I was looking to do some snapshots and backups programatically via scripts around qm/pvesm, however can't seem to find the said feature in the man pages. Is there another utility I should be looking at?
backup schedules are written in /etc/pve/vzdump.cron
via the api calls /cluster/backup (more info here: https://pve.proxmox.com/wiki/Proxmox_VE_API )
you can access the api directly with 'pvesh'
