Thanks for checking back with us, @Carol_at_GGM.

The message you're seeing means that a copy of the backup that is older than one year can not be restored. This doesn't mean that the data in your company that is over a year old won't be restored.

QuickBooks won't allow older copies so your data can stay as up to date as possible. For example, if you were to restore a back up that was made 11 months ago, your current data wouldn't be included. However, if you restored a recent back up, all your data, even over a year ago would be included. 

I hope this helps explain the backup process a little better. Please shoot me a reply if there are any other questions or concerns. Take care!
