I have to agree with that. Really about the only issue people have
with v3 is that if you ever want to copy the entire archive tree to a
new system or to make an offsite copy it is a problem for
file-oriented copy methods to recreate the large number of hardlinks.
The changes in v4 may help some situations, but I wonder if the
attempt to locate existing matching content from different locations
might waste time where there are large numbers of tiny files.
If you do try v3, note that using the checksum-seed=32761 option will
speed up full runs but you won't see the difference until the 3rd
full. That is, the block checksums are cached on the 2nd full copy of
a file and then subsequently used so the server side does not have to
uncompress and recompute them.
