I have OneDrive and Amazon Cloud Drive (also a small Google Drive). I had previously done a manual upload of much of my data on two machines. With odrive I synced a lot of newer document and media files to these already created cloud folders. Odrive easily meshed in to this existing structure.
But more importantly, for my trial period I deliberately stressed the overall system by having odrive sync my W10 Local/AppData/Microsoft folder. That Office 365 folder is dynamically very busy with my subscription stuff. Plus six active Outlook mail accounts. This caused a ton of useless spurious traffic for a few days with all the constantly updating files and background system deletions in numerous folders. Pretty messy. The instructions suggest that this may not work well and cause “unpredictable” errors. However, it worked perfectly. The Amazon Drive copy was continuously maintained perfectly with no error messages nor snags in all the junk file uploads. Trash continuously had 200+ deleted files in it. There were no “busy file” complaints. This local machine did not feel bogged down, and my Internet seemed perfectly normal. Never noticed all the useless background busywork. No choppy YouTube videos, etc. It added many gigabytes to my Comcast tab. I can’t believe how seamlessly it worked.
So after a few days I did Remove Sync and deleted that junky folder from my cloud drive. Then I subscribed to Premium. This is a great product which I imagine will only get better. I decided I did want to keep copies of just my Outlook files, and I am doing that. As I mentioned in the Feature forum, I’d like to be able to set a sync schedule for some folders such as for Outlook to reduce spurious constant updating. Nevertheless, no matter what crazy stuff I do, there have been no errors at any time.
Next thing to try are my Linux machines.
