-6 Lziprecover
-*************
-
-Lziprecover is a data recovery tool for lzip compressed files able to
-repair slightly damaged files, recover badly damaged files from two or
-more copies, and extract undamaged members from multi-member files.
-
-   Lziprecover takes as arguments the names of the damaged files and
-writes zero or more recovered files depending on the operation selected
-and whether the recovery succeeded or not. The damaged files themselves
-are never modified.
-
-   If the files are too damaged for lziprecover to repair them, data
-from damaged members can be partially recovered writing it to stdout as
-shown in the following example (the resulting file may contain garbage
-data at the end):
-
-     lzip -cd rec00001file.lz > rec00001file
-
-   If the cause of file corruption is damaged media, the combination GNU
-ddrescue + lziprecover is the best option for recovering data from
-multiple damaged copies. *Note ddrescue-example::, for an example.

-7 Invoking Lziprecover
-**********************
-
-The format for running lziprecover is:
-
-     lziprecover [OPTIONS] [FILES]
-
-   Lziprecover supports the following options:
-
-`-h'
-`--help'
-     Print an informative help message describing the options and exit.
-
-`-V'
-`--version'
-     Print the version number of lziprecover on the standard output and
-     exit.
-
-`-f'
-`--force'
-     Force overwrite of output file.
-
-`-m'
-`--merge'
-     Try to produce a correct file merging the good parts of two or more
-     damaged copies. The copies must be single-member files. The merge
-     will fail if the copies have too many damaged areas or if the same
-     byte is damaged in all copies. If successful, a repaired copy is
-     written to the file `FILE_fixed.lz'.
-
-     To give you an idea of its possibilities, when merging two copies
-     each of them with one damaged area affecting 1 percent of the
-     copy, the probability of obtaining a correct file is about 98
-     percent. With three such copies the probability rises to 99.97
-     percent. For large files with small errors, the probability
-     approaches 100 percent even with only two copies.
-
-`-o FILE'
-`--output=FILE'
-     Place the output into `FILE' instead of into `FILE_fixed.lz'.
-
-     If splitting, the names of the files produced are in the form
-     `rec00001FILE', etc.
-
-`-q'
-`--quiet'
-     Quiet operation. Suppress all messages.
-
-`-R'
-`--repair'
-     Try to repair a small error, affecting only one byte, in a
-     single-member FILE. If successful, a repaired copy is written to
-     the file `FILE_fixed.lz'. `FILE' is not modified at all.
-
-`-s'
-`--split'
-     Search for members in `FILE' and write each member in its own
-     `.lz' file. You can then use `lzip -t' to test the integrity of
-     the resulting files, decompress those which are undamaged, and try
-     to repair or partially decompress those which are damaged.
-
-     The names of the files produced are in the form `rec00001FILE.lz',
-     `rec00002FILE.lz', etc, and are designed so that the use of
-     wildcards in subsequent processing, for example,
-     `lzip -cd rec*FILE.lz > recovered_data', processes the files in
-     the correct order.
-
-`-v'
-`--verbose'
-     Verbose mode. Further -v's increase the verbosity level.

-
-Lziprecover is a data recovery tool for lzip compressed files able to
-repair slightly damaged files, recover badly damaged files from two or
-more copies, and extract undamaged members from multi-member files.
-
-Lziprecover takes as arguments the names of the damaged files and writes
-zero or more recovered files depending on the operation selected and
-whether the recovery succeeded or not. The damaged files themselves are
-never modified.
-
-If the files are too damaged for lziprecover to repair them, data from
-damaged members can be partially recovered writing it to stdout as shown
-in the following example (the resulting file may contain garbage data at
-the end):
-
-@example
-lzip -cd rec00001file.lz > rec00001file
-@end example
-
-If the cause of file corruption is damaged media, the combination GNU
-ddrescue + lziprecover is the best option for recovering data from
-multiple damaged copies. @xref{ddrescue-example}, for an example.

-The format for running lziprecover is:
+Example 10: Create a multivolume compressed backup of a big database
+file with a volume size of 650MB, where each volume is a multimember
+file with a member size of 32MiB.
 
 @example
-lziprecover [@var{options}] [@var{files}]
+lzip -b 32MiB -S 650MB big_db
 @end example
 
-Lziprecover supports the following options:
-
-@table @samp
-@item -h
-@itemx --help
-Print an informative help message describing the options and exit.
-
-@item -V
-@itemx --version
-Print the version number of lziprecover on the standard output and exit.
-
-@item -f
-@itemx --force
-Force overwrite of output file.
-
-@item -m
-@itemx --merge
-Try to produce a correct file merging the good parts of two or more
-damaged copies. The copies must be single-member files. The merge will
-fail if the copies have too many damaged areas or if the same byte is
-damaged in all copies. If successful, a repaired copy is written to the
-file @samp{@var{file}_fixed.lz}.
-
-To give you an idea of its possibilities, when merging two copies each
-of them with one damaged area affecting 1 percent of the copy, the
-probability of obtaining a correct file is about 98 percent. With three
-such copies the probability rises to 99.97 percent. For large files with
-small errors, the probability approaches 100 percent even with only two
-copies.
-
-@item -o @var{file}
-@itemx --output=@var{file}
-Place the output into @samp{@var{file}} instead of into
-@samp{@var{file}_fixed.lz}.
-
-If splitting, the names of the files produced are in the form
-@samp{rec00001@var{file}}, etc.
-
-@item -q
-@itemx --quiet
-Quiet operation. Suppress all messages.
-
-@item -R
-@itemx --repair
-Try to repair a small error, affecting only one byte, in a single-member
-@var{file}. If successful, a repaired copy is written to the file
-@samp{@var{file}_fixed.lz}. @samp{@var{file}} is not modified at all.
-
-@item -s
-@itemx --split
-Search for members in @samp{@var{file}} and write each member in its own
-@samp{.lz} file. You can then use @samp{lzip -t} to test the integrity
-of the resulting files, decompress those which are undamaged, and try to
-repair or partially decompress those which are damaged.
-
-The names of the files produced are in the form
-@samp{rec00001@var{file}.lz}, @samp{rec00002@var{file}.lz}, etc, and are
-designed so that the use of wildcards in subsequent processing, for
-example, @w{@samp{lzip -cd rec*@var{file}.lz > recovered_data}},
-processes the files in the correct order.
-
-@item -v
-@itemx --verbose
-Verbose mode. Further -v's increase the verbosity level.
