Abstract: An illustrative ISCSI server computing device provides user computing devices with “private writable snapshots” of a desired volume of data and/or further provides “private writable backup copies.” The ISCSI service is provided without invoking snapshot limits imposed by storage arrays and further without specialized backup software and pseudo-disk drivers installed on the user computing devices. A user can browse as well as edit personal versions of any number and/or versions of block-level backup copies—the “private writable backup copies.” Likewise, a user can browse and edit personal versions of any number of snapshots of one or more versions of one or more desired data volumes—the “private writable snapshots.” A user can have any number of co-existing private writable snapshots and private writable backup copies. Sparse files, extent-files, software snapshots, and/or media agents co-residing on the ISCSI server are used in the illustrative embodiments.
