[GNC] Backup recovery

[Finbar Mahon]

Hi,

I know this has been asked before and I have read some of the the 
threads, however...

I am trying out Backblaze, the continuous backup to the cloud service.

I wanted to check if my files were recoverable and I found -

....and more, all dated the day before yesterday, when I did the backup 
trial.

1. Do I need to restore all of these, if not which ones?

2. I found them in my file explorer, is there any other place, by 
default, where the files are?

3. Can somebody point me to a link or links which explain the 'best' way 
of storing GNU files?

Using Windows 10 PC with Version: 3.4 Build ID: 3.4+ (2018-12-30)

Thanks, Finbar
