  ### Recommended options

  # Tarsnap cache directory
  cachedir /home/grfn/.cache/tarsnap

  # Tarsnap key file
  keyfile /home/grfn/.private/tarsnap.key

  # Don't archive files which have the nodump flag set.
  nodump

  # Print statistics when creating or deleting archives.
  print-stats

  # Create a checkpoint once per GB of uploaded data.
  checkpoint-bytes 1G

  ### Commonly useful options

  # Use SI prefixes to make numbers printed by --print-stats more readable.
  humanize-numbers

  ### Other options, not applicable to most systems

  # Aggressive network behaviour: Use multiple TCP connections when
  # writing archives.  Use of this option is recommended only in
  # cases where TCP congestion control is known to be the limiting
  # factor in upload performance.
  #aggressive-networking

  # Exclude files and directories matching specified patterns.
  # Only one file or directory per command; multiple "exclude"
  # commands may be given.
  #exclude

  # Include only files and directories matching specified patterns.
  # Only one file or directory per command; multiple "include"
  # commands may be given.
  #include

  # Attempt to reduce tarsnap memory consumption.  This option
  # will slow down the process of creating archives, but may help
  # on systems where the average size of files being backed up is
  # less than 1 MB.
  #lowmem

  # Try even harder to reduce tarsnap memory consumption.  This can
  # significantly slow down tarsnap, but reduces its memory usage
  # by an additional factor of 2 beyond what the lowmem option does.
  #verylowmem

  # Snapshot time.  Use this option if you are backing up files
  # from a filesystem snapshot rather than from a "live" filesystem.
  #snaptime <file>
