    Lightbulb Archiving & Data Integrity

    Hi All-

    I just found a very neat tool: par2 . Given a large file or set of files, it will construct a set of verification files that the tool can use at a later date to verify the integrity of the file(s) at a later date, and if any of the data was corrupted it will repair the data (up to a certain user-settable redundancy level). It does this using the fancy Reed-Solomon encoding scheme.

    I figured I'd use that in any long-term archival process.

    However I'm wondering if the new BRTFS filesystem would do that sort of thing automatically. I'd probably like to use both.

    Yeah, par2 is pretty great. Especially when not all the files from a Usenet download are available, you can use the par files to reconstruct the missing files.
