You are correct - the progress first shows the number of files to be PROCESSED (checked for changes) then I believe once the green bar starts showing it has switched to the number of files to be UPLOADED.
At the moment there isn’t a way to shortcut that process to skip right to the necessary upload amount.
I know it’s not really what you want, but if you check the job “General” log (or emails, if using them) AFTER the run you should see something similar at the top which summaries what WAS changed:
Hmmm, in my version (18.104.22.168_beta_2018-04-02 on Windows 10) the part when the green bar starts shows the remaining amount to be checked with OR uploaded to the destination, which isn’t the same as the amount to be actually uploaded.
Thanks for this, but yeah, it’s more for me to see if something/someone has changed a bunch of files without me knowing. Real world example: once the Mrs accidentally added 20GB of unintentional data to monitored folders without realising they were being backed up. CrashPlan showed me how much was still to upload (as well as the current file being uploaded), and I could fix it before the backup finished.
I can live with the current Duplicati behaviour, but it definitely would be a nice-to-have to be able to see an accurate upload amount (and ETA) of a running backup.
In this case I know I’ve added about 3GB of new data to this backup, but there is no way for me to see how much data there is to upload with the current “to go” reporting. After the 3GB is done uploading (a while at my upload speed) it will go from 200GB down to 0 very quickly. It would be useful to have a semi-accurate ‘upload to go’/ETA :).
