Estimated time for completion of a job

I am running duplicacy as a stand-alone app on a Synology DS1819+. I have two jobs running, started about the same time, both with -threads 8 option:

  1. 154.88 GB/343,242 files/122,414 folders - upload speed about 2.4 MB/s
  2. 418.21 GB/ 25,574 files/ 3,439 folders - upload speed about 3.8 MB/s

The estimated completion time for 1) is 23 hours
The estimated completion time for 2) is 70 days!!

Is there anything wrong?

Many thanks for any help

I failed to exclude the Synology snapshots (which don’t show up in properties) and so the the real file number and size was much bigger.
