ReadyNAS 104 running 6.6.1 amazon deleting files

I just read a post here which claims this problem was discovered and then solved in 6.6.1. 

 

It is not.

 

I have been syncing to amazon for a few months, with a fear that this would happen, and today, 2 days after setting up a new folder structure to sync to amazon, I came home to find deletions stated in the sync log. I then verified that the files are in fact gone from my local drive.

 

This is completely unacceptable, and is a direct result of someone thinking it was a good idea to not allow the sync directions to be selectable. I use amazon strictly as a backup solution, so I DO NOT need anything that occurs in amazon to impact my local drive.

 

I have over a TB sync'd to amazon and I have NO way of knowing which files are gone now gone since the logging function can't store much history.

 

I need someone in Netgear to look into this and get back to me. I have exported the log to a file that I can share if needed.

    Of course it's always bad when data is lost.  I hope you can manage to get the files back.

     

    I am not seeing any cloud fixes in the 6.6.1 release notes.  I suspect the fix made in your linked post ended up in 6.7.0.  

     

    While you are waiting for Netgear to respond, I suggest rebooting your NAS in read-only mode.  That will prevent the deleted files from being overwritten (and not recoverable).

  • I have been trying to watch the type of files that are being deleted. I have been doing a lot fo video creation lately, and I am rendering various assets as I go. The render jobs take some time to complete and the resulting files grow as they render. It appears that these files are being uploaded to amazon at various stages of the render as it grows. It also appears that as amazon gets a new larger version it deletes the previous version. My guess is that somwhere along the way it loses track of the changes and deletes the last known version that landed in amazon, which then causes the last version on the local machine to disappear.

     

    This is only a hypothesis and still needs a remedy.

      Any writes done to the volume whether automatically (e.g. snapshot creation/deletion, scheduled volume maintenance, the system cleaning up after deletion etc.) or by you manually reduce the chances of recovering deleted data. So as mentioned it is important to get the volume mounted read only ASAP if you want to attempt to recover data.

        Amazon stores deleted versions for 30 days. I have just been recovering the files I need from their interface. The point is that this should not be happening in the first place. the readynas should not be moving files that are active.

  • The strange thing is, while the files were deleted from the NAS, not all of them were deleted from ACD!

     

    Shouldn't it be that the files gets deleted from ACD first then removed from the NAS?? Or the other way around??

     

    I had to restore my share from snapshot as I wasn't too sure what got deleted exactly.

     

    I have disable sync for now as I don't want to deal with another restore again.

     

    Can someone confirm that Netgear has fixed this issue.
