Domino DAOS backup takes long time and NVNOTEAGENT.EXE process averaging 50% CPU usage

Domino plugin version '4.4.4'

Domino server operating system windows 2008R2

DAOS incremental backup appears to take near to 2.4 hours to run for 18.69MB of data. For the majority of this time nothing seems to be happening, other than on the Domino server I can see the NVNOTEAGENT.EXE bouncing in the 50% CPU usage region.
The "normal" incremental backup of the logs manage to backup around 1Gb of data in less than a minute

We also see a similar problem with full DAOS backups.

BUG 28305

This problem will be resolved when BUG 28305 is fixed.

The workaround is to schedule the backup to run early in the evening so that the backup completes before higher volumes of users require the Domino services. This will reduce any impact that this problem may cause day to day usage of the Domino services
