Is anyone aware of any regulatory guidance or standards regarding data retention for CMMS systems? We are specifically looking to archive old data (asset records, work orders, etc) from our system to improve performance. We have also added computing power to the server/servers. Our CMMS vendor made a reccomendation to discard or archive old data, but could not cite any standards, or industry best practice literature to support a specific approach. My thought would be to obviously keep all active asset and WO records, but then look to archive offline or in an "archived" sql db instance all assets that have been retired more than X years and their corresponding WO histories. The question is what is X?
