xtracto writes: Is there an Open Source program or file available under Linux which can duplicate the feature available in the RAR file of adding a "redundancy record" to the file in order to allow recovery of the file if corrupted? I need to backup a vast amount of text data (log information for a scientific experiment) and currently I am doing it by compressing the data using tar and bzip2 format and then archive it to DVDs, but I would like to add some redundancy to the files (maybe a standalone program on top of the tar-bziped files). Is there anything like that on Linux?. Note that RAR is not a choice because of the closed file format (as this is scientific data which might be available for everyone in the future).
