关于格式
TAR.7Z is a compound archive format that combines the TAR container with 7-Zip's LZMA/LZMA2 compression. The TAR layer bundles multiple files into a single stream preserving Unix metadata (permissions, ownership, symlinks), while the outer 7Z compression applies LZMA or LZMA2 to the entire stream. This combination leverages LZMA's superior compression ratios — typically 30-70% better than gzip — making TAR.7Z one of the most space-efficient archive formats for Unix-style backups and software distribution. The solid-stream approach means compression can exploit redundancy across all archived files rather than compressing each file independently. One advantage is maximum compression density: the TAR.7Z combination often produces the smallest archives among common Unix archive+compression pairings. Broad tool support is another strength — tar and 7-Zip are available on all major platforms, and many modern tar implementations can create and extract TAR.7Z archives directly with the appropriate flag. The format is popular for distributing large source code trees and backup archives where minimizing transfer size justifies the additional compression time.
TAR.LZMA is a compound archive format combining TAR archiving with the LZMA (Lempel-Ziv-Markov chain Algorithm) compression method developed by Igor Pavlov for the 7-Zip project around 1998. The TAR layer concatenates files with Unix metadata into a single stream, and the LZMA algorithm compresses it using a sophisticated combination of LZ77 dictionary matching with large dictionaries (up to 4 GB), Markov chain-based probability modeling, and range coding. LZMA was the predecessor to the LZMA2 algorithm used in XZ and 7Z formats. Compression ratios significantly exceed gzip and are comparable to bzip2 while offering substantially faster decompression. One advantage is the high compression ratio with fast extraction — LZMA decompresses at speeds close to gzip while achieving compression densities near bzip2 or better, making it efficient for distribution archives that are compressed once and extracted many times. The format is supported by tar's --lzma flag and by 7-Zip across all platforms. While TAR.LZMA has been largely succeeded by TAR.XZ (which uses LZMA2 in a more robust container with integrity checks), existing TAR.LZMA archives remain encountered in software distributions and backup systems that adopted the format before XZ became widely available.
