Charter for Working Group

The Network Data Management Protocol (NDMP) defines a network-based
mechanism and protocol for controlling backup, recovery, and other
transfers of data between primary and secondary storage. The NDMP
architecture separates the network attached Data Management Application
(DMA), Data Servers and Tape Servers participating in archival or
recovery operations. NDMP also provides low-level control of tape
devices and SCSI media changers. The XDR and TCP/IP protocols are
foundations for NDMP. The key goals of NDMP include interoperability,
contemporary functionality, extensibility, internationalization,
security, and insuring data integrity.

The NDMP Working Group will enhance the protocol to provide generic
support for widely desired new features and excise the biases that
the protocol's interoperability. The NDMP Working Group provides the
forum for the discussion and advancement of the NDMP standard. The
objective of this NDMP Working Group is to advance the state of NDMP
standards by producing a version 5 specification and other NDMP version
5 standardization and protocol efforts, including a standard version 5
extensions document.

NDMP version 5 will be submitted as an Internet Standards Track RFC.
first phase of working group activity is to produce a new requirements
document for NDMP version 5. Such a requirements document will
the limitations and deficiencies of current NDMP versions, propose
level solutions for improvements, and rate the importance of different
solutions. Following the publication of this document, work will begin
on producing version 5 of the NDMP specification. It is anticipated
NDMP version 5 will emphasize the following features:

Restartability and Checkpoints
Improved Authentication
Firewall Compatibility
Generalization for Non-UNIX Environments
Data Management of Data Sets Beyond File Systems
Snapshot Management
Multi-source or Multi-destination Sessions
Standardization of Environment Variables

Further information on these objectives can be found in the document,
"Requirements for Network Data Management Protocol Version 5."
