Data Movement: NDMP File System Operations

This statistic shows access per second to the filesystem during NDMP backup or restore. This statistic is only meaningful for tar-based backups because they occur at the file, not block, level.

When to Check NDMP File System Operations

This can be useful to check when investigating the source of ZFS load. First, check all other sources of filesystem activity via the Protocol statistics. Also see the Advanced Analytics statistics Data Movement: NDMP Bytes Transferred to/from Disk and Data Movement: NDMP Bytes Transferred to/from Tape.
