Is Tape Backup Dead? We Expose the Common Myths and Rumors
Backup for the Rest of Us Is Tape Backup Dead? We Expose the Common Myths and Rumors. Trust NovaStor DataCenter for Fast, Reliable Data Security Introduction People have been proclaiming the death of magnetic tape for decades. There is a recurring tendency in some IT circles to declare backup to tape as obsolete or near death as ‘the cloud’ increasingly makes its way into the data centers of the world, as a backup destination. But even in these times of private cloud services, SAN snapshots, SSD’s, and cheap public cloud storage we shouldn't be too quick to lower the coffin. The rumors circulated by cloud service providers and disk vendors mighty have you believe that tape is slow, unreliable, or simply outdated. Perhaps you even have a personal experience, where a poorly implemented system was inherited or you got stuck using archaic backup software. Whatever the reasons, if you have preformed opinions, we ask that you temporarily suspend them as we tackle the most common misconceptions surrounding tape as a backup medium. Tape does not fit all situations and may not be the ultimate storage solution, but it may still have a few tricks up its sleeve when it comes to the long term retention and archival storage of your critical data. Today we tackle some of the most popular, and highly circulated myths about tape. Supported in the USA www.novastor.com 02 #1 Tape Is Dead Whoops, who said that? A global survey conducted by Kroll Ontrack in 2017 showed that while cloud storage use had doubled over the previous year, magnetic tape has also experienced an impressive boost in popularity. -

1. Background This Paper Is About a Method for Recovering Data from Floppy Disks That Are Failing Due to “Weak Bits”
A Method for Recovering Data From Failing Floppy Disks with a Practical Example Dr. Frederick B. Cohen, Ph.D. and Charles M. Preston Fred Cohen & Associates and California Sciences Institute Abstract: As floppy disks and other similar media age, they have a tendency to lose data because of the reduction in retention of electromagnetic fields over time associated with various environmental degradation factors. In attempting to read these disks, the coding techniques used to write them can be exploited along with the proposed fault mechanisms to demonstrate that repetitions of read attempts under proper conditions yield valid data subject to specific error modes. In many cases those errors can be partially or completely reversed by analysis of read results. A practical example involving a case of substantial legal value is used as an example of the application of these methods. Keywords: weak bits, floppy disks, digital forensics, coding, field density loss, the birthday problem, error inversion 1. Background This paper is about a method for recovering data from floppy disks that are failing due to “weak bits”. It describes a repetitive read technique that has successfully recovered data from failing floppy disks in forensic cases and describes analysis of the results of such repetitive reads in terms of yielding forensically sound data values. These techniques are not new or particularly unique; however, they are not widely published and analysis necessary to support their use in legal matters has not been found elsewhere. The particular matter used as an example in this analysis involved a floppy disk that was more than 15 years old and that contained the only copy of a binary assembled version of a software program that was subject to intellectual property claims of sufficient value to warrant recovery beyond the means normally used by commercial recovery firms. -
