I used Dropbox to backup my external drive with 520GB of content. The backup is complete and Dropbox says it's in sync, but the size of my back up is only 428GB. Such a discrepancy scares me. Is there some really good compression, deduplication, etc. being applied?
Thanks!
Hey @socksinacan, thanks for bringing this to our attention.
Have you checked the sync status of the Dropbox app?
You can see that by hovering your mouse over the Dropbox icon in your system tray/menu bar.
Do you see any error messages?
Also, what is your computer's OS and version?
Thanks in advance!

Hi @socksinacan, you can view the external drive backup on the site directly. Regarding comparing the two, currently there isn't a Dropbox feature to do so, since if it states it's backed up, it means that the files are already synced successfully.

Hey @socksinacan, and sorry to jump in.
Is it possible to upload some screenshots of the backup size you see both on Dropbox and your external hard drive, perhaps?
Also, I’d like you to check the main folders located on your external hard drive and double check their size on Dropbox, so that we can see if there’s a specific folder that’s missing data.
Let me know what you find!

Thank you for the response. I was able to get the screenshots. The Dropbox web app isn't showing folder sizes, though.
In the screenshot, it shows that the external drive backup is paused, so it possible isn't fully synced.
You can view the size of folders on your external drive on the site by following these steps.
Once you have the sizes enabled, and the drive shows as 'done' on the main Backups page, let us know if the folder sizes match with those on your external drive.

Yeah, it's been doing that when I turn the backup sync back on. Shows paused even though I've turned it back on and the app has displayed syncing and then synced. It eventually displays correctly. I'll check out these size steps when I can get back in front of it. Thanks.
Thank you for the size tip. I looked at the folder sizes in both locations, and two of the folders combined to a five GB discrepency. The rest were almost spot on between the two locations, with negligible differences. Certainly nothing to account for 80-90GB difference.
