Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for providing a software update. A system is configured to receive, from an update server, an update patch for a computer program installed on a memory of a first computing machine, execute the update patch on a first computing machine to update the computer program, receive a request for the updated computer program from a second computing machine, and transmit the updated computer program installed on the memory of the first computing machine to the second computing machine without transmitting the update patch.

Abstract: A redundant image storage system for archiving an image data file within at least two picture archiving and communication systems (PACS), said system including coupled source and destination PACS networks. The source PACS network stores and transmits the image data file. The destination PACS is associated with a Remote Archive Locations record and a Source PACS Archived flag. The destination PACS network receives the image data file from the source PACS network, stores the image data file and determines whether the image data file should be stored back on the source PACS network and if not then sets the value of the Source PACS Archived flag to be true. The destination PACS network only sends the image data file to the source PACS network for storage if the Source PACS Archived flag is false.
