4 h to estimate !

Even 10 hours!  + 8 hours to dump the filesystem.

here is the result of amplot -l -e -p amdump.1

You clearly have an estimate problem.
Using gnutar with a filesystem with zillion small files?

But why would the estimate take even longer than the real dump?
Maybe you have some unresponsive nfs mount from some dead host?

You're the perfect test candidate for the faster, statistics
based estimate, that is currently in 2.4.5beta.

Or switch to dump, if that is possible on the filesystem;
