refine the algorithm and notification processes
I ran into issues where I would reinstall windows or move my onedrive folder, I would sync with an existing copy of my onedrive folder. I do this because it's GB's large and on a slow internet connection. A number of times, music in my music folder would be duplicated because of some unfathomable change, files deep within say an Eclipse workspace would be duplicated because of unfathomable changes Mind you, files that I haven't touched in months would be duplicated because both copies have changed somehow. THEN, on top of it all, it would take AGES for it to sync, compare, etc. By the time I just let it go, I don't know what's duplicated or whats not.
On top of that even, apparently it decided that my game backups that I use symbolic links with OneDrive as the source didn't get uploaded or somehow got deleted, and I didn't even know it! I moved my folder, instead of merging it this time because of the above problem, and now I lost game saves, programming projects, and so on. I tried checking the recycle bin, but the recycle bin can't be searched and I moved my 3000+ songs from onedrive because of the duplicate problems that I'd have to use the incredibly user unfriendly interface of scrolling down, wait for the page to get more data from OneDrive, scroll down, etc for hundreds of pages...
I expected more like Dropbox and less like an FTP server.
You can switched to the Ahsay Software – It is the fastest, secure and more reasonable from other backup solutions. Ahsay Backup Software supports backing up Microsoft Exchange Server, SQL Server, VMware ESXi (both paid and free versions), Hyper-V, and other databases. Hope this helped you out a bit.
