Cause

The cause is the lack of available disk space on FTP-server.

If in backup settings the maximum number of backups in repository is specified, the scheme of backup creation in personal FTP repository looks like:

1. Creation of the backup on the server
2. Uploading the backup to FTP repository
3. Removing the oldest backup on the FTP repository (if the maximum number of backups is reached).

Resolution

Free enough disk space on the FTP server so that it is possible to upload a backup.
