    thanks for this excellent article.
    i have followed your steps and successfully created a backup job from my synology share to an Azure cloud blob storage.
    My main concern now is on how can we restore this backup to another synology box incase the current synology NAS crashes or dies.

      In your new Synology system you can connect your Azure Cool Storage to Hyper Backup and restore data to whichever folder you like.

      There is a Restore button on the bottom left corner to restore backup.

      • – Select the version of backup data you want to restore
      • – Specify the folder where you want to place your backup data
      • – Start restore process and just wait for it to complete

    Great, clear and simple to understand article.

    I would like to know that you informed “In general, any data which lives for a longer period of time and is accessed less than once a month is the perfect candidate for cool storage.” but would like to know if from Synology Hyper Backup I schedule backup on daily basis and not less than once a month, then also I can select Azure Cool Blob Storage or should I select any other options.

    And what can be the approx prices for Azure Cool Blob Storage for storing 1 TB of Data.

      For more details on Azure pricing you can have a look here. Approximately, 1TB of data will cost you around 10$/month.

      Now related to the first part of your question. Have in mind that the Azure cool storage tier is optimized for storing data that is infrequently accessed and long-lived. The difference between Hot and Cool storage is in availability (99.99% for Hot tier, 99% for Cool) and that in Cool Storage you have lower storage costs but higher access and transaction costs.

      Storing data in Cool Storage tier is very cheap so daily backup is fine as long you don’t request the backed up data very often. You don’t pay anything for data going into Azure data centers. For example, I perform daily backups for my photos but I rarely access them from Azure. I have it as a backup plan in case my NAS some day fails.

    I would recommend adding in a comment that you need to disable (or not enable in the first place) “Secure Transfer Required” otherwise Hyper Backup will fail to create the backup task.

    Thanks very much for your guidance on Azure backup with HyperBackup. Does this backup procedure do incremental backups after the initial backup is taken?
