The path will not be define until after the Datastore namespace is define in the steps below 73 + 74 +== Proxmox datastore == 75 + 76 +If none exists create the datastore. Ours point is named `proxmox-backup` and points to ZFS storage mounted at `/mnt/pergamum`. All references to `proxmox-backup` referes to what you named it as in the create step here. 77 + 78 +=== Namespace === 79 + 80 +Namespaces is what we will use in a datastore to separate permissions to each host. It's important to create these for the API tokens create in Access Control section above. 81 + 82 +=== Prune & Garbage collect === 83 + 84 +We don't require backups for every day of the year. Pruning lets you systematically delete older backups, retaining backups for the last given number of time intervals. There exists a fantastic simulator that can be used to experiment with different backup schedules and prune options: [[https:~~/~~/pbs.proxmox.com/docs/prune-simulator/>>https://pbs.proxmox.com/docs/prune-simulator/]]. The current configuration is: 85 + 86 +* datastore: proxmox-backup 87 +* namespace: root 88 +* keep last: 4 89 +* keep: hourly: - 90 +* keep daily: 6 91 +* keep weekly: 3 92 +* keep monthly: 6 93 +* keep yearly: 4 94 +* max_depth: full 95 +* prune schedule: 0/6:00 96 +* enabled: true 97 + 98 +=== Verify jobs === 99 + 100 +Current configuration is: 101 + 102 +* local datastore: proxmox-backup 103 +* namespace: root 104 +* max-depth: full 105 +* schedule: daily 106 +* skip verified: true 107 +* re-verify after: 30 days 108 + 109 +=== Permissions === 110 + 111 +Permissions are explained in the Access Control section above, but it can be easier to configure permissions from the datastore. Navigate to the datastore Permission tab and add API Token Permission: 112 + 113 +* path: /datastore/proxmox-backup/CLIENT_NAME 114 +* API Token: root@pam!CLIENT_NAME 115 +* Role: DatastoreBackup 116 +* Propagate: true 117 + 118 += Tailscale = 119 + 120 +Tailscale is used to create a network that uses wireguard to transparently between local and remote machines. To not require a third party a local instance of headscale is used as the tailscale login server. 121 + 122 +Setting up a connection should only require `sudo tailscale up ~-~-login-server https:~/~/TAILSCALE_SUBDOMAIN.schleppe.cloud`. 123 +To view the status: `sudo tailscale status`. 124 + 125 += Jottacloud client = 126 + 127 +Cloud backup provider used is jottacloud.

This makes it impossible to download a single file representing a VM or LXC, all files must be downloaded and imported into proxmox backup server for reconstruction. 168 + 169 +It also seems like there are a LOT of files shifting - being added and deleted.
