This error is returned from an FTP server when it cannot store a file that is being sent to it (from SyncBackPro, SyncBackSE, SyncBackLite or SyncBackFree). There are three possible reasons why the FTP server may return this error:
  • The drive (on the FTP server that the file is being stored on) is full (or there is not enough free space available for the file being sent)
  • The user has a limit on the amount of disk space (on the FTP server) they can use (a quota) and they've reached that limit (or will exceed it with the file being sent)
  • The permissions on the folder (on the FTP server) do not allow this user to store files in it
You may need to contact the administrator of the FTP server to resolve this issue.
