Google Drive backup with Rclone

Completed binary packages for Linux, Windows, Mac OS, the BSDs, Plan 9, and Solaris can be downloaded from Rclone's website [1]. If you would prefer to build your own and you have a Go compiler on your system, you can proceed with the command

go get -u -v github.com/ncw/rclone

rsync cross-infra

rsync via ssh tunnel is convenient to replication files between site, by 'ssh -p port' and -avz in one-line. cheaper than backup into cloud infra.

video site sync

要將video site或website進行replication，看是近端或遠端，用SDS或是一般rsync (配合iNotify比較方便，不用基於cron job)都可以。static web pages比較單純，規格一致，但video site最好定義清楚video spec，這樣成長率才能SOP好好估算。

• video bitrate and container (ex. mp4) selection.
• video codec and profile, e.x. H.264 High.
• audio codec.
