ASR Data change rate is beyond supported limits

If you see the event “Data change rate beyond supported limits” in the ASR replicated items logs, you probably need to change the disk type of your managed disks for that Virtual Machine.

I would advise waiting a bit to check if the error disappears or remains consistent.

To change the disk size go to:

  • Disks
  • Select the disk specified in the error message above
  • Click on Configuration
  • Under Account type switch from “Standard HDD” to “Premium SSD” (or “Standard SSD”)
  • Save

Cannot enable protection for a VM in ASR “This operating system isn’t supported in Azure”

If you get the following error, please check if the OS and kernel versions are supported:

If they are supported, you can install manually the agent on the VM. If it doesn’t work, try checking if the VM in VMware is configured as “Other (64-bit)” in the guest OS version. If it is, you should change the version to the specific Linux distribution you got installed. Mind that the VM must be shut off to change the Guest OS version.

To install manually the agent follow these steps:

  • Go under %ProgramData%\ASR\home\svsystems\pushinstallsvc\repository in your ASR server and copy the “Microsoft-ASR_UA*_GA*.tar.gz” file specific to your distribution.
  • Copy the file to the VM. I would recommend creating a specific folder for the file under /tmp
  • Copy the Conf server passphrase to the server
  • Unpack the file: tar -xvf Micorosft-ASR_UA_yourfile.tar.gz
  • Run the following command as root: ./install -d /usr/local/ASR -r MS -v VmWare -q
  • Register the mobility service to the Conf server: /usr/local/ASR/Vx/bin/ -i ConfserverIP -P /var/passphrase.txt
