None of the plugins performs a copy-on-write style full backup of $JENKINS_HOME on the master (I am assuming workspaces are not included or stored somewhere else). Why copy-on-write: because I want close to zero down time in my Jenkins master when performing the backup. I also see no evidence of any of the backup plugins applying a proper quiesce strategy.

The problem is that they are using stupid mechanisms to copy the filesystem that cannot correctly copy a symlink. This breaks the LastSuccessfulBuild and LastUnsuccessfulBuild and LastFailedBuild symlinks, causing lots of secondary issues. Doing my own using cpio or rsync in a cronjob only messes up copying very large files that exceed the archive limits (4GB for cpio for instance).
