<title>Description</title>
|
|
|
|
<para>Snapshot units are not configured via unit
|
|
configuration files. Nonetheless they are named
|
|
similar to filenames. A unit name whose name ends in
|
|
<filename>.snapshot</filename> refers to a dynamic
|
|
snapshot of the systemd runtime state.</para>
|
|
|
|
<para>Snapshots are not configured on disk but created
|
|
dynamically via <command>systemctl snapshot</command>
|
|
(see
|
|
<citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
|
for details) or an equivalent command. When created,
|
|
they will automatically get dependencies on the
|
|
currently activated units. They act as saved
|
|
runtime state of the systemd manager. Later on, the
|
|
user may choose to return to the saved state via
|
|
<command>systemctl isolate</command>. They are
|
|
useful to roll back to a defined state after
|
|
temporarily starting/stopping services or
|
|
similar.</para>
