Ghost 15 hangs "reconciling volume" at 1% on incremantal backups

After running successfully for several months, my new installation of Ghost 15 has started to give problems. I have a backup scheduled to run on the first day of each month, starting a new set, followed by increments each day. This has worked without difficulty until now.

 

What goes wrong now is that the incremental backups stick at 1% with the window showing “reconciling volume”.

 

I have to cancel this and then to ensure that I have viable backups I manually run a full backup every day, but I shouldn’t have to do this.

 

What has gone wrong ?

 

Note : I’ve seen on other sites and other discussions that this could be caused by running a disk defrag between the full backup to start the set, and the subsequent incremental backups. This is not the case.

 

Just to remove any doubt about defrags, I did defrag the disk and then I immediately did a full backup. The first incremental backup the following day failed.
