Storage of sensitive data (tenants)

[Bienes Raices]

Like most people on here, I suppose, I now have old tenant applications with SS#s, birthdates, etc. Currently I am keeping them in a locked file cabinet (although my agreement with the credit service just says I have to keep them in a "secure place"). I was thinking of storing electronic versions on Crashplan or one of the the other backup services, and putting the originals in a safety deposit box.
I was wondering how other people handle this situation?
