7z archive format
7z format was developed and introduced by Igor Pavlov in 1999.
Used in 7z format, LZMA and LZMA2 are powerful compression algorithms and published as open-source (public domain), so they are used widely in the IT industry.
Advantages of 7z
7z is a relatively new archive format compared to the other old ones. So this format has these advanced features.
Disadvantages of 7z
To achieve even higher compression ratio, 7z uses various ways including header compression.
Because of those features, however, it is almost impossible to recover a compressed file when it is damaged even slightly.
Therefore, please be careful not to damage your important files when you backup them in 7z format.
You may find information on how to recover damaged 7z files in 7z website, but making a complete recovery is extremely difficult even for experts.
