Hi Peter, > At how old should I be 'refreshing' or duplicating my DVD backups?
Format shift quite often, I would think. That said, I've some 5ΒΌ" floppies to access one day. Rob Pike recently wrote about the topic and the value of real photos tucked away in a shoebox for your descendants. http://commandcenter.blogspot.co.uk/2014/08/prints.html If archiving data, you could consider generating error correction codes yourself, quite separate from whatever the media might be using under the covers. par2(1) was one program to do that. http://en.wikipedia.org/wiki/Parchive Then again, Olly did PaperBack, a program for printing data onto paper for later retrieval by scanning, again using ECC for coping with the odd coffee stain. I fear data density may not have kept pace with data growth, though with another data deduplication... http://ollydbg.de/Paperbak/ Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday, 2014-09-02 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue
