an other idea is to make a "snapshot" of leveldb and utxodump takes it instead of the original db which is in use of bitcoind (http://www.linux-magazin.de/ausgaben/2004/09/unwetterzentrale/3/)

"A good approach would be to close the DB, then hard link all the sst files (cp -l) and copy all the non-sst files. This way you only actually copy a small amount of data (size of your log, 4MB by default). Then you can open the DB again.

You do have to block while this happens, but hopefully it should be quick."
