It should automatically start writing NN data to that dir. If its still
empty, you should check the NN logs and permissions on the backup dir.

Thank you. I added another directory the following configuration and
restarted my cluster:
property
namedfs.name.dir/name
value/var/hadoop/dfs/name,/var/hadoop/dfs/name.backup/value
/property
However the name.backup directory is empty. Is there anything I need to
do to tell it to backup?
Hey Mark,
If you add more than one directory (comma separated) in the variable
dfs.name.dir it would automatically be copied in all those location.

How would I go backing up our namenode data? I set up the
secondarynamenode on a separate physical machine but just as a backup I
would like to save the namenode data.
Thanks
