I have been using Linux
gsync, as described below, by creating the jobs in OSX (local dir to S3) and then exporting the tix file out. That more-or-less seemed to work.
gsync on Linux log is showing a message that it can't mark timestamps on the S3 side. As a result, every backup that runs is overwriting every file again with the message "An older version is overwriting a newer version"
Ie there a linux switch command to tell
gsync to ignore the timestamp and only use file sizes. Or simply ignore overwriting the file if the file exists. Or another solution :D
gsync job-update /?=ignore-time
