# azcopy cp FROM TO --recursive

azcopy cp "https://SOURCE_STORAGE.blob.core.windows.net/container?SAS_TOKEN" https://DEST_STORAGE.blob.core.windows.net/container --recursive

Notes:

• can get the SAS link from Azure Storage Explorer…
• at the moment, it doesn’t support sync between blob accounts
• have to give yourself “Storage Blob Data Contributor” access
