While this is not exactly on-topic (improvements to rsync) I have
always just done this sort of thing on large rsyncs. In this case
large == 4.1TB.
# mirror the raid(s)
for i in `ls -1 $src`
rsync -av --stats --delete-after \
$src/$i $dest > $dest/logs/export-raid01-$i-$date.log
For some reason this always seems to complete faster than just
rsyncing the entire tree in one bash. I also seem to remember a
wrapper aound rsync that does this called gigsync but it is a whole
lot cleverer about how it chops things up. In my case I just happen
to know that there is a fairly even split of data in the first level
PS: Yes I know I _should_ use find instead of ls -1, call me slack.
