Question on differential / full backups

We have an existing policy on our file server to do bi-weekly full backups, then incremental backups monday-thursday. We stopped all backups last week due to an issue on the Windows server and now we want to start it back. Today's regular schedule would be to do a differential incremental backup. Because there was no last full backup, will it try to run a full backup today instead?

It will only run as a full if

It will only run as a full if the prior full that the prior incrementals were relying on has expired.

If your previous full backup from two weeks ago still exists, then the next incremental will still be an incremental - i.e. it should not matter that you missed one full backup - as long as the previous full has not since expired.
