Backup two HD of the same KVM separately

[Vaugh]

Hi all,
I'm testing Proxmox 2.1 in my lab and I evaluating its implementation in production.

I have a WS 2003 R2 physical server and I want to migrate it in a KVM.
The user's data are all on a second HD and I use the built-in software solution of WS 2003 to backup data and system state on a NFS share.
On Proxmox I create a virtual machine with two HD (1 for OS and 1 for data).

• HD Data is 500GB with 300GB occupied.
• HD OS is 32GB with 22GB occupied.

1. Can I configure two different backup, one for the OS HD and one for data HD?
2. Is the Vzdump backup a good solution to backup the data HD or would it be better to continue to use the built-in WS2003 backup solution?

Which solution you suggest to implement?
Thanks.

I would think of using vzdump (to a NFS share) for the system disk only. set the backup=no flag to your VM config.

And use a windows backup tool for data and system state. but there are also other solutions.

Thanks for the reply tom.
So it is not possible to configure two different backup routine as I undestand.
Why do you suggest to use vzdump only for OS HD?
What problem are involved with vzmdump and an HD containing only data?

but there are also other solutions.

We can't spend money for SAN, iSCSI or hardware like that and , at the moment, we don't have a Gigabit LAN (10/100).
Which solutions do you suggest?

Thanks in advance.

you can configure as many vzdump backups as you want.

as its smaller and enough to bring the VM backup online in the case of disaster.

there is no problem. who told you this?

I already told you this. (you wrote that you got a NFS server, isn´t that true?)

I can't find an option to confirure two separate backup for two different HD in the same KVM.
Maybe I can do that only by command line?

But in my case bringing VM online with no data is useless.
Moreover I'm concerned about performance issue with the built-in backup service in WS 2003 inside a KVM.

What if I simply backup only the OS HD like you said and the DATA HD with rsync?

I already told you this. (you wrote that you got a NFS server, isn´t that true?)

Yes, it's true.
I was referring to your statement "but there are also other solutions".
I thought that you were referring to some solutions other than these I mentioned.

For windows system, there are hundreds of backup and imaging products available - there is no best solution for all situation.

vzdump can do full image backups which is great for disaster recovery, but sometimes this is not enough. e.g. no individual file restore, no system state, no differential/incremental backup, ....

Thanks Tom,
I will try some options.
Anyway it's clear that using a KVM with two hard disk it's not possible to separate the backup one for each disk.
