Backup hardware showdown: Tape vs. Disk

چکیده
Executive Summary There’s a battle raging out there in the I.T. world about which backup solution is better – tape or disk? In this Whitepaper, we attempt to mediate the argument by presenting some simple facts about the real purpose of backups and the relative advantages of each medium in covering them... Indeed, once you’ve read this article, you may agree it might be time for a truce! Read on to find out how tape and disk can work hand-in-hand to complete the backup puzzle and create a more comprehensive solution than could be obtained by just using one method or the other. We also explain how using the right backup software can mitigate the disadvantage of both tape and disk, to give you better results.

Virtual Tape Libraries: The Best of Tape and Disk Backup
Tape backup has traditionally been the mainstay of enterprise data protection when long-term data protection is required. As disk technologies have improved and economies of scale have driven down prices, disk adoption rates have surged and it would appear disk is poised to eclipse tape as the dominant backup platform and relegate tape to a minor archival and disaster recovery role. Numerous su...
متن کاملPerformance of a Parallel Network Backup Manager
The advent of inexpensive multi-gigabyte tape drives has made possible the completely automated backup of many dozens of networked workstations to a single tape. One pioblem that arises with this scheme is that many computers cannot backup theiì disks óver the network at more than a f¡action of the tape's rated speed. Thus, running overnight backups sequentially can take well into the next day....
متن کاملData Backup and Recovery Options
One of the most fundamental elements of any disaster recovery plan is data backup and recovery. If an IT staff lacks the ability to recover lost data following an incident or disaster, redundant hardware or hot sites are of only limited value. Relatively few years ago, planning a backup strategy was reasonably straightforward for the small-office-home-office (SOHO) and small-tomedium-sized-busi...
متن کاملTLFS: High Performance Tape Library File System for Data Backup and Archive
A tape library is seldom considered as a viable place for constructing a file system for a sequential write/read device. Storage virtualization technology has become a buzzword in technology circles lately, in this paper we propose a tape library file system, called TLFS. The purpose of TLFS is to maintain a consistent view of mass storage so that the user can effectively manage it. Like disk f...
متن کاملA Backup Appliance Composed of High-Capacity Disk Drives
Disk drives are now available with capacity and price per capacity comparable to (and in some cases better than) nearline tape systems. Given disks' superior performance , density and maintainability characteristics, it seems likely that disks will soon overtake tapes as the backup medium of choice. In this paper, we outline the potential advantages of a backup system composed of high-capacity ...
