Cloud Sync does not sync
Files would be pulled from Google Drive after initialization and folder creation from Cloud Sync. When I tried to rename the file on File Station, it worked. I then try to rename the same file on Google Drive, but it doesn't work. I tried renaming the file on File Station once more, but the change did not sync with Google Drive. Even though it was only a few moments ago!

Cloud Sync won't sync, but says "up to date"
I used Cloud Sync to "backup" my Dropbox and OneDrive accounts on my DS110J, but I had to reinstall it due to a configuration error. It now simply says "Up to date" when I add an account to Cloudsync; nothing from the Dropbox or OneDrive account is synced. I've tried changing the DNS and reinstalling CloudSync, but to no avail. I installed cloud sync from Package Center and have the most recent DSM for DS110j.
Why is Synology Cloud Sync Not Syncing All Files?
Several factors could contribute to Cloud Sync not syncing all files on Synology. Let's see how they differ from each other:
- Insufficient Cloud Storage Quota: If your cloud storage account has insufficient space, the sync process might fail to complete successfully. So, you have to get more cloud space to ensure you have enough storage available in your cloud account to accommodate all the files you want to sync.
- Network Connectivity Issues: Stable internet connectivity is vital for the smooth functioning of Cloud Sync. If your network connection is weak or unstable, it can interrupt the sync process and lead to incomplete synchronization.
- File Size Limitations: Certain cloud storage providers impose file size limitations. If you're trying to sync files that exceed these limitations, the sync process may halt or omit those large files.
- File Name or Format Conflicts: Sometimes, certain characters or file formats in the filenames can lead to conflicts during the sync process. These conflicts can prevent specific files from syncing.
- Synology Cloud Sync Configuration Errors: Incorrect configuration settings in Synology Cloud Sync can also cause sync issues. It's essential to review your settings to ensure they align with your cloud storage preferences.
Troubleshooting Synology Cloud Sync Not Syncing All Files
Now that we've identified the potential causes, let's explore troubleshooting steps to resolve the sync issue:
Way 1: Check Cloud Storage Quota
Verify the available storage space in your cloud storage account. If it's nearing capacity, consider freeing up space or upgrading to a larger storage plan.
Way 2: Ensure Stable Network Connection
To avoid network-related sync issues, ensure that your Synology NAS has a stable and reliable internet connection. If necessary, consider using a wired connection for better stability to get rid of the Synology Cloud Sync suspend trouble.
Way 3: Verify File Size Compatibility
Check if the files you're trying to sync comply with the file size limitations set by your cloud storage provider. If some files are too large, consider compressing or dividing them into smaller parts.
Way 4: Resolve File Name Conflicts
Review your file names for any conflicting characters or formats. Rename files if necessary to avoid potential conflicts during the sync process.
Way 5: Review Synology Cloud Sync Settings
Double-check your Synology Cloud Sync settings to ensure they align with your cloud storage preferences. Adjust any settings as needed to facilitate a smooth sync process.
