Introduction

The Next Generation Archive System (NGAS) is a very feature rich, archive handling and management system. In its core it is a HTTP based object storage system. It can be deployed on single small servers, or in globally distributed clusters.

Some of its main features are:

• Basic archiving and retrieval of data
• Data checking via various checksum methods
• Server-side data compression and filtering
• Automatic mirroring of data
• Clustering and swarming
• Disk tracking and offline data transfer
• High customisation via user-provided plug-ins

NGAS is written in Python (3.5+, support for 2.7 will be removed soon), making it highly portable. There are a few dependencies on C libraries, which may restrict the ability to install it on some of the more exotic platforms.
