Cloud services cut both ways in terms of security: you get off-site backup and disaster recovery, but you entrust your secrets to somebody else's hands. Doing the latter increases your exposure to government surveillance and the potential for deliberate or inadvertent breaches of your confidential files.

I favor pocket-sized hard drives that travel between home and office, syncing with computers on both ends.

Well-secured files don't do you much good if you lose them in a fire or hard drive crash.
