Hi there and welcome
Are you referring to a previous icloud backup or one via iTunes?
Please let me know
The only way is a total restore from the backup, if the older one still exists
To check this, Go to Settings > iCloud > Storage & Backup
Look for a backup date when you had the message, and restore the backup to the phone which will bring your phone back to that date.
If the date does not exist it will not be possible sorry.
Let me know how you go please.
ok sorry, then it would not be possible.
If you would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
