I'd assume not in a bank because any bank can fail at any moment and they are only insured by an instutition as flaky at the United States Treasury department. Governments collapse all the time just ask the Soviet Union. Right?
If you bank fails, you will be made whole with money from the FDIC. Money is fungible. Any money will do.
Data is not similarly fungible. There's no IT FDIC to replace your lost data with other data that's identical.
