SweetCocoa has released a public beta of iMsafe 2, a backup tool for Mac OS X. The new version is rewritten from the ground up to take advantage of Mac OS X 10.3 (Panther). iMsafe can backup (even incrementally) to USB and FireWire hard drives, iPods, pen drives and to remote Macs on the network. The public beta runs only on Panther and expires May 1.
