vzdump

Backup Utility for virtual machines and containers.

=> More information.

• 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}
