Let me set the stage here.
I have a paid Google Drive subscriptions of 2 terabytes.
I have an iMac where I have a complete synced copy of my Google Drive onto a 3 terabyte USB drive. This includes a large photography folder of approximately 983 gigabytes.
I have a openSUSE Linux system where I have synced a single folder from the photography folder. This sub-folder contains approximately 5 gigs of data.
I accidentally removed the sub-folder. No problem, I should be able to restore from trash and continue. Unfortunately, I discovered that not only had the sub-folder been moved to trash, but the entire photography folder. In others words by deleting a folder that contained approximately 5 gigabytes, Insync deleted the entire photography folder containing approximately 983 gigs.
I verified that the entire photography folder was now missing on the iMac system.
This is a serious issue. I have 1 Terabyte per month Internet connection. To fully restore the sync
on the iMac is going to take 2-3 months considering that I can only use 3-4 gigs each month (I also use other streaming services).
This is very ugly and unacceptable. It also represents a potential Denial-Of-Service.
