Hi, I am in quite a pickle. I was using Synology Drive Cloud Sync, to synchronize files with OneDrive. If I am correct, this process has caused mass file corruption and deletion. Let me explain what I mean by file corruption:

Suddenly most PDF’s can’t open. I get an error that the file is corrupted or what have you. Similarly, I am finding word and excel files that can’t be opened.

Specific to PDF’s, when I opened a couple of them with text editor, they say “CLOUD SYNC” at the top followed by some mumbo jumbo referring to an encryption key. So I don’t feel I’m out of line suggesting that Cloud Sync is the culprit. I was really surprised to find it was apparently intentionally altering the files. But while a major number of these occurred in the last several days, it appears there are other corrupt files going back weeks.

And as I said, it appears To have been deleting a lot of files also.

And other problems include files/folders with long strings of numbers and letters and ending in $sshnew$ and $sshold$ There are files and folders that are duplicated and end in _1 but neither the original or duplicate can be opened.

Anyway, waiting for Synology support has been a nightmare. They keep requesting a remote code, then missing the time before the code expires. Meanwhile this major corruption of files is causing a great deal of pain.

Is there a way to revert everything back in time, or another way to get all these files reverted to their previous form? One at a time will be a nightmare, because it’s thousands of messed up files.

Hi and welcome to the forum.

Sorry about your current state, but do you have a backup of these data? It might be a fast and solid way to restore them that way.

This may be caused by resync when you messed up with the encryption, i remember a similar issue and all files were restored as encrypted files in stead of normal.
did you change the encryption setting or restarted a new sync while one side was encrypted?

Thank you, Rusty, for your reply. I especially appreciate the photo of the HDD brackets with 2.5” drives...
