+### Recommended options

+
+# Tarsnap key file
+keyfile /root/.tarsnap.key
+
+# Don't archive files which have the nodump flag set

+
+# Print statistics when creating or deleting archives
+print-stats
+
+# Create a checkpoint once per GB of uploaded data.
+checkpoint-bytes 1G
+
+### 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.

+# 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.

+# 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.

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