Often on RAID systems an entire volume can be reconstructed if the Level 4 (dedicated parity drive) or Level 5 (block interleaved distributed parity) areas of the entire logical volume are available (Miller, 2007). Often forensic investigators will begin with these inherent advantages of the RAID technology, yet revert to virtualization techniques if these do not work (Leventhal, 2010). RAID is by nature a technology that can replicate list partitions and drives (Elerath, 2009) (Leventhal, 2010) (Miller, 2007).
Isolating which data has been lost and then defining a strategy for its recovery is critically important in the development of forensics strategies for reconstructing and recovering it (Miller, 2007). RAID techniques have proven to be exceptionally effective in reconstructing lost data, yet the use of virtualization techniques have augmented and accelerated greater forensic success rates of recovery (Teelink, Erbacher, 2006).
Conclusion
Initiating strategies for the recovery of...
Creating more effective approaches to recovering data needs to begin with an in-depth knowledge of RAID technologies followed with expertise in data visualization and recovery.

(RAID: searchstorage.techtarget.com) Necessity of an organization to implement RAID: RAID is important as sudden eventuality of data losses can be overcome by an organization so that information and data can be securely recovered. RAID is used to provide real-time, round the clock backup of the hard disk. The widely popular application for RAID is among the small enterprises. Experts constructing RAID systems for enterprise level businesses possess nearly several RAID levels
Examples are 10BaseT ethernet and 100VB AnyLAN networks. I would devise an intelligent hub that would have enhanced capacities for other features such as remote management capability. Switches are an addition o hubs and would also provide this prospective network with support capacities such as multiple bandwidths, bridge functionality, and router functionality. I will install a bridge that will filter data packets according to their various addresses. This will forward only
Fault Tolerant Analysis of RAID Redundant Array of Independent Disks (RAID) describes array configuration and applications for multiple inexpensive hard disks, providing fault tolerance (redundancy) and improved access rates (RAID concept). RAID provides a way to access multiple individual disks as if the array were one larger disk, spreading data access out over these multiple disks, reducing the risk of losing all data if one drive fails, and improving access time.
What questions should you ask the woman to assist you with your investigations? 1. Do you have a good relationship with your husband? Are you in talking terms as of this moment? 2. Is the laptop in your possession right now? If not, where is it? 3. What is the location of your husband as of this moment? Does he know where you are right now? 4. Before you saw what you saw last
Tony Chips Independent Company Website Tony's Chips independent company Website Scenario Tony Chips has recently bought a new independent company and the company is interested to move its old Website from external hosted solution to internal web hosting. Meanwhile, the company management is concerned about the redundancy of the Website and insists that the Website should have a back up in case the original Website goes down. More importantly, the site will be
The web server software provides log files, which constantly monitors the site and stores statistics such as the IP address of visitors and the pathnames of files that visitor's request. Every time the server serves a file, it records a 'hit' in the log file with that file's pathname. These sites, however, do not necessarily reflect the number of visitors to the site. It is simply a measure of how
