|
|
I've recently change around my backup system, and as such I'm looking at moving files to a dir, then try to minimize the size of the files by tar/lzmaing the file(s).
Does anyone know what could happen, using the defaults, when mixing lzma and bzip2? _________________ The day Microsoft makes a product that doesn't suck, is the day they make a vacuum cleaner. |

If I've understood correctly, you want to compress bzip2 file with lzma or other way around. This shouldn't cause any problems, but generally when using two high-level compression algorithms there is no real gain in terms of file sizes. |

Well, I realize that there wouldn't be a gain, but compressing it, taring it into a file, then zipping the file is what I was concerned about.
I know that compressing a text file w/ lzma, then with bzip, it actually ends up larger, but I just wanted to make sure this wouldn't screw something up/ _________________ The day Microsoft makes a product that doesn't suck, is the day they make a vacuum cleaner. |

Each compression routine takes care of integrity of its content, so you should be safe. |
