Saving the versions of the backup copy

I have task in Acronis True Image Echo Enterprise Server 9 for the folder backup, the type of the backup is full. When this task executed the old backup copy is deleted and new one is created, and name of the backup file is not changed.
How to make, that Acronis did not rewrite backup copy, and kept the previous versions. And that in a file name remained number of the version of a backup copy? And it is will be better that in a file name automatically date of the backup copy creation was added?
Is it possible?
