It is slightly more difficult to replace individual chunks now since all the chunks are in MCR region files, so you have to unpack the current MCRs, unpack the back up MCRs, copy the chunks from the old into the new, pack it back into mcr.
It is much more trivial to just replace the whole region. regions are about 512x512 I think. Depending on how many regions the spawn area overlaps, you might be looking at replacing a 1024x1024 diameter, or might only be a 512x512, or 512x1024 etc...
Judging on the screenshots I saw, it is probably worth it, but then again that depends on how frequently the server does a hard backup.
