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. If an exception is to be made, you will be provided with a README.txt template to include in the case.

Archiving a case

  • Right-click on the completed collection from the FTK main menu. Point to Backup and click Archive and detach. Click OK in the popup window. This will perform an SQL dump of the collection database into its case folder (archive) and remove all collection related data from the FTK database (detach). The directory will be named ‘DB f-0’.

  • Open 7Zip manager from the desktop. Navigate to the evidence directory on the FRED. Highlight the collection you are working on and click the plus button to bring up the compression dialog.

  • Add “-evidence” to the file name in the Archive field, then click start to Zip the evidence directory. Use the following settings.
    Archive format: zip
    Compression level: Normal
    Compression method: Deflate
    Dictionary size: 32 KB
    Word size: 32
    Number of CPU threads: 12

  • Cut and paste the evidence zip into the case directory. The contents of the case directory should resemble:

  • Create a zip of the case folder using 7Zip manager. Name the file [collId]

  • Open the archived directory and find the appropriate folder for the current year and quarter. The folder naming convention is yearQ# (e.g. 2016Q1). Copy and paste the zipped case into this folder.
Q1 January - March
Q2 April - June
Q3 July - September
Q4 October - December

If the case being archived has an exception to the retention policy, open the archived directory and find the folder labeled archived\FTK\version (e.g. archived\FTK\5.6) and cut and paste the zipped case here.

  • Delete the following:

    • The collection directory in Cases

    • The collection directory in Evidence

    • The collection directories in Backups
