I'm not sure what prompts a new backup being created.
I currently have two backups. One dated 2/1, and another created since 2/1 that has been updated since. A new backup may be created after installing a firmware update.
The backup is based on the name of your iPhone.
You can change the name of your iPhone to something different, and manually create a new backup for the name change.
Afterwards, change the name of your iPhone back to what is was for the current backup for this name to continue being updated.
For some reason iTunes seems to overwrite the existing backup with a new one, unless (as has been noted) there is a firmware upgrade. It is possible to keep some old ones and force a new backup file....
Go to the backup location (mac is similar):
C:\Documents and Settings\<name>\Application Data\Apple Computer\MobileSync\Backup
And notice the folder names - Noticing the naming convention.... The folder without a numeric ending is current. It is possible to give it a time/date ending and then it will not get overwritten. So if you have a bunch of folders, take the one without a numeric ending, copy it and just add "-20090321-091358" to the end of the copy. To the system it is no longer the current backup, but it was made on date-time.
I have done this successfully quite a few times - I usually do it before a firmware upgrade, just to make sure.
Before you backup again, look at the backup list in iTunes and you should see an "old" backup with whatever date and time you gave it. Your next backup should be the same alpha-numeric string and no date-time.
