Storage replication (one source, three or more targets) for live file servers RRS feed

  • Question

  • What is the best practice for storage replication (one source, three or more targets) for live file servers in Azure?

    Blob replication will only handle 2 as far as I know and is intended for DR as opposed to replicating files across data centers.

  • Hi,

    You are correct the replication native to blobs is more for DR, and is only available as a read only copy in the second Geo zone.

    If you are using IaaS VMs as file servers have you considered the option of using traditional DFS Replication built in to Windows server?

    Alternatively you could try and get creative with the Azure CDN service?

  • Hi Pras,

    For replication across different region in addition to the 3 + 3 copies for Geo-redundant storage, there are some methods which you can do.

    You can't really attach a disk in another region to your primary region.

    1. Use azure backup to backup the folder to Backup Vault
    2. Use DFS to replicate to another VM which is domain join, and hosted in another primary zone
    3. Attach Azure Files network share to the VM, and run a sync agent (such as Microsoft sync toy) to do a replication to the mapped network drive.
    4. Use online services such as Onedrive for business to do a sync. (not really recommended
    5. Use Azure Backup to do a protect VM which runs hourly. This will protect the attached drives as well.

    Regards,

  • CDN replication turns out to be the answer!

    Interesting use of CDN and creative thinking!!

    What would we use for figuring out the deltas? Any Azure solutions that can help with deltas?
