  • No problem, let me just say that I haven’t tried it myself but I’ve watched a lot of videos of other people trying it and the worst results that I’ve seen have been the ones using a gel that they paint onto the plastic and then cover in plastic wrap. This tends to leave a streaky effect because the substance is not equally thick in every area and so it has more whitening effect where it’s thicker.

    The best results that I’ve seen have been the ones that have completely submerged the plastic in a liquid peroxide solution, or have suspended the plastic above the solution to immerse it in the vapors that evaporate off from the peroxide (pure oxygen). These methods give completely uniform coverage so they whiten the plastic equally in every place.

    It seems that you also need strong UV, and people that live nearer the equator have better success using the sun. But in the absence of good UV lighting, heat also seems to have some effect.

    Good luck!















  • You get incremental backups (snapshots) by using

    --link-dest=DIR         hardlink to files in DIR when unchanged
    

    To use this you pass in the previous snapshot location as DIR and use a new destination directory for the current snapshot. This creates hard links in the new snapshot to the files which were unchanged from the previous snapshot, so only the new files are transferred, and there is no duplication of data on disk (for whole-file matches).

    This does of course require that all of the snapshots exist in the same filesystem, since you cannot hard-link across filesystems.
