Hello,

I have used many of these tools and if there is a failure to create a VMware Snapshot (not any other form of snapshot) then that is usually a failure in the tool understanding a response, a snapshot may already exist, lack of space within your environment to create such a snapshot, or you are using a non-virtual Raw Disk Map. non-virtual RDMs require traditional backup/restore approaches.

If it was me, instead of looking at a new tool that may have the same issue, look at the reason for the snapshot creation failure. If you can find the root cause you can solve the problem and it will be solved going forward. If you are out of diskspace on a given VMFS and as such should probably specify another LUN to store the snapshot (also possible). If you are using a non-virtual RDM convert it to Virtual (which may require a reboot of the VM). If it is any other reason then it will take some debugging. Some older tools may also have issues if other snapshots exist.

However, if you rather not do that work there are several new tools on the market that perform replication without the need for snapshots. Those would be ZeRTO and the soon to be out VMware Replication. Granted they only work for running VMs, but that may be sufficient for your needs. These tools tie into the vSCSI layer and as such replicate data as it goes towards the backend array.
