In survey after survey throughout 2010, storage managers listed data backup and recovery as their top priority. According to enterprise data storage managers responding to SearchStorage.com's Storage Priorities for 2010 survey, data backup (48%) was their No. 1 spending priority, followed by adding storage capacity (37%) and disaster recovery (36%).
The most popular

data backup
technology that caught storage and backup managers' eyes this year was data
deduplication (with 61% either deploying or evaluating it on top of the 23% current dedupe
users). The survey also indicated that after dedupe, four other technologies -- continuous data
protection (CDP), data archiving, backup for virtual servers and remote replication -- were also
important data backup technologies. Among already in-use data protection technologies, replication
was the highest (36%), with backup software for virtual servers close behind (32%).
To help you start the new year off on the right foot, and make sense of the latest backup technologies, we've gathered our top 10 data backup technology tips. Learn about the biggest backup trends of the year: data dedupe, cloud backup, virtual server backup, and more in this collection of tips.

LTO
tape technology continues to evolve with LTO-5
Data backup experts have been predicting tape's demise for several years. But the release of LTO-5
tape may have breathed new life into the technology. Listen to W. Curtis Preston's insights on the
future of LTO tape in this podcast. If you're using a older generation of tape, you may be
wondering whether or not you should upgrade to the latest version, what this version offers, and
whether or not LTO-5 is compatible with other versions of tape. Click here to get the answers to
these questions and listen to the podcast on LTO tape technology and LTO-5
tape.
TIP #5-------------------------------------------------------------------------------------------------
Archiving
storage vs. data backup storage
Data backups and data archives are frequently confused with each other. Many people don't know the
difference between the two enterprise data storage technologies, and often assume that if
necessary, they can use their data backup storage as data archive storage, which often is not a
good idea. In this podcast, learn about the differences between data backup and data archiving
products, and the dos and don'ts associated with each technology in this Q&A. Click here to
listen to the podcast on archiving
storage.

Virtual
server backup best practices guide
Server virtualization technology has had an enormous impact in data centers by advancing server
consolidation at a pace never seen before. Organizations of all sizes have slashed the number of
physical servers they need, allowing them to trim costs, cut complexity, and reduce power and space
requirements. But while they make a lot of IT chores easier, virtual servers make one key task a
lot harder: data backup and recovery. In this free guide, learn how to manage your virtual server
backup process, what tools are available to help you, and the pros and cons of each. Click here to
download the free guide on virtual
server backup.
TIP #7-------------------------------------------------------------------------------------------------
VMware
vSphere backup and recovery
When VMware Inc. released vSphere, the successor to VI3, many new enhancements to existing features
were included that are very beneficial to the backup and recovery of virtual machines. In this tip,
learn about what's new and what's changed, and how those features make for better backup and
recovery of virtual machines in vSphere. Click here to download the free guide on VMware
vSphere backup.
TIP #8-------------------------------------------------------------------------------------------------
Network-attached
storage (NAS) backup strategies
Whether justified or simply because the technology was misunderstood, backing up network-attached
storage devices were once considered a challenge for backup and storage administrators. This tip
reviews some of the most popular NAS backup strategies. Learn about traditional NAS backup, NDMP
backup, online data backup and more in this tip. Click here to read about the best strategies for
NAS
backup.
TIP #9-------------------------------------------------------------------------------------------------
Data
backup types explained: Full, incremental, differential and incremental-forever
backup
For quite some time, there have been three basic types of backups: full, incremental and
differential. More recently though, data backup software vendors have introduced some newer types
of backups that you might not be familiar with. Learn about synthetic full, incremental-forever
backup and other data
backup types in this tip.
TIP #10------------------------------------------------------------------------------------------------
Fixing
common problems with data deduplication systems
While data deduplication systems have helped make data backup and recovery much easier, they also
come with a number of challenges. The savvy storage or backup administrator will familiarize
themselves with these challenges and do whatever they can to work around them. Learn about
deduplication and encryption, the dedupe tax and other problems with deduplication
systems in this tip.
