    Default Testing back up files

    I do regular back ups of my files and am wondering how best to check they are uncorrupted, other than opening each one in turn?

    Are there programs that do this on Linux and if so which ones are good?

    Ta.

    What's wrong with diff from the command line/shell script?

    diff <directory1> <directory2>

    The only way to be sure a backup works is to restore from it.

    Probably nothing, apart from my not knowing about it

    I'll give it a try

    couldn't speak for linux but I've had some weirdys with microsoft image files.

    I have 3 backups of data scattered about & 2 system images-one current & the other one before that. I have to say I'm having doubts about windows created ones. I tend to use samsung/ seagate drives so I use the free Discwizard software. It actually only needs one samsung/seagate/maxtor drive attached-it DGAS about who made any others. That is Acronis TrueImage underneath, which is pretty blardy good. I dunno about linux though.

    What if you're doing incremental or differential backups?
    What if the backups are encrypted?

    I got the impression dear old Cheb is copying files from one location to another.

    Cheb - are you or are you using a programme to back stuff up?

    Ditto. Discwizard takes a lot of pain out of backups. Acronis engine and it just works. Great for cloning systems too!

    Either click and drag, or cut and paste from one drive to another. USB sticks, USD HDDs, HDDs and SSDs all feature
