Maximum number of simultaneous backups in ESX?

I would like to know if anyone has any real world data on number of VM's per ESX and backing them up via an agent (normal backups through the windows OS). A lot has been made about sharing 20-30 VMs across the 3 Nics of an ESX server and the possible contention that will be there during a backup window if you try to do them all at once. Does anyone out there back up this way (not with VCB or snaps etc) and have a max number that they've discovered? Granted this will vary depending on the product, we're using HP Dataprotector, but I'm just trying to get a general feel here.

Taking backup of all your VMs at once sounds like a bad idea unless you have a lot of LUNs or a very good performing SAN that can deliver that amount of data at once.

Hi

To backup 20-30 VMs? To have a multi-backup environment you need to have dedicated FC between the Storage, and the tape drive

If you do not have this, you will risk that in the Monday morning you still have the Backup running

The rest, i think the above answer(meyersd) give a good explanation
