Archival formats have always been of interest to me, given the very practical need to store a large amount of backups across any number of storage mediums - documents, pictures, music, sometimes particularly good movies, even the occasional software or game installer. Right now, I've personally settled on using the 7z format: https://en.wikipedia.org/wiki/7z https://en.wikipedia.org/wiki/7z The decompression speeds feel good, the compression ratios also seem better than ZIP and somehow it still feels like a widely supported format, with the 7-Zip program in particular being nice to use: https://en.wikipedia.org/wiki/7-Zip https://en.wikipedia.org/wiki/7-Zip Of course, various archivers on *nix systems also seem to support it, so so far everything feels good. Though of course having the chance of an archive getting corrupt and no longer being properly able to decompress it and read all of those files, versus just using the filesystem and having something like that perhaps occur to a single file still sometimes bothers me. Then again, on a certain level, I guess nothing is permanent and at least it's possible to occasionally test the archives for any errors and look into restoring them from backups, should something like that ever occur. Might just have to automate those tests, though. Yet, for the most part, going with an exceedingly boring option like that seems like a good idea, though the space could definitely use more projects and new algorithms for even better compression ratios, so at the very least it's nice to see attempts to do so!
