Dropbox sync issue

Question

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 is working, and it pushed all files to Dropbox.After couple days I've noticed (in logs) that it did not start live sync, but keeps uploading files from beginning, overwriting (probably) same files that already are on this Dropbox account.ReadyNAS shows no errors in its system logs or in Dropbox session History logs.I've made some test with smaller folders with lesser files and everything was working just fine.One thing I've noticed is: my disk schedule is set to do defragmentation ones a week, and during the sync test with smaller folders and files that have to be synced to Dropbox, after defragmentation, all files was pushed to Dropbox again from the beginning and overriding existing ones - wchich does not make any sense.This is very anoying that ReadyNAS is cheching file changes on cloud account (or at least it says it is doing that) before starting to sync, but after all it is syncing all files overriding exactly same files that are already on Dropbox. I have to wait quite long to get my files to be updated on coud storage, and I'm having affected internet connection all the time (despite the lowering the QoS for ReadyNAS on my router).My question is: Do anyone had issues like that before? Should I never do the defragmentation if I want to sync my files with Dropbox account? What about disk balance, and scrubbing - it is making same issues? What is the solution?I'll appreciate if anyone could help.Model: ReadyNAS 102Firmware: 6.10.6

defrag is different from the other maintenance tasks, and if you think it is linked to the drop box problem I suggest that you take it out of the weekly schedule for a while.&nbsp; Note there is also an autodefrag option for each share that you might also want to turn off for the share you are syncing.

Let's first see if the problem resolves.

Note I don't use dropbox sync, so I don't have direct experience here.&nbsp; But there might not be a solution.
&nbsp;
Is there a particular reason to think you that the share contents have a lot of fragmentation?

Hi&nbsp;StephenB&nbsp;!Thanks&nbsp;for&nbsp;your&nbsp;answer!Yes,&nbsp;I'm&nbsp;currently&nbsp;thinking&nbsp;that&nbsp;defrag&nbsp;is&nbsp;causing&nbsp;that&nbsp;problem.Now&nbsp;I&nbsp;kicked&nbsp;it&nbsp;out&nbsp;of&nbsp;the&nbsp;schedule,&nbsp;but&nbsp;what&nbsp;about&nbsp;the&nbsp;performance?&nbsp;Should&nbsp;I&nbsp;never&nbsp;use&nbsp;it&nbsp;again&nbsp;if&nbsp;I&nbsp;want&nbsp;to&nbsp;sync&nbsp;my&nbsp;data?Thanks&nbsp;for&nbsp;the&nbsp;autodefrag&nbsp;info,&nbsp;I&nbsp;checked,&nbsp;and&nbsp;it&nbsp;is&nbsp;off&nbsp;too,&nbsp;but&nbsp;did&nbsp;not&nbsp;realize&nbsp;that&nbsp;there&nbsp;is&nbsp;such&nbsp;an&nbsp;option.

StephenB&nbsp;As I wrote before, I made some tests with syncing different, smaller folder (to be precise 225 files in 53 folders, but only ~70 MB) which allowed to test syncing much quicker. Sync time was of course less than one week, so disk schedule did not start to defrag, ReadyNAS finished uploading files, and start to perform live sync (as logs writes). I did another test, same folder as previous one. I made sure, that all filed are on Dropbox, and ReadyNAS is live sincing, I forced degfrag job, and when this job was done, I’ve noticed that ReadyNAS started to push this whole folder to cloud storage again.Now I’m syncing the whole share (not just one folder) with no scheduled defrag, and I’m sure it will finish uploading files, and start to do live sync – but it will unfortunately take a time.I’m sure that defrag should not affect the sync job.I wish to find a solution, that allows me to sync and to defrag my data.
