If I may revive this one, I’d like to add that full support of this feature isn’t necessary for it to be useful. One thing I discovered is that while I’m working on some file in my synced directory (in my case, it’s a LaTex source file for a paper I’m working on, but that shouldn’t restrict the use-case), I tend to make many little amendments in the course of a few hours.
It would be terrific if I could right-click the file and ask Insync to let Google Drive know I want the current version of the file to be kept forever (or, at least, until I’m sure I like the changes I’ve made), because I tend to blow through the 100-versions-Drive-limit and lose valuable previous versions. Any restoration I need to make would be much much rarer, so I can certainly make-do with logging into Drive to do that manually.
Even better, if it would happen automatically for files I haven’t changed in, say, 12-24 hours, and now make 30 new versions in the course of a few hours. Whenever that happens, I’d love for Insync to automatically tag the version I had when the morning started as keep-forever. Let me know if I ever reach the 200-kept-versions limit, or just cycle old versions when we get there; I’m pretty sure that after 200 days working on it, most files will already reach their completed version.
I think your scenario requires a change of workflow.
To avoid too many writes I turn off insync when I’m doing work,
then turn it back on at the end of my work session.
Alternatively a simple extra feature could be specifying the time between synchronizing changes.
i.e. realtime,5,10,15,30,60,120 minutes between sync option
You’re right, that change would handle my scenario. However, it’s a difference of degree, not kind, from the simple solution of not using sync at all, but rather uploading everything I want kept to the cloud manually.
The whole point of Insync, for me, is that I don’t need to think about it. My files are my files whether I’m at work, at home, or on my phone, and I can even get to them from Drive if I log from somebody else’s machine.
