[raja kamran]

Dear all,

I need info regarding backup of VMS, I have installed DP 6.0 with three licenses

1. On-line extension for one windows / Linux system ( qty: 1)

2. Cell Manager and single drive for windows / linux / netware (qty: 1)

3. Tap drive for SAN / all platforms (qty: 2)

Now i wanna go for DP 6.11 and wanna take backup of 33 Virtual machines which are on VMware ESX 4.1 with one Vcenter and 4 host machines.

Which licenses are need to be purchased.

Regards,
