+
+  # 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.

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

+  # 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.
