Data Archiving Options

Stand Alone System.

One or more copies of the original system (this may require duplicate hardware and software systems, plus the appropriate backups)  preserved in a static state. 

Pros

Maintenance costs are low if data is not needed on a regular basis (mainly storage).

Con

Cost to access and use data is high (original staff or documentation has be in place to be able to get to data). 

If original systems are destroyed or damaged, the data may not be recoverable or may be very expensive to recover.

This option might make sense when you are converting from a legacy system into a new one and want to hold onto the old system in case you need data from it.

Current System with Producion and Archive Databases

With this option, you run on a production system containing information you need for normal operating and reporting purposes and also can access your archived data from the same application.  As the operator selects the application, they can be optionally prompted to select the production, or the archive database/workspace.  The Archive workspace is normally set read only

This approach can be used to provide you with a Rolling 7 year history accessible from current program

This approach makes sense if you are running StreamV on an ongoing basis, want easily accessible archive data, and want to keep the size of the data in your production system manageable for performance, storage, backup or other reasons

With this method, some of the data in the primary system is moved to an archive database or workspace on an ongoing basis as it reaches a certain age (i.e. 7 years)

Other types of data are copied completely to the new system or may not be copied to the Archive system at all (depending on the type of data).

Pro

Archive Data is readily available.

Operators are familiar with both systems since they use the same application to access it

Con

Data in Archive System has to be kept current (may require restructure or adding index to old data).  System administrator may need full access to old data to allow making changes to it
