The xfsdump package contains xfsdump, xfsrestore, and a number of other
utilities for administering XFS file systems.

xfsdump examines files in a file system, determines which files need to
be backed up, and copies those files to a specified disk, tape, or
other storage medium. It uses XFS-specific directives for optimizing
the dump of an XFS file system and also knows how to backup XFS
extended attributes. Backups created with xfsdump are "endian safe"
and can thus be transferred between Linux machines of different
architectures and also between IRIX machines.

xfsrestore performs the inverse function of xfsdump. It can restore a
full backup of a file system. Subsequent incremental backups can then
be layered on top of the full backup. Single files and directory
subtrees may be restored from full or partial backups.

A set of commands to use the XFS file system, including mkfs.xfs.

XFS is a high performance journaling file system which originated on
the SGI IRIX platform. It is completely multithreaded. It can support
large files and large file systems, extended attributes, and variable
block sizes.It is extent based and makes extensive use of Btrees
(directories, extents, and free space) to aid both performance and
scalability.

Refer to the documentation at http://oss.sgi.com/projects/xfs/ for
complete details. This implementation is on-disk compatible with the
IRIX version of XFS.

The NeoMutt Project is hoping to kick-start development on the Mutt project.

Dstat is a versatile replacement for vmstat, iostat, netstat and ifstat.
Dstat overcomes some of their limitations and adds some extra features,
more counters and flexibility. Dstat is handy for monitoring systems
during performance tuning tests, benchmarks or troubleshooting.

Dstat allows you to view all of your system resources instantly, you
can eg. compare disk usage in combination with interrupts from your
IDE controller, or compare the network bandwidth numbers directly
with the disk throughput (in the same interval).

Dstat gives you detailed selective information in columns and clearly
indicates in what magnitude and unit the output is displayed. Less
confusion, less mistakes.
