Forget/Prune Policies

Autorestic supports declaring snapshot policies for location to avoid keeping old snapshot around if you don't need them.

This is based on Restic's snapshots policies, and can be enabled for each location as shown below:

Note

This is a full example, of course you also can specify only one of them

version: 2

locations:
  etc:
    from: /etc
    to: local
    options:
      forget:
        keep-last: 5 # always keep at least 5 snapshots
        keep-hourly: 3 # keep 3 last hourly snapshots
        keep-daily: 4 # keep 4 last daily snapshots
        keep-weekly: 1 # keep 1 last weekly snapshots
        keep-monthly: 12 # keep 12 last monthly snapshots
        keep-yearly: 7 # keep 7 last yearly snapshots
        keep-within: '14d' # keep snapshots from the last 14 days

Globally

You can specify global forget policies that would be applied to all locations:

version: 2

global:
  forget:
    keep-daily: 30
    keep-weekly: 52

Automatically forget after backup

You can also configure autorestic to automatically run the forget command for you after every backup. You can do that by specifying the forget option.

version: 2

locations:
  etc:
    from: /etc
    to: local
    forget: prune # Or only "yes" if you don't want to prune
    options:
      forget:
        keep-last: 5
