long term backup of virtual machines that are replicated via HyperV on-prem to azure

Hello,

I have set up a replication from on-prem to azure, I am able to do a failover and that is ok, but the problem is I do not see any way to do a backup of that replication. For example, keeping a daily snapshot for a week, if that is that even possible in azure?

The reason I need this is that I also need to cover disaster recovery scenarios that include ransomware and data loss, If I cannot select a recovery point prior to a ransomware attack, that makes the replication useless for that scenario.

Many thanks,
Krys

    Hi Krystian Blaszkowicz,

    Thanks for posting your question in the Microsoft Q&A forum

    Azure Site Recovery is designed for disaster recovery, not long-term backup. It allows you to retain recovery points for up to 15 days if you're using Managed Disks, and only 3 days with Unmanaged Disks.

    This means if you need to restore to a point older than 15 days, ASR alone won’t help.

    For long-term retention and proper recovery, you should use a backup solution, such as:

    • Azure Backup for virtual machines running in Azure
    • Microsoft Azure Backup Server for on-premises Hyper-V VMs
    • Or third-party tools like Veeam or Rubrik

    ASR is useful for quick recovery from outages or failures, but not for keeping daily, weekly, or monthly snapshots.
