Is this a passive download or is the server end collaborating with its own rsync instance? If it's the former, rsync may not be gaining you anything as it has to download everything anyway for comparison purposes, unless you just trust the mod times of the server end files. Even if you do trust them, any modified files will have to be downloaded in their entirety. If OTOH there *is* a collaborating rsync server at the other end, that makes all the difference. You might also want to consider rclone, which can work with rsync and a lot of other cloud storage options. poc -- _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
