Dropbox sync issue
Hi Guys! I'm having issues when syncing to Dropbox. Currently I'm syncing one Share (about 117.7GB) to my Dropbox account. I started the service with no problems, ReadyNAS writes in logs that sync ...

I wish to find a solution, that allows me to sync and to defrag my data.
Note I don't use dropbox sync, so I don't have direct experience here. But there might not be a solution.
Is there a particular reason to think you that the share contents have a lot of fragmentation?
To be honest I have no idea. Until the problem occurs I was doing defrag every week, so I think it is compacted now. I’m using HDDs so, surely degree of fragmentation will rise in time, and it will affect the performance.
By now in my opinion it is software issue, because when I set the disk schedule to do defrag every week - data should be mostly compacted. During defrag ReadyNAS had to move just several files, because it was doing this job quite often. As a result most of the files are intact – so why after defrag job, ReadyNAS detects file changes in entire Share and stuck in sync loop?

Just to be clear - defragging a fragmented file will compact the file. But in the case of btrfs, defragging can reduce free space (esp. if you use snapshots). And BTRFS defrag won't compact free space. So it is a trade-off.

It's the dropbox cloud service that is deciding to resync the share, not the btrfs file system. At this point we don't know why. Personally I don't use the service, so it's not something I can diagnose. You could log in with ssh, and see if you can compare the file and folder attributes before/after a defrag. That might give you some clues.
You could contact paid Netgear support, and see if they can fix it.
