Replication and backup sulution

Hello Experts.

I have been trying out a lot of the solutions mensioned in a previous question.

Like Veaam, Acronis, vRanger and even doubletake.

They all use the snapshot technology provided bij Vmware.

In a replication solution this leads to big cycle times (2-3 hours over a 20Mbit wan).

I am looking for a more continues solution with a lot shorter cycle time.
If more information changes as can be uploaded a buffer should hold the information.

I think this is called "near realtime"

Are there solutions that work like a "raid1 over wan"?

use SAN snapshots, and Mirror Between SANs or wait for vSphere Replication in vSphere 5.1 to be released next week!

You could also use HP Lefthand VSA SANs that perform RAID level functions between SAN nodes.p

Any solution that you have will ultimately depend on the amount of changes versus throughput.  SAN replication usually works best since it will do this at block level.  Do you have a SAN solution? If so what type?

and every solution will dependent on your wan link. great solutoins and products can deliver worst RTO, RPO, if design is not done correctly.

We have no san at the moment as the company is relatively small.

Can you give a  type of san and what a solution like this would cost?

It's great to talk about it,  and wish it to work, but they are never going to spend more than euro 2000-2500 for the solution, is this wishfull thinking then?

i understand there will be 2 sans necessary, one on the source and one on the destination side. and that the sans them selves take care of the replication becouse they cab be configured as a raid1 combination.

Hanccocka: Maybe trying Vmware 5.1 is a more cost effective solution (does it work with the 5.1-I version also?)

No SAN required for Replication, between Virtual Hosts, just local storage required.

and Veeam Backup and Replication.

If you want realtime, sync between sites, you are looking at a budget of approx 50k euros, or two SANs, or Clustered SANs.

You need to work out, what budget you have, and what you can afford for DR, Sync, Replication for your business.

ok thanks, one more question.

The Vmware 5.1 replication is also based on snapshot technology from Vmware?
