I have tried to backup my 4Gig Scandisk USB drive using Toucan 1.2.0R3 with no success. I'm trying to back it up using the Incremental backup function of Toucan with maximum compression. It seems to start out OK. It writes to a BaseFile.7z for a few minutes and then the CPU load drop to about 3% when my pagefile hit about 1.06 Gig and Toucan seems to just hang there. I have tried this on two different systems. The first time I tried it I let the system run all night but it didn't do anything.
