Considering using azcopy copy or azcopy sync in a crontab. This would allow you the upload the new or changed files directly to blob storage at your desired time. The below entry would copy the directory and its contents to blob storage every day at 1:00AM.
0 1 * * azcopy copy '<local-directory-path>' 'https://<storage-account-name>.<blob or dfs>.core.windows.net/<container-name>/myBlobDirectory' --recursive
Hope this helps! Let me know if you have any issues or further questions.
