  36. .Sh NAME
  37. .Nm zfs-rollback
  38. .Nd roll ZFS dataset back to snapshot
  39. .Sh SYNOPSIS
  40. .Nm zfs
  41. .Cm rollback
  42. .Op Fl Rfr
  43. .Ar snapshot
  44. .
  45. .Sh DESCRIPTION
  46. When a dataset is rolled back, all data that has changed since the snapshot is
  47. discarded, and the dataset reverts to the state at the time of the snapshot.
  48. By default, the command refuses to roll back to a snapshot other than the most
  49. recent one.
  50. In order to do so, all intermediate snapshots and bookmarks must be destroyed by
  51. specifying the
  52. .Fl r
  53. option.
  54. .Pp
  55. The
  56. .Fl rR
  57. options do not recursively destroy the child snapshots of a recursive snapshot.
  58. Only direct snapshots of the specified filesystem are destroyed by either of
  59. these options.
  60. To completely roll back a recursive snapshot, you must roll back the individual
  61. child snapshots.
  62. .Bl -tag -width "-R"
  63. .It Fl R
  64. Destroy any more recent snapshots and bookmarks, as well as any clones of those
  65. snapshots.
  66. .It Fl f
  67. Used with the
  68. .Fl R
  69. option to force an unmount of any clone file systems that are to be destroyed.
  70. .It Fl r
  71. Destroy any snapshots and bookmarks more recent than the one specified.
