gemino

Gemino is a file duplicator with advanced capabilities useful for copying forensics datasets and doing logical acquisitions.

Features

- Read Once: gemino reads the source data only once, even when copying to many sources

- On the fly hashing: gemino hashes the source data while copying

- "Multicasting": gemino uses multiple threads to optimize the writing of the copies to the target drives

- Verification: gemino verifies the written data to the destination devices.

- AFF4: Support for creation of AFF4 containers - Only one destination possible

Using gemino you can optimize the copy of large dataset to multiple drives for backup or distribution purposes. By reading the source data only once gemino does not suffer from source bottlenecks. Traditional copy by a script or via the OS GUI reads the source once for each destination; with a parallel copy to many disks this means parallel reads which slow the overall performance.

Reading the source data only once for the entire process (copy and hashing) allows gemino to increase drastically the copy performance, especially on slow source devices such as Network drives or HDDs.
