Does the tool sync photo modifications? #13

Closed benblo closed 4 years ago

benblo commented 4 years ago

Hi! Not sure what to expect from the tool, once I've made the initial backup, if I then modify photos (from the web interface or mobile app etc), will it sync them on subsequent runs? Or does it only download originals? Basically I'm wondering if the tool has access to the elusive "last modified time". I was initially tempted to use rclone as a backup solution, but was put off by the limitations.

Could cpd potentially be used as a 2-ways sync tool? My internet access is not super fast, and viewing pictures in a browser isn't ideal... I still miss Picasa, and having pictures right there in the local filesystem :'( !

Yes, I think it would. But you may have to use the -start file to force to rerun from a point anterior to your photo's creation date. And/Or to remove the progress tracking marker at $HOME/Downloads/gphotos-cd/.lastdone

If by 2-ways, you mean to use it to upload files to Google Photos as well? In theory I think it would be possible, but it does not do that at all at the moment.

Thanks! Yes my question was more about the theoretical capabilities; if this cdp-wrapper can act as a workaround to a proper/complete API, then I'd be happy to write my own tool to do what I need. I guess I'll just have to find some time to poke at it and see what falls.

If I understand correctly, one thing that's missing anyway is a way to ask for a list of all new events/modifications since , right?

How stable do you imagine this DevTools Protocol thing to be? I saw the "what if" header in the readme, I'm just asking for a gut feeling as this is far from my area of expertise, is it more "so brittle it'll change every month" or "good chance it'll last for years"?

If you're asking about the viability of https://github.com/chromedp/chromedp , given that @mvdan is maintaining it at the moment, I'm pretty confident about it.

As the question seems to be answered, I'll just go ahead and close this issue.
