The Long-Term Storage Manager is the DICOM server that automatically and transparently manages the repository of near-line and offline images, providing cost-effective storage management and archival and retrieval services. It copies images from online disks (Online Storage Management storage) to automated storage media, and restores the images back online as needed.
The Long-Term Storage Manager:
extends data protection by writing multiple copies to multiple removable media.
supports DICOM-3, supplying storage and retrieval services.
backs up and restores a nearly unlimited amount of data, with a lossless compression ratio of approximately 2:1.
can archive images from several Online Storage Manager devices simultaneously and can manage several storage devices (tape libraries).
uses a small online disk cache for holding studies that are to be stored on libraries compatible with and supported by NetBackup software, as well as recently fetched studies.
manages the library cartridges in the system by automatically exporting cartridges to the mail slot (for example, when the library is full).
imports requested cartridges from the mail slot.
The Long-Term Storage Manager can be installed either in a local configuration (on the same server on which the Online Storage Management is running) or in a remote configuration (on a separate server).
NOTE: For a WINDOWS OS, the Long-Term Storage Manager can only be installed on a separate server.
