Cloud backup upload all the files every time in new versions?

TrueNAS General

Hello,

      after updating to the most recent Truenas versions (up to 25.10.7 - Goldeye) it seems that data protection -> cloud backup with PUSH/COPY option upload the entire content of the nas at each run, overwriting the cloud content for the files with the same name.
Older versions was working differently: only changed or new files were copied at each run! This is a big problem for me as it runs forever due to the several TB of data.

Has anyone noticed the same behaviour? Of course if I want a full match between cloud and the nas I can also run a SYNC task, but for PUSH/COPY I'd not expect everything is copied again at avery run.

        Thanks for your help, Mauro

PUSH/COPY redoing every file means the compare is failing, not that the task suddenly wants a full copy.

open the job log and look for Skipped vs actual transfer bytes. if bytes climb on every unchanged file, remote metadata (mtime/hash) stopped lining up after the update.

common after a TrueNAS bump: remote encryption on, or the bundled tool changed how it stores compare info. say which provider (b2, s3, onedrive, etc) and whether encryption is on. paste a few log lines for one file that already existed but got copied again.
