Yes, of course there is a safe way. Use tar, restore, cpio or
whatever to recover the file from your backup. :-)

Once you rm the last directory entry that references the inode
(i.e. the link counter of the inode is zero), there is no file
anymore. There's only an orphaned inode. You can only copy
files, not inodes, so you first have to "fake" a new entry for
that inode to create a file. As far as I know, fsdb is the
only way to do this (and this is only a "hack", of course, it
is not supposed to be a clean way to recover files).
