I'm in the process of configuring Veaam Backup v5 and is trying out the replication feature to see if it's a better solution than using EqualLogic replication. Veeam Backup has the option to backup and replicate "continuously", which would mean that data is replicated as soon as possible.
Wouldn't this keep a live snapshot constantly on the datastore, or force a lot of create/remove snaphot operations? Won't that hurt datastore performance a lot to have snapshots on there all the time for alle VM's? I'm no expert but have read a lot about some locking that occurs whenever as snapshot is present on a VM on a datastore.

An updated review from InfoWorld about New EqualLogic firmware takes a load off VMware
That's why, but still don't over use it.Another VMware-only feature in version 5 is hardware-assisted locking. Normally, when VMware conducts certain operations -- such as powering a virtual machine on or off, executing a VMotion, creating a new virtual machine, or deleting a snapshot -- the entire VMFS file system is locked momentarily. When these actions occur sporadically, it's not much of a problem, but when there's a run on the VMware farm -- such as when a bunch of new VDI desktops are powered on -- it can create delays. In this new firmware version, EqualLogic arrays can lock only the blocks required to perform that operation, allowing the VMFS file system to continue to serve other requests. Thus, there are no delays felt by concurrent operations, which can help significantly when the file system is getting hammered.
I've also written a summary about Veeam Backup & Replication v5 and ESX VAAI with Equallogic Array in my blog.

Still having some ressearch done about veeam utilisation.
I'm wondering in which case it is good to have continous backup/replication?
In my opinion you should have good storage i/o's behind.
In my case I have to physical esxi servers without shared storage, eveything goes over copper link.
I guess it is not best practise to put continous replication in this case.
Would it result in performance issues?
Thanks a lot for your answers.
