9.2.6. Storing data relating to the minimum dataset system After entering data in the MDS how long should I store my hardcopy and/or electronic files?

There is no set time limit; however, it is recommended that you archive this data and keep it secure for at least two years. As with all electronic data (including MDS) there is a risk of corruption due to a system bug or human error. The MDS stores the original upload files and the imported data, however it is always good to keep the original data as a backup to either check details against or re-enter, if needed.
