Response for Backup Service being down for an extended period of time

If our current backup service ever becomes unavailable for an extended period of time (extended being longer than our required period for making a backups), we'll have to make backups with an alternative service. The advice would be the following:

• Set up a Proxmox Backup Server VM on Pistol: https://pbs.proxmox.com/docs/installation.html
• There are unassigned disks on Pistol. Those should be assigned to the PBS VM
• Set up credentials for
  • Offsite
  • WS Cluster
  • S3 VM's
• Configure these hosts to use the newly set up PBS service

Note: Since this has likely not been done before, everything (VM's, buckets) need to have an 'initial' backup made of them. This is not a special process, but it means that ALL of their data needs to be read and transferred. This significantly more time than making the next sequential backups, so you'll want to start with making backups of the critical services, such as client VM's and buckets, and start the backups on time before any deadlines.
