Azure File Sync - filenames downloaded to the sync agent on-prem

@PeterRichardt-4556

Azure File Sync does not log every file that is synced. We only log when files fail to sync: Troubleshoot Azure File Sync

If you are looking at “Bytes synced” metric and seeing download activity, you could enable logging on the Azure file share to determine who is updating the files and which files are updated.

If your looking at the “Cloud tiering recall size” metric, look at Event ID 9059 on the server to determine which application(s) is recalling files.

Edit: Also learned that if Commvault is being used to backup Azure file share, Commvault backup service by default sets the archive bit and the access time on the files.

To prevent this, the user should change these settings:
• Select “Preserve File Access Time“
• De-select “Check archive bit during backups”

Caveat: It does increase the backup time, but it should not be too much.

I was able store the logs now to LogAnalytics and to create a query for the "upload" or better called creation.

StorageFileLogs
| where TimeGenerated > ago(1h) and Protocol == "SMB" and StatusCode <> "0" and OperationName == "Create"

What could be the the "download query" look like? I created a file on Azure via Portal Website upload and can't find the download entry.

Are u sure it is being created in Azure?
