While Taking Backup m getting this error...please help me out.

The path /es/backup/betabackup needs to be accessible by all nodes in the cluster.

how can i access my all nodes in cluster??please help me ??

Typically one uses NFS to share a directory between all nodes (but any networked file system should do). The NFS server can either be one of the cluster nodes or a separate server or appliance.
