Does all it promises. Very helpful!
The 1.5.2 beta1 I downloaded last year and have been using OK seems to have been pulled here and at mozbackup dot jasnapaka dot com. Since March of 2011, I think it's safe to say this project is dead. Considering the level of revisions and releases of newer OSs and clients in 2+ years, assume this app as unsafe. I will no longer risk using it So sad.
