Snapshots using veeam and vmware 4.1

I want to replicate one servers every 15 minutes or so.  Problem is, using products such as veeam or vranger uses the snapshot technology built into vcenter to accomplish this, which results in continuous snaps tying and deleting of snapshots.   Seems to me this would put a burden on the host server,  

Any alternatives?  Any methods that don't rely on snapshots?  The ones that do snapshots, any way to miminize impact on the hosts ?

Any VM backup or Replication technology uses snapshots; it has to so it can capture any data written to the VM concurrently during the b/u or replication. If there is a solution that doesn't use snapshotting (outside of doing a manual VM clone or copy), I'm not aware of it.

Snapshots and using the VMware API is the only way to take the lock off the main diskfile, vmdk, to replicate/copy the data.

All third party backup products and VMware vDR using the Snapshot technology.

This shouldn't cause a performance issue, or burden on the host server, when the snapshot is created the data is just written to another delta file.

However, it does depend upon the load of the virtual server, and how busy a virtual machine it is.

Alternatives, exist, at the SAN Snapshot level, which doesn't burden the Host ESX server, because the SAN creates the SAN snapshot, and uses technology to replicate the SAN snapshot via Snap Mirror (NetApp technology) to the DR site.

It does not affect the VM. (but these are crash consistent). If you want true non-crash consistent VMs you need to quiecse the virtual machine, which requires a Snapshot of the VM.
