Backup from Gaia OS to FTP server fails if user name is defined as "Domain\User".
Traffic capture during backup shows that Gaia machine sends "DomainUser" to the FTP Server instead of "Domain\User", which causes the authentication on FTP Server to fail.
Cause
Backslash "\" character in user name used for backup (e.g., Domain\User) is not saved in Gaia Database when creating a backup.
