Ciao, ho un problemino che vorrei risolvere.
Sotto Proxmox ho virtualizzato una macchina KVM con 3 dischi virtuali.
La mia domanda è questa: è possibile, tramite vzdump, escludere due
dei tre dischi dal backup
(i due dischi da escludere contengono dati che NON voglio "backuppare") ?
questa è la versione attuale della mia proxmox:
pveversion -v
pve-manager: 1.5-10 (pve-manager/1.5/4822)
running kernel: 2.6.32-2-pve
proxmox-ve-2.6.32: 1.5-7
pve-kernel-2.6.32-2-pve: 2.6.32-7
pve-kernel-2.6.24-10-pve: 2.6.24-21
pve-kernel-2.6.18-2-pve: 2.6.18-5
qemu-server: 1.1-16
pve-firmware: 1.0-5
libpve-storage-perl: 1.0-13
vncterm: 0.9-2
vzctl: 3.0.23-1pve11
vzdump: 1.2-5
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.12.4-1
ksm-control-daemon: 1.0-3
questi sono i comandi che uso:
vzdump --node 1 --snapshot --compress --storage backup 400
ho provato a usare il parametro --exclude-path
vzdump --node 1 --snapshot --compress --storage backup400
--exclude-path "/var/lib/vz/images/400/vm-400-disk-1.qcow2"
--exclude-path "/var/lib/vz/images/400/vm-400-disk-2.qcow2"
--exclude-path "/var/lib/vz/images/400/vm-400-disk-3.qcow2" 400
ma penso proprio che parametro --exclude-path funzioni solo per le
macchine OpenVZ
Questo il log che ottengo:

come si può notare vengono aggiunti al file tgz tutti e tre i dischi:

Qualsiasi suggerimento è ben accetto !
grazie mille.
