there is never enough backup
I am a PhD student in computer science, and this is how much I am paranoid about losing my PhD dissertation.
To clarify on the implementation, I am using these instructions to synchronize between Overleaf and my computer, and between my computer and the two other Git servers. And, I am using duply on a Cron job to backup my private server’s git repository to..well, another server.
I do not use a commenting system anymore, but I would be glad to read your feedback. Feel free to contact me.
