COST SAVINGS OF DATA CENTRALIZATION INCREASED PRODUCTIVITY AND SERVICE LEVELS
Remove and retire backup equipment from remote
sites, saving in maintenance and upgrades
Remote and branch office systems run faster and with no
backup impact, supporting higher productivity levels for
business workers
Repurposes backup server systems to other
workloads
Efficient use of networks through combined effect of data
reduction from compression, encryption and deduplication
Eliminate the cost of tape cartridges from remote sites Ability to enforce common policies for data management across
all data, including data created in remote sites
Eliminate service contracts requiring tape collection
from each remote site
Ability to report on management of all data, including centralized
data, for executive oversight and validation
Eliminate or reduce human error in data management Higher levels of reliability for preservation of data for disaster
recovery and legal discovery purposes
Remove the burden of tape rotation and oversight of
backup/recovery from remote sites
Higher levels of data reliability and reduced cost of remote office
data protection
