FTK Case Removal

 

Case archiving

When the processing of a collection is complete, its case files, evidence files, and database in Forensic Toolkit need to be aggregated into a single directory and backed-up to storage. The FTK manual calls this process archiving. Before you begin archiving a case, first reference the FTK Archive Policy and speak to Digital Preservation staff to determine whether this collection will be archived according to the policy or if an exception will be made.
