PreRoll Post streamlines the archiving process and most importantly verifies the files. In my opinion there is no point to archiving without verification! Without knowing the files have been written correctly and checked, means, if something goes wrong, the archive is useless. I have seen at least one instance of a file failing verification. As an experiment I tried to copy the file to drive and the process failed. That’s why I use PreRoll Post – to copy files to LTO tape and to then verify that these files are written correctly.
