SAN FRANCISCO, California (AP) -- Google Inc. is offering a new tool that will automatically transfer information from one personal computer to another, but anyone wanting that convenience must authorize the Internet search leader to store the material for up to 30 days.

To enable the computer-to-computer search function, a user specifies what information should be indexed and then agrees to allow Google to transfer the material to its own storage system. Google plans to encrypt all data transferred from users' hard drives and restrict access to just a handful of its employees. The company says it won't peruse any of the transferred information.

Once another computer participating in a user's personal network is turned on, Google automatically transfers the information so it's available to be searched.
