Ask HN: A document strategy for one man business

I have left my job and will be working for myself and am trying to get my files in order i.e. office documents and their backup/syncing.

I want my files to be synced locally and to the cloud. My primary os is Ubuntu.

I like to Google's stuff but as I'm a Ubuntu user Google support for Google Drive is poor. I have tried Insync for a while but have found the software unreliable regarding syncing.

I have experimented with Nextcloud but I'm not sure I want to run my own server.

I used to use dropbox but I found their sync process slow and annoying on boot.

So, any suggestion from happy users of an alternative strategy for managing office documents and their backup?
