Backup task status is: error

[LaszloI]

Hy, after June 10, I cannot create backup from plesk to an external FTP repository. File was transferred I can open the TGZ file, but Plesk send me an email: "Creation date is: 2013-Jun-16 17:34:54 Task status is: error". In Backup manager there is a local copy, I can see backup under personal FTP tab, but under current tasks tab there is a message: "Personal FTP Failed Remove". Log:
