vzdump

Backup Utility for virtual machines and containers. More information: https://pve.proxmox.com/pve-docs/vzdump.1.html.

  • Dump a guest virtual machine into the default dump directory (usually /var/lib/vz/dump/), excluding snapshots:

vzdump vm_id

  • Back up the guest virtual machines with the IDs 101, 102, and 103:

vzdump 101 102 103

  • Dump a guest virtual machine using a specific mode:

vzdump vm_id --mode suspend|snapshot

  • Back up all guest systems and send an notification email to the root and admin users:

vzdump --all --mode suspend --mailto root --mailto admin

  • Use snapshot mode (no downtime required) and a non-default dump directory:

vzdump vm_id --dumpdir path/to/directory --mode snapshot

  • Back up all guest virtual machines excluding the IDs 101 and 102:

vzdump --mode suspend --exclude 101, 102
