Problems when using azcopy to upload files from VM to Azure File Share

[ShengquanYu]

Which version of the AzCopy was used?

v10.20.1

Which platform are you using? (ex: Windows, Mac, Linux)

Windows Server 2012R2

What command did you run?

azcopy rm "fileshare+sas_token" --recursive

azcopy sync "localpath" "fileshare+sas_token" --delete-destination=true --recursive=true

azcopy copy "localpath" "fileshare+sas_token" --recursive=true

What problem was encountered?

Because of authorization limit, I cannot use sync agent to sync files between Azure VM and Azure File Share.
I want to back up my VM's files to Azure File Share daily, but using 'azcopy copy' alone doesn't delete files that no longer exist on Azure File Share. So I tried 'azcopy rm' and 'azcopy sync' commands.

1. 'azcopy rm' generates error logs with 'StatusCode=409;StatusText=DirectoryNotEmpty' in StorageFileLogs.
2. run 'azcopy copy' after 'azcopy rm' generates logs for 'ParentNotFound', 'ResourceAlreadyExists' and 'ResourceNotFound'.
3. 'azcopy sync' generates error logs for 'DirectoryNotEmpty' and 'ServerBusy' even with 'AZCOPY_CONCURRENCY_VALUE' set to 1.
4. run 'azcopy copy' after 'azcopy sync' generates logs for 'ParentNotFound', 'ResourceAlreadyExists' and 'ResourceNotFound'.

How can we reproduce the problem in the simplest way?

use those commands above.

Have you found a mitigation/solution?

No. I noticed that there are no problems occurring with these commands. However, Azure continues to generate these error logs, making it challenging for me to monitor the Storage Account. Since I don't have authorization to use the sync agent, are there any solutions to resolve these issues?
