Enhanced Tennessee Roadway Information Management System (ETRIMS)
Hardware Description
The data for ETRIMS is stored in TDOT's Database running on physical servers.
Software Description
The servers run the current version for virus protection. Avamar is the Enterprise backup solution.
System Location
Strategic Technology Solutions (STS) South Data Center (92 Weakley Lane, Smyrna, TN 37167) hosts the servers that are utilized for the storage of the TDOT data managed by STS.
Backup Procedures
Strategic Technology Solutions (STS) will conduct backup procedures. These procedures consist of daily backups that are kept on the Data Domain for 31 days. These are then moved off to ECS and maintained as long term storage.
Disaster Recovery
Strategic Technology Solutions (STS) conducts disaster recovery. This procedure is a prioritized process of enabling critical and essential applications first and then continuing through the priority list to less significant applications. Disaster Recovery begins with the utilization of the STS’s North Data Center for both operations and data. If both STS’s South Data Center and STS’s North Data Center are out of operation, new operations will begin by acquiring appropriate hardware and software from a third party supplier and restoring data from backups.
