@Backup Corp, the San Diego, California-based online backup services company, demonstrated its SkyDesk virtual desktop technology at the Demo 99 conference in Palm Springs this week. SkyDesk enables users to access an exact mirror of their PC desktop, including data, applications and preferences, from multiple machines and locations. It can be run from any hardware with a web browser, including internet access devices and dumb terminals. SkyDesk uses data conversion and compression techniques, and incorporates Citrix Systems Inc’s ICA Independent Computing Architecture protocol. @Backup has installed Citrix’s MetaFrame software on its centralized servers. Citrix said last month that it had identified outsourced application services as a new source of income, particularly in the small business and consumer sectors, following a relaxation of licensing restrictions previously imposed by Microsoft on the use of NT in multi-user configurations (CI No 3,579). Available in the second quarter of the year, the SkyDesk services will be offered for an introductory period at $9.95 per month. @Backup was founded in 1995, taking employees from Intuit Inc, Stac Inc, Microsoft Corp and the San Diego Super Computer Center, and has gone through two rounds of funding. It maintains one petabyte of storage space and 50 T3 communications lines at its secure data center to run its online storage service aimed at PC users, and offers its subscribers protection against critical data loss due to disaster, theft, hardware failure and human error.
