S.C. Code Regs. § § 113-350
Real property records in the custody of the register are permanent records and must be preserved. The preservation of electronic real property records requires consistent and complex management in order to maintain authenticity and integrity. Electronic records are subject to the same threats of destruction as other mediums such as natural or human-made disasters. There are the added challenges of hardware and software obsolescence, media longevity and migration, infrastructure failures and accidental damage from improper handling. The durability of electronic records has not been proven to be as enduring as microfilm. In order to secure and preserve information created and stored electronically, permanent digital real property records shall be converted to microfilm.
