13 +From here we implement the following storage strategy 3-2-2:
12 12  
13 -== Sub-paragraph ==
15 + - Maintain 3 copies: 1 local, 1 off-site and 1 cloud copy.
16 + - Use 2 different storage media: HDD on both sites and Cloud storage
17 + - Keep 2 copies off site: secondary datacenter and Cloud.

19 +This modifies the original rule a bit:
20 + - 3 copies of data
21 + - on 2 different media
22 + - with 1 copy being off-site

26 +We run most all our services with proxmox. It comes with a companion software proxmox backup server that is used to backup all resources on interval. All virtual machines and LXC containers running in our infra are then managed by [[Proxmox Backup server>>proxmox.Backup.WebHome]]. Every night snapshot are taken at between 02-05 from all [[servers>>servers.WebHome]] hosts.

34 +To ensure backups are not lost if the entire local datacenter is lost we want to syncronize all backups to an off-site location. Syncthing is used to duplicate everything on local proxmox backup server.
