Constructor Details

#initialize(target_dir, config_dir: Pathname.new('/etc/snapper/configs'), autoclean: nil) ⇒ SyncAll

Creates a sync-all operation for the given target directory

Parameters:

  • target_dir (Pathname) —

    the target directory

  • autoclean (Boolean, nil) (defaults to: nil) —

    if true or false, will control whether the targets should be cleaned of obsolete snapshots after synchronization. If nil (the default), the target’s own autoclean flag will be used to determine this
