Too Perfect a Mirror
The number of commenters that think the KDE sysadmins were stupid enough to not know that "raid isn't a backup strategy" is depressing. You either didn't read the article or you haven't understood it.Git repositories contain redundant information to perform consistency checks. If a bit flips in one of your repos, git fsck will immediately catch it. The KDE sysadmins thought these consistency checks were triggered when keeping a repository clone in sync and thus any FS level corruption would be caught at the first subsequent attempt to sync.If you think "Gee, if I know this, surely they do?!" then perhaps the answer is: "They probably do and this issue is more subtle than you initially thought. Reread carefully before implying how dumb others were."
