restic-forget - Remove snapshots from the repository
|
|
|
|
|
|
.SH SYNOPSIS
|
|
.PP
|
|
\fBrestic forget [flags] [snapshot ID] [...]\fP
|
|
|
|
|
|
.SH DESCRIPTION
|
|
.PP
|
|
The "forget" command removes snapshots according to a policy. All snapshots are
|
|
first divided into groups according to "--group-by", and after that the policy
|
|
specified by the "--keep-*" options is applied to each group individually.
|
|
|
|
.PP
|
|
Please note that this command really only deletes the snapshot object in the
|
|
repository, which is a reference to data stored there. In order to remove the
|
|
unreferenced data after "forget" was run successfully, see the "prune" command.
|
|
|
|
.PP
|
|
Please also read the documentation for "forget" to learn about some important
|
|
security considerations.
|
|
|
|
|
|
.SH EXIT STATUS
|
|
.PP
|
|
Exit status is 0 if the command was successful, and non-zero if there was any error.
