|

|
|
When a dataset is rolled back, all data that has changed since the snapshot is
|
||
|
|
discarded, and the dataset reverts to the state at the time of the snapshot.
|
||
|
|
By default, the command refuses to roll back to a snapshot other than the most
|
||
|
|
recent one.
|
||
|
|
In order to do so, all intermediate snapshots and bookmarks must be destroyed by
|
||
|
|
specifying the
|
||
|
|
.Fl r
|
||
|
|
option.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Fl rR
|
||
|
|
options do not recursively destroy the child snapshots of a recursive snapshot.
|
||
|
|
Only direct snapshots of the specified filesystem are destroyed by either of
|
||
|
|
these options.
|
||
|
|
To completely roll back a recursive snapshot, you must rollback the individual
|
||
|
|
child snapshots.
|
||
|
|
.Bl -tag -width "-R"
|
||
|
|
.It Fl R
|
||
|
|
Destroy any more recent snapshots and bookmarks, as well as any clones of those
|
||
|
|
snapshots.
|
||
|
|
.It Fl f
|
||
|
|
Used with the
|
||
|
|
.Fl R
|
||
|
|
option to force an unmount of any clone file systems that are to be destroyed.
|
||
|
|
.It Fl r
|
||
|
|
Destroy any snapshots and bookmarks more recent than the one specified.
