On my initial copy I remember it staying at 99% for a long time, but it eventually finished. I was copying a lot of data so the full copy took 3.5 days. In the sync phase, I remember it staying at 99% for almost half the time of every sync and sometimes more. My first sync took 12 hours, and the second 6 hours. On the last sync it stayed on 99% too long so I stopped it and jumped to the last stage (read-only mode) and that made it much faster.
