    DVDs are not at all a reliable media

    Hi,
    I have many data DVDs with me with all sorts of files. Today I opened an year old DVD and found that 2 files are not readable.

    So what is the most reliable media for storing important files ?

    Best I know is a brand new external mechanical hard drive that you only write to and read from - never deleting files/folders.

    Keep unplugged in a cool dry place except when you need it.

    May want to rethink the whole thing and go with online storage. Dropbox has served me well for years.

    You'd have to have a second online storage site, a backup of your backup, to be sure. What happened to Megaupload can happen to other online providers. Or they can get bought out and shut down like Geocities did.

    Home burned DVDs only last a few years because of the oxidation of the dyes. I've lost data that way in as little as a year and a half since recording. On that type of media, the clock starts ticking the minute the discs come off the factory line.

    The capacity of DVDs is kind of small by today's measures anyway so I'd second davetv's recommendation of an external mechanical drive. I'm not sure how long those are supposed to last in storage, but they are relatively cheap and if you get two different brands/models they are unlikely to fail at the same time.

    Edit: Here's a better diagram of the layers involved in the DVD: http://www.clir.org/pubs/reports/pub121/sec3.html

    Why are you recommending a mechanical drive and not a solid state drive like a usb pen drive ?

    Are you using the free 2 gb space provided by dropbox ? or are you paying for extra storage ? Coz to backup large files like video files I need good amount of space.

    I have 8gig of storage for free. You get your friends to sign up and you will get extra storage space for free. If you want to back up video, thats a different story as you need a good amount of storage. Are you using dvd to backup video? Must have a good size collection.

    I will try n find someone who is willing to sign up. Yes I use DVDs to backup my videos. There must be 40-50 of them with me.

    But now I am worried I will loose all that data eventually.
