Backup Architecture

Hi,

I have a vCenter that I need to backup in our office. All up its about 500GB of used space, 2 hosts with 5 VMs.

We are looking for a solution where we can backup offsite (to another site) overnight, where we will have a device that will store the backup. The connection between the sites is 8m/8m.

What I want to know is what is the best way to do this, obviously the first backup I would have to do onsite (as it would be a bit big for 8m link) and then move off.

Has anyone done this before? I was reading that you can get applicatons that backup at the block level, so I would like to use somthing like this.

Ideally I would love to hear from people who have done a similar thing before. (upgrading the bandwidth isn't an option)

Thanks

Mark

Netbackup can do this, it you can do this via the SLP policies and this can be deduped so you minimize the replication windows/size

I would recommend Veeam Backup and Replication v7, with new WAN replication features.
http://www.veeam.com/vmware-esx-backup.html

You can pre-seed the server, at the DR (destination) end, and then replicate the delta on a daily basis.

You can also use this article, so you can determine your delta size...

Ok, so would an 8m connection be enough do you think?

it depends on the rate of change of Virtual Machines, during the day.

Use the articles, I've posted, to work out, you daily change rate, with Veeam, you can initially seed, and then use Incrementals backups on a daily basis.

Also consider using a D2D backup appliance with deduplication.  EMC has one (look for Data Domain products) and HP also has one (HP StoreOnce D2D Backup System) that works particularly well with Veeam.

Because they use deduplication, you only store and replicate unique blocks, so after the initial on-site replication over GbE, you can move the remote appliance and only have to replicate the 'new' blocks.
