LAN-free backup in different flavours: LAN-free backup A LAN-free backup is a backup of server data to a shared, central storage device without sending the data over the local area network (LAN). It is usually achieved by using a storage area network (SAN). Note that trivial backup to a dedicated, unshared storage device (such as local tape drive) does not meet the definition. The goal of LAN-free backup is to reduce the load on LAN and reduce the time it takes to complete the backup. It offers an alternative way of backup than a simple data copy to network-attached storage (NAS) over
ACM Transactions on Multimedia Computing, Communications, and Applications ACM Transactions on Multimedia Computing, Communications, and Applications ACM Transactions on Multimedia Computing, Communications, and Applications (TOMM) is a quarterly scientific journal that aims to disseminate the latest findings of note in the field of multimedia computing. It is published by the Association for Computing Machinery. In May 2014 the acronym has changed from TOMMCAP to TOMM. The journal is described as follows on the ACM Digital Library website: "... focuses on multimedia computing (I/O devices, OS, storage systems, streaming media middleware, continuous media representations, media coding, media processing, etc.), multimedia communications (real-time protocols, end-to-end streaming media, resource allocation, multicast
