1. A method for securing a data set, the method steps implemented by a programmed computer system, the method steps comprising: encrypting, using a hardware processor, the data set based on an encryption key to produce an encrypted data set; creating hash information based on a hash operation using the data set; generating data splitting information, wherein the data splitting information is usable to determine into which of a plurality of shares of data a unit of data of the encrypted data set will be placed; separating the encrypted data set into the plurality of shares based on the data splitting information, wherein each share contains one or more, but not all, of the units of data of the encrypted data set, and wherein at least two of the plurality of shares contain different amounts of the encrypted data set; including in the plurality of shares data indicative of the encryption key and the hash information; and causing the plurality of shares to be stored in separate storage locations; wherein the data set is restorable by accessing less than all, but at least a threshold number of, the plurality of shares.
