+### Azure
+
+To do a backup on Azure, first install [Azure CLI](https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-linux?pivots=script#install-or-update-azure-cli) and [azcopy](https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-v10?tabs=dnf#obtain-a-static-download-link). You must also have setup a storage container with blob storage. Otherwise, the instructions are the same as for AWS above, other than when working with S3. Here are the commands to access Azure blob storage instead of S3 for copy/download of the backup.

+#### Do the backup
+
+```bash
+az login # --use-device-code if web browser not available
+
+cd /data
+# Tell AZCOPY to use same auth as CLI
+export AZCOPY_AUTO_LOGIN_TYPE=AZCLI
+# copy the tar backup file to blob storage
+azcopy copy 2021-04-23.tar "https://[account].blob.core.windows.net/[container]/nebari-backups/2021-04-23.tar"

+#### Do the restore

 ### Digital Ocean
 
 Instructions will be similar to those for AWS above, but use Digital Ocean spaces instead of S3. This guide explains installation of the command-line tool:
