Hi @morganflame,
We do not officially support moving the whole odrive folder to an external drive. You can use “sync to odrive” to create a sync relationship between an external folder and a remote folder. This is a Premium feature and you can read more about it here: https://docs.odrive.com/docs/manage-sync#section-sync-external-folders
It sounds like you are looking for a traditional backup solution. odrive is currently a sync solution and not quite the same as traditional backup. Sync may be a bit heavy for what you want to do, although there are many folks who use it this way. I got into this in more detail in this post, if you are interested: Backup (one-way sync)
