If first run of a new backup job stops at 90%

I have a new backup job that is around 4TB to offsite.

The first time I run this job I stop it after a few days when about 80% done. When I restart the job, even though 2-3TB has been uploaded the job starts uploading from scratch as nothing was uploaded at all. If I stop this second run at 95% and later restart this will also start uploading as if the target was completely empty.

I’m just wondering if this is the correct intended behaviour?

PS:
Thanks to all involved for this very nice software!

Does After interrupted backup, Duplicati wants to start re-uploading everything! and its links fit your situation?

Thanks for the reply!

Yeah that might be right. I was probably a bit optimsitic saying it reached 80% after a few days on the initial run, it took more days than that. So when restarting the job and it running maxed out reaching 70-80% after a couple of days it might be it 's “just” doing the re-echecks kenken describes.

Thanks!
