Taking a backup blocks FTDC gathering while the backup commences, I haven't yet determined if that is only when the backup starts or if it is for the full duration of the backup.
This can reproduced easily with the following patch using the incr_backup test:

Once the test completes open the WiredTigerStat* file and the FTDC appears to have gaps in it.
