The FSImage contains the most critical metadata in the whole HDFS cluster.
As an administrator of HDFS I'd like guidance on how to keep this metadata safe even in the event of a failure.
This could be in the form of docs explaining where this data is stored and how it might be backed up.
We can, however, also offer a more integrated solution that somehow automatically backs the data up.
