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}}
