NAME¶
systemd.snapshot - Snapshot unit configuration
SYNOPSIS¶
snapshot.snapshot
DESCRIPTION¶
Snapshot units are not configured via unit configuration files. Nonetheless they
are named similar to filenames. A unit whose name ends in
".snapshot" refers to a dynamic snapshot of the systemd runtime
state.
Snapshots are not configured on disk but created dynamically via
systemctl
snapshot (see
systemctl(1) 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
systemctl
isolate. They are useful to roll back to a defined state after temporarily
starting/stopping services or similar.
