The backup creation was modified because the size of the uploaded data had been increased to 2 GB.
Now when you create a backup copy, the server asks you to wait for a while, until it prepares the package. During the processing time, the server says Preparing for downloading, and when the package is ready it shows the link ready to Download.
On the download page, you can download or delete the created backup files.
The backup file will be stored for 5 days in your account. To create a new backup in this period, you need first to delete the old file.
