       "This package contains user-space utilities to create and inspect bcache
partitions.  It's rather minimal as bcache is designed to work well without
configuration on any system.

Linux's @acronym{bcache, block layer cache} lets one or more fast block devices,
such as flash-based @acronym{SSDs, solid state drives}, to act as a cache for
one or more slower (and inexpensive) devices, such as hard disk drives or
redundant storage arrays.  In fact, bcache intends to be a superior alternative
to battery-backed RAID controllers.

Bcache is designed around the performance characteristics of SSDs and tries to
minimize write inflation.  It's file-system agnostic and does both write-through
and write-back caching.")

       "Gpart tries to guess the partitions on a PC-style, MBR-partitioned disk
after they have been inadvertently deleted or the primary partition table at
sector 0 damaged.  In both cases, the contents of these partitions still exist
on the disk but the operating system cannot access them.

Gpart ignores the partition table and scans each sector of the device or image
file for several known file system and partition types.  Only partitions which
have been formatted in some way can be recognized.  Several file system guessing
modules are built in; more can be written and loaded at run time.

The guessed table can be restored manually, for example with @command{fdisk},
written to a file, or---if you firmly believe it's entirely correct---directly
to disk.

It should be stressed that gpart does a very heuristic job.  It can easily be
right in its guesswork but it can also be terribly wrong.  Never believe its
output without any plausibility checks.")

This package also includes the @command{photorec} command, described below.

PhotoRec is file data recovery software designed to recover lost files
including video, documents and archives from hard disks, CD-ROMs, and lost
pictures (thus the Photo Recovery name) from digital camera memory.  PhotoRec
ignores the file system and goes after the underlying data, so it will still
work even if your media's file system has been severely damaged or
reformatted.  It can recover lost files from at least:
@enumerate
@item FAT
@item NTFS
@item exFAT
@item ext2/ext3/ext4 file system

@option{-d} option, duperemove will submit those extents for deduplication
using the Linux kernel extent-same @code{ioctl}.

Duperemove can store the hashes it computes in a @dfn{hash file}.  If given an
existing hash file, duperemove will only compute hashes for those files which
have changed since the last run.  Thus you can run duperemove repeatedly on
your data as it changes, without having to re-checksum unchanged data.

Duperemove can also take input from the @command{fdupes} program.")
