Stupid question... confused about backup/restore?

[amelsen]

Situation:

Several virtual machines created - all backed up to secondary storage.. Ie. a NAS fx.

proxmox server disk crashes, new disk retriever, proxmox reinstalled and now to get all kvm virtual machines up and running again.

KVM Machine 1: Used to be stored locally and run from there.
KVM Machine 2: Virtual disk placed on another storage


Now.. the wiki says this:

Restore with vzrestore and qmrestore

To restore a Virtual Machine, just copy the tar file to the host where you want to restore. Depending on the type of virtual machine, use 'vzrestore' to restore OpenVZ containers, or 'qmrestore' to restore KVM machines.
Example1: Restore the backup of KVM VM 555 (backup file: vzdump-qemu-555.tar) to CT 500
qmrestore vzdump-qemu-555.tar 500

Alright... so I copy the two .tar files to the newly installed proxmox installation..

if I type 'qmrestore vzdump-qemu-555.tar 500'
- how precisely is this machine launched again?
- where will it be placed?
- what does the number '500' in the end indicate? CT 500?? What is CT the abbreviation off.

As I could read, it would normally be restored to the original location.. but that can only be done if storage volumes are created exactly like they used to be, and with the same names? or?

The --storage option... is the parameter the actual storage NAME, or?

I guess I'm just a bit confused on how this works...

.. And final question... is there any way to do a full configuration backup of the proxmox server? I mean.. if several volumes and various other things have been configured.. it would be nice to have a configuration backup/restore function so IF the specific server crashes, that there is an easy way to reinstall it and get the exact same configuration back...

Looking forward to hearing an answer. Thanks alot.

all commands have man pages, just run 'man qmrestore' to see the options.
CT stands for the VMID (virtual machine id) - must be unique.

yes, the name you defined on the admin interface: Configuration/Storage: Storage name

there is no special built in backup feature for the host itself, just take a common backup software available for Debian Lenny 64-bit - there are a lot of them around.
