PVE - Backups

Backups are important.

Incredibly important.

Do Your Backups!

That said, manual backups kinda suck.

& PVE backups through the Web UI are manual backups.

If you want to do automated backups, you'll do them through the CLI (Probably using cron...)

The tool PVE provides is vzdump.

Creating Backups

Some examples

Selecting which VMs to backup

• vzdump VMID

Backs up a specific VM.

• vzdump --all

Backs up ALL of the VMs on the node.

• vzdump VMID1 VMID2 VMID3

Backs up the 3 specified VMs.

Selecting WHERE to put the backups

• vzdump VMID --storage Datastore

Backs up the VM to the selected Datastore.

• vzdump VMID --dumpdir Location

Backs up the VM to a specific location on the underlying (bare-metal) filesystem.

Adding notes to the backup

• vzdump VMID --notes-template "This is a note about the backup"

You can even embed identifying information automatically into your note. (The variables: {{cluster}}, {{guestname}}, {{node}}, and {{vmid}} are available.)
