I am currently burning some files on DVD for a friend who wants to keep this DVD for "long-term" storage.
I am going to employ dvdisaster to add a layer of protection against data loss.
In order to be able to maintain original file names and original file creation dates, I want to put the files into an archive.
Considering that DVDs don't last forever, and that even minor scratches on DVDs can lead to massive data loss, I was asking myself which archive file format in this context might provide the highest level of error-tolerance.
I'd guess one can say that
- Disk ARchive (.dar, cf. http://dar.linux.free.fr/),
- tar with gzip (.tar.gz = .tgz)
But which of those four would be the least vulnerable – what do you think?
Greetings, and thanks in advance for your assessment, Joe
