My company is late to the work from home party. As of 1/1/22, I have a hybrid situation and can work from home sometimes, but don't always know ahead of time when that will be. Because of this, I use OneDrive to store my QuickBooks file. I am a single user on Premiere Nonprofit 2020 Desktop. I have two computers,  home and at work, with the same version on both. 

At the end of each day, I run the QB automatic Create Local Backup process and that file saves directly to the OneDrive. The next day, I move the file to where I am working (home or work) and run the Restore Company file. This means I am almost always running on the restored backup file. Let me be clear, I do not run QB with the file while it is on the OneDrive, just the one housed locally.

My question is two parts:
A) Is this the best process to ensure I am using the most current file? Should I be backing up locally and then moving the backup to the OneDrive? Or should I be moving my daily full file (.QBW) and the associated .ND & .TLG files to and from the OneDrive.

B) I use attachments, which is a huge file. Do I need to move the entire file every day or is there a way to move just items I "attached today" to the OneDrive? And then move the Attach file to where I am working locally the next day.

I hope this is clear. I have looked at a lot of posts regarding OneDrive and I understand it can only be used to store the file, not run QB. My employer will not spend money to host separately, etc.
