See #Automatic timeline snapshots for how timeline snapshots work and see #Pre/post snapshots on how pre and post work. For example, to create a snaphot that uses the number algorithm for cleanup do: number sets snapper to periodically remove snapshots that have exceeded a set number in the configuration file. To set a cleanup algorithm, use the -c flag after create and choose either number, timeline, pre, or post. The above command does not use any cleanup algorithm, so the snapshot is stored permanently or until deleted. # snapper -c config create -description desc To take a snapshot of a subvolume manually, do: See systemd/Timers and systemd#Drop-in files.Д«y default snapper takes snapshots that are of the single type, having no special relationship to other snapshots. To make cleanups occur every hour instead of every day, add: When editing snapper-cleanup.timer, you need to change OnUnitActiveSec. If you are using the provided systemd timers, you can edit them to change the snapshot and cleanup frequency.ДЇor example, when editing the snapper-timeline.timer, add the following to make the frequency every five minutes, instead of hourly: TIMELINE_LIMIT_YEARLY='0' Change snapshot and cleanup frequencies etc/snapper/configs/ config TIMELINE_MIN_AGE='1800' Here is an example section of a configuration named config with only 5 hourly snapshots, 7 daily ones, no monthly and no yearly ones: You may want to change this in the configuration, especially on busy subvolumes like /. The default settings will keep 10 hourly, 10 daily, 10 monthly and 10 yearly snapshots.

If you wish to disable cron integration while using the systemd units, one possible solution is not to install the snapper package's cron files via pacman's NoExtract and NoUpgrade configuration options. Note: If you have a cron daemon and also enable the systemd units, this may result in duplicate snapshots being created. Additionally, start and enable snapper-cleanup.timer to periodically clean up older snapshots. Start and enable snapper-timeline.timer to start the automatic snapshot timeline. If you do not have a cron daemon, you can use the provided systemd units. To disable it, edit the configuration file corresponding with the subvolume you do not want to have this feature and set: If you have a cron daemon, this feature should start automatically. Refer to the TIMELINE_* variables in snapper-configs(5) for details. Once a day the snapshots get cleaned up by the timeline cleanup algorithm. When the timeline is enabled, by default a snapshot gets created once an hour. Taking snapshots Automatic timeline snapshotsДЄ snapshot timeline can be created with a configurable number of hourly, daily, weekly, monthly, and yearly snapshots kept. If you do not use a cron daemon, you will need to use the systemd service and timer. If your cron daemon is running, snapper will take #Automatic timeline snapshots. Add config to SNAPPER_CONFIGS in /etc/conf.d/snapper.ДЇor example, to create a configuration file for the subvolume mounted at /, run:ДЄt this point, the configuration is active.

A snapshot's path is /path/to/subvolume/.snapshots/ #/snapshot, where # is the snapshot number. Create a subvolume at /path/to/subvolume/.snapshots where future snapshots for this configuration will be stored.Create a configuration file at /etc/snapper/configs/ config based on the default template from /usr/share/snapper/config-templates.# snapper -c config create-config /path/to/subvolume To create a new snapper configuration named config for the Btrfs subvolume at /path/to/subvolume, run: If it does not, you should create it before generating a snapper configuration.
