Abstract: Cloud metadata is generated by a cloud block management system on a first storage array. The cloud metadata includes information identifying one or more cloud providers, one or more cloud repositories created on the cloud providers, and block objects stored in the cloud repositories. A metadata backup file containing a copy of the cloud metadata is generated, encrypted, and exported to an external computer. A second cloud block management system is created on a second storage array, and the metadata backup file containing the copy of the cloud metadata is decrypted and imported to the second cloud block management system. The cloud metadata from the metadata backup file is used to configure the second cloud block management system to access the one or more cloud providers, access the one or more cloud repositories created on the cloud providers, and to access the block objects stored in the cloud repositories.

Abstract: A beam-scanning optical design is described for achieving up to kHz frame-rate optical imaging on multiple simultaneous data acquisition channels. In one embodiment, two fast-scan resonant mirrors direct the optical beam on a circuitous trajectory through the field of view, with the trajectory repeat-time given by the least common multiplier of the mirror periods. Dicing the raw time-domain data into sub-trajectories combined with model-based image reconstruction (MBIR) 3D in-painting algorithms allows for effective frame-rates much higher than the repeat time of the Lissajous trajectory. Because sub-trajectory and full-trajectory imaging are different methods of analyzing the same data, both high-frame rate images with relatively low resolution and low frame rate images with high resolution are simultaneously acquired.
