Offline use of Genozip

Can Genozip be used offline?

​​

Yes! While Genozip utilizes an Internet connection if one is available for various tasks such as checking for upgrades or sending telemetry (if requested), it does not require an Internet connection and can be used offline.​

​

 

Activating Genozip for offline use

​​

The only time Genozip actually needs an Internet connection is for activating the license – it needs to communicate with the license server.

​​

If the production environment is offline, the license can be activated on any other Internet-connected computer, including a Windows or Mac laptop. Instructions:

​

1. Install Genozip.

​​

2. Run genozip --activate and enter your license key.

​​

3. Copy the license file to the production machine. You wil find the license file here:

​

Linux / Mac: ~/.genozip_license.v71

​

Windows: $env:APPDATA/genozip/.genozip_license.v71 (PowerShell notation).

                  This is typically: C:\Users\USERNAME\AppData\Roaming\genozip\.genozip_license.v71 

​​

On the target (offline) machine, you can place the license in the home directory of the user that will be running genozip, or alternativey, you can place it anywhere else (and even rename it if you wish), and point to it with --licfile or $GENOZIP_LICENSE :

 

genozip --licfile mydir/.genozip_license.v71 mydata.bam

​

or:

​

export GENOZIP_LICENSE=mydir/.genozip_license.v71

genozip mydata.bam

​

​

Uncompressing offline

​

For uncompressing files with genounzip or accessing compressed data with genocat, activation is not required and Genozip does not inspect the license file, therefore these can be used offline without issues.
