63 -== Access Control ==
64 -
65 -Each client host that wants to backup their contents to the backup server should have their unique API token for authentication.
66 -
67 -API Token:
68 -
69 -* user: [[root@pam>>mailto:root@pam]]
70 -* token name: CLIENT_NAME
71 -* expire: never
72 -* enabled: true
73 -
74 -Permissions - Add a API Token Permission:
75 -
76 -* path: /datastore/proxmox-backup/CLIENT_NAME
77 -* api token: root@pam!CLIENT_NAME
78 -* role: DatastoreBackup
79 -* propagate: true
80 -
81 ->Note! The path will not be define until after the Datastore namespace is define in the steps below
82 -
83 -== Proxmox datastore ==
84 -
85 -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.
86 -
87 -=== Namespace ===
88 -
89 -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.
90 -
91 -=== Prune & Garbage collect ===
92 -
93 -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:
94 -
95 -* datastore: proxmox-backup
96 -* namespace: root
97 -* keep last: 4
98 -* keep: hourly: -
99 -* keep daily: 6
100 -* keep weekly: 3
101 -* keep monthly: 6
102 -* keep yearly: 4
103 -* max_depth: full
104 -* prune schedule: 0/6:00
105 -* enabled: true
106 -
107 -=== Verify jobs ===
108 -
109 -Current configuration is:
110 -
111 -* local datastore: proxmox-backup
112 -* namespace: root
113 -* max-depth: full
114 -* schedule: daily
115 -* skip verified: true
116 -* re-verify after: 30 days
117 -
118 -=== Permissions ===
119 -
120 -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:
121 -
122 -* path: /datastore/proxmox-backup/CLIENT_NAME
123 -* API Token: root@pam!CLIENT_NAME
124 -* Role: DatastoreBackup
125 -* Propagate: true
