# 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
