FTP storage setting for backups for multiple subscriptions.
When added the FTP server storage parameter in the settings of the Plesk panel (tools&settings - Backup Manager - FTP Storage Settings) for the backup.
Automatically distribute this FTP repository to all subscriptions as a place for backup by default.

Now it is possible to change domain's backup Settings one by one only.
Add possibility specify backup settings for several domains.
