Online backup cancels immediately after starts in Cloud Backup Service Posted April 19 On 4/16/2021 at 10:19 AM, Twinbytes Inc said: Another update now. I put back to manual and did a cleanup. It's been running perfectly for over a week now. other fixes were temporary but doing a cleanup seemed permanent fix. Incase anyone else has this issue. Just do cleanup keeping the latest version of all files backed up. Hmm, that is interesting. I have not looked at the Cleanup section before. Avast has said we have unlimited storage of old versions of files, so I never bothered. Apparently, there is a limit.
