54 -== Access Control ==
55 -
56 -Each client host that wants to backup their contents to the backup server should have their unique API token for authentication.
57 -
58 -API Token:
59 -
60 -* user: [[root@pam>>mailto:root@pam]]
61 -* token name: CLIENT_NAME
62 -* expire: never
63 -* enabled: true
64 -
65 -Permissions - Add a API Token Permission:
66 -
67 -* path: /datastore/proxmox-backup/CLIENT_NAME
68 -* api token: root@pam!CLIENT_NAME
69 -* role: DatastoreBackup
70 -* propagate: true
71 -
72 ->Note! 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
