Azcopy empty folders

Question

I need to sync data from a local server to an Azure Cloud v2 storage account. I’m using the command azcopy sync “source server” “storage container “ —-delete-destination=true but the issue I’m facing is that empty folders are not managed correctly. In particular:

• if present in the source then they are not created in the destination
• renaming a folder in the source the destination structure is recreated leaving the previous folder empty

E.g. Initial situation in source and destination is a MainFolder containing a file 1.txt

The final situation in the source is a RenamedFolder containing the 1.txt file

I expect everything replicated at the destination instead I find: The RenamedFolder containing the 1.txt file (this is ok), The NewFolder is empty (this is not ok)

Of course, from website, I can create and remove empty folders (v2 account) but I need to sync a lot of data so I cannot do it manually.

Any idea how to solve it? Isn’t this supported in v2 storage accounts?

Answer 1

I need a complete replication of the local folder in Azure storage. This means I need to see empty folders and not find empty folders if a folder is renamed locally.

• AzCopy sync does not support creating empty directories in Blob storage (Gen V2 storage account).
• AzCopy sync "source" "destination" --delete-destination=true does not delete empty directories.

Even when I tried, I encountered the same issue in my environment, and it is still not creating empty directories or folders and not deleting empty directories:

Output:

 azcopy sync "[Source]" "https://xxxx.blob.core.windows.net/test?sp=racwdlmeop&st=2024-01-22T06:48:30Z&se=2024-01-22T14:48:30Z&spr=https&sv=2022-11-02&sr=c&sig=xxxxx" --delete-destination=true
INFO: Any empty folders will not be processed, because source and/or destination don't have full folder support
