How can I back up my VMs without slowing them down?

[GMer]

Hi everyone!
I’m trying to figure out the best way to back up several VMs and containers in Proxmox. I’d like to do it without slowing down the running machines or causing issues for users. Do you have any tips or strategies that work well? Are live backups with snapshots the way to go, or is there a better approach?
Thanks!

You may want to enable "Backup fleecing", which directs writes during the backup to a local fast image to avoid slowing down guests: https://pve.proxmox.com/wiki/Backup_and_Restore#_backup_modes
