I don't know the details of the dump program you are referring to, but those I have checked all have the limitation that the restore is run purely in user space, meaning that they will have the same problem with restoring the hardlinks. There is simply no syscall to create a hardlink by inode number (and for good reasons - you can't check visibility of an inode, only of a path, and please don't argue "root permission" ;-), so you still need to keep track of names for files with more than one hardlink. While it is totally possible for restore programs to be smart (i.e. specialized) enough to get around this limitation, it is equally possible that this was not recognized as a problem - hundreds of thousands of files with more than one link will "just work" on any reasonable hardware without special handling, and this is probably more by several orders of magnitude than an average file system will contain. So, my question is basically, have you tried restoring a dump, and have you got more than "works for me" to support that it will scale?
