BUR Storage definition
BUR Storage means a storage environment consisting of backup-to-disk, backup-to-tape, or a backup environment consisting of a virtual library system (VLS) which contains both disk and tape. Disk-based backup solutions are much faster than tape-based backup systems because the disk media does not have the inherent mechanical inefficiencies of tape where the tape has to fast-forward or rewind in order to locate the appropriate place on tape to read or write data. Disk-based solutions can reposition the disk head directly to the location on disk where the data resides, and then transfer data at a much greater rate than most tape solutions.
