A population of over one thousand IT sites involving ten major industries was surveyed and questioned on their Backup and Archive configurations, practices, objectives and plans.
This report provides statistics on practices, ranks issues and needs, indicates satisfaction ratings, and analyzes trends and plans.
The following parameters are analyzed by market revenue tier, and peculiarities pertaining to each of the major industries are highlighted
Servers and Operating System distribution Disk and Tape Utilization by data tier (primary data, backup, archive, mirroring) Disk and tape capacity- Versions and copies Libraries and Media used and planned Applications and Database Backup window and utilization of snapshot Handling of remote offices, desktop and laptops Disk to Disk Backup, and Acceptance of ATA drives Reliability Issues Criteria for accessing archived data HSM Products used, hardware and software Product and vendor selection criteria Satisfaction rating Major issues and problems Major technologies rating
Objectives of The Report
Backup and archiving have been constrained for many years by technology and cost. The convergence of factors such as the rapid increase of the volume of data, the threat of disasters, the cost of downtime and the advances of technologies are all fueling a major shift in the way IT managers look at data protection.
Several other factors influenced the changes as well, and they steered our survey questions to attempt to answer each parameter. We all agree on one point, things are bound to change. The unknown is how fast and in what direction. Assessing this was our major goal when we initiated this study and survey
While these were the main objectives, we collected and analyzed several other statistics and demographics, such as storage growth and distribution, storage budget and staffing, distribution of operating systems, servers, and software and library vendors.
Survey Methodology
To qualify for the survey, the respondent had to know storage, have at least half a terabyte of total disk capacity, and have responsibility for backup, archive and/or disaster protection
· We developed a questionnaire in collaboration with a number of industry executives. · We tested the questionnaire with ten IT managers, in one or several telephone interviews · We asked several thousands IT managers a limited set of questions to determine if they qualified for the survey. 1071 responded · Over 400 respondents qualified for the full survey. We selected 100 of them, with an attempt to have a relatively even distribution among the industries, as well as the disk capacity ranges · We sent a detailed questionnaire of over 200 questions to the selected respondents · We compiled and analyzed the results · We also included comments resulting from the many contacts we have throughout the year with IT managers, independently of this structured survey
