.Sh EXAMPLES
.\" These are, respectively, examples 3, 10, 15 from zfs.8
.\" Make sure to update them bidirectionally
.Ss Example 1 : No Creating and Destroying Multiple Snapshots
The following command creates snapshots named
.Ar yesterday No of Ar pool/home
and all of its descendent file systems.
Each snapshot is mounted on demand in the
.Pa .zfs/snapshot
directory at the root of its file system.
The second command destroys the newly created snapshots.
.Dl # Nm zfs Cm snapshot Fl r Ar pool/home Ns @ Ns Ar yesterday
.Dl # Nm zfs Cm destroy Fl r Ar pool/home Ns @ Ns Ar yesterday
.
.Ss Example 2 : No Promoting a ZFS Clone
The following commands illustrate how to test out changes to a file system, and
then replace the original file system with the changed one, using clones, clone
promotion, and renaming:
.Bd -literal -compact -offset Ds
.No # Nm zfs Cm create Ar pool/project/production
populate /pool/project/production with data
.No # Nm zfs Cm snapshot Ar pool/project/production Ns @ Ns Ar today
.No # Nm zfs Cm clone Ar pool/project/production@today pool/project/beta
make changes to /pool/project/beta and test them
.No # Nm zfs Cm promote Ar pool/project/beta
.No # Nm zfs Cm rename Ar pool/project/production pool/project/legacy
.No # Nm zfs Cm rename Ar pool/project/beta pool/project/production
once the legacy version is no longer needed, it can be destroyed
.No # Nm zfs Cm destroy Ar pool/project/legacy
.Ed

.Ss Example 3 : No Performing a Rolling Snapshot
The following example shows how to maintain a history of snapshots with a
consistent naming scheme.
To keep a week's worth of snapshots, the user destroys the oldest snapshot,
renames the remaining snapshots, and then creates a new snapshot, as follows:
.Bd -literal -compact -offset Ds
.No # Nm zfs Cm destroy Fl r Ar pool/users@7daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@6daysago No @ Ns Ar 7daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@5daysago No @ Ns Ar 6daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@4daysago No @ Ns Ar 5daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@3daysago No @ Ns Ar 4daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@2daysago No @ Ns Ar 3daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@yesterday No @ Ns Ar 2daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@today No @ Ns Ar yesterday
.No # Nm zfs Cm snapshot Fl r Ar pool/users Ns @ Ns Ar today
