My issue is similar or even worse. I only signed up for Office 365 last week, and jumped to 1TB of space. I had a new laptop and wanted to keep the old one but mirror files across via OneDrive. I expected an initial flurry of activity, like when I set
up BT Cloud a couple of years ago, and then a drop to very little activity.
There are tens of threads in the community about this issue, over many years, yet there seems to be no explanation of what is actually happening. I didn't want to start yet another one, and my issue seems similar hence posting on this latest of threads
I could find.
Last week, OneDrive had finished processing changes. Yesterday, it was processing 65000 changes. When I went to tea about 3 hours ago, it was processing 4300 changes, so I thought it must be nearly done. On return, it is back up to a silly number again.
It was showing as Processing 117000 changes, but it wouldn't show me what it was doing and what is uploading or downloading. (All numbers rounded to nearest 1000 for ease of typing). The number was slowly reducing in all instances.
I found a thread on here that suggested pausing and restarting sync. I have done that, and on restarting after about 10 minutes, it said "all files in sync". But within a few seconds, it started uploading files again. It has been uploading photos for a
quarter of an hour, and all it has been showing is "OneDrive Processing Changes". Now it is showing "Processing 218 change", and a few seconds later "Processing 915 Changes", now back to just "Processing Changes". It is STILL uploading, and the number to
process is constantly increasing in leaps and bounds. Now up to 13,204, and in the time taken to type this, 15,242. About 3 minutes later, and it is 8,298.
When I looked at the settings, I have my system set to keep all files on my PC, and it is only uploading not downloading. BUT the web interface to my OneDrive has, since last Wednesday, remained at "Using 525GB of 1TB". The total storage used is not changing,
so it must be overwriting the files that are already uploading.
I wish it would give more information about what it is thinking. I haven't gone near those photos in months, so why are they needing to be synced?
Why? Why? Why?
