Lziprecover

Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz) able to repair slightly damaged files, recover badly damaged files from two or more copies, extract data from damaged files, decompress files, and test integrity of files. Lziprecover is able to recover or decompress files produced by any of the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip, and pdlzip. It makes lzip files resistant to bit-flip, one of the most common forms of data corruption, and its recovery capabilities contribute to make of the lzip format one of the best options for long-term data archiving.

Release Notes: Copying of file dates, permissions, and ownership now behaves like "cp -p" (if the user ID or the group ID can't be duplicated, the file permission bits S_ISUID and S_ISGID are cleared). Some minor improvements have been made. "lziprecover.texinfo" has been renamed to "lziprecover.texi".

Release Notes: The new option "-i, --ignore-errors", which in conjunction with "-D" decompresses all the recoverable data in all members of a file without having to split it first, has been added. Option "-l, --list" now accepts more than one file. Decompression time has been reduced by 12%. "--split" now uses as few digits as possible in the names of the files produced, depending on the number of members in the input file. "--split" in verbose mode now shows the names of files being created. The targets "install-as-lzip" and "install-bin" have been added to the Makefile.
