the FTP username and password.
5. If the Plesk firewall is configured to ban incoming connections from FTP servers, select the “Use passive mode” checkbox. Make sure that the server you set up during step 1 supports the passive FTP mode.
6. (Recommended) Select the “Use FTPS” checkbox to use an encrypted connection when transferring backups to the remote storage. This ensures that your data cannot be intercepted by a third party. Make sure that the server you set up during step 1 supports FTPS connections.
7. Click OK.
Securing Backups in Remote Storage With a Password
You can secure backups stored in remote storage with a password.
Doing so encrypts the passwords stored in the backup, such as mail account passwords or database user passwords. Even if a third party obtains a backup, they will not be able to get the passwords stored inside.
When you restore a password-secured backup, you need to provide the password. If you cannot, all passwords stored in the backup are generated randomly.
To secure remote storage backups with a password:
1. Configure at least one remote storage.
2. Go to Tools & Settings > Backup Manager > Remote Storage Settings. The section “Backup security settings” has become available.
3. Under “Password Protection”, click the “change” link next to “Disabled”.
4. Select the “Use password protection (recommended)” checkbox.
5. Type in the password in the corresponding fields.
6. Click OK.
