    Is there a way to use SnapRAID without the RAID?

    I want to use the SpookyHash algorithm to generate a hash digest for a Windows folder, and detect errors to the files (file integrity). I don't want the parity/redundancy features.

    Perhaps another project using SpookyHash?

    Thanks,
    Jake

    snakyjake,

    Until enough people request it you can easily add it yourself if you have coding experience as there are only a few lines of code needed ASFAIK (more will be required for configuration validation and testing code). You could create a special "no-raid" version and use the untouched copy for regular use.

    Check the forum for related topics.

    /X

    PS! I personally found it quite handy for backups and when copying folders between removable disks and servers to post validate the end result of the chain of file transfers. Also very useful for more volatile folders where redundency is not required but file integrity is.

    Hi snakyjake,

    The SnapRAID architecture is not the best one for a such tool. The problem of SnapRAID is that it always accesses all the disks in sync, to do parity operations, when instead a dedicated hashing program could work more efficiently operating on all the disks in parallel.

    Have you tried with md5deep/hashdeep http://md5deep.sourceforge.net/ ?

    Ciao,
    Andrea
