Migrating backups from file systems to Azure Blob Storage and from Azure Blob Storage to file systems
Learn how to use the nz_azConnector utility to upload and download database backups between file system and Azure Blob Storage.
Use the nz_azConnector utility to upload backups from the file system to Azure Blob Storage, and to download backups from Azure Blob Storage to the file system. With the nzrestore command and the Azure storage connector, you can restore these migrated backups from Azure.
After you run the nzbackup command to back up a database to a file system, you can use the nz_azConnector utility to upload database backup present on the file system to Azure Blob Storage and vice versa.
