6 restic-forget - Remove snapshots from the repository
7
11 restic forget [flags] [snapshot ID] [...]
12
16 The "forget" command removes snapshots according to a policy. All snap‐
17 shots are first divided into groups according to "--group-by", and af‐
18 ter that the policy specified by the "--keep-*" options is applied to
19 each group individually.
20 Please note that this command really only deletes the snapshot object
23 in the repository, which is a reference to data stored there. In order
24 to remove the unreferenced data after "forget" was run successfully,
25 see the "prune" command.
26 Please also read the documentation for "forget" to learn about some im‐
29 portant security considerations.

35 was any error.
