Hot Spots: Data deduplication drama

The dedupe stage is getting crowded and confusing. Avoid trouble by knowing where to look for it. Data deduplication for secondary storage is prompting as much passion from vendors as it is confusion for some users. Why? Because dedupe is one of those influential, crucial technologies that comes along every few years. Deduplication promises to reduce the transfer and storage of redundant data, which optimizes network bandwidth and storage capacity. Storing data more efficiently on disk lets you retain data for longer periods or "recapture" data to protect more apps with disk-based backup, increasing the likelihood that data can be recovered rapidly. Transferring less data over the network also improves performance. Reducing the data transferred over a WAN connection may allow organizations to consolidate backup from remote locations or extend disaster recovery to data that wasn't previously protected. The bottom line is that data dedupe can save organizations time and money by enabling more data recovery from disk and reducing ...

  • Migrate data without mistakes

    by  Deni Connor

    Data migrations are a fact of life. In many cases, the migration ends up being a tedious process. Automated tools can help ease migration woes. Host-based migration software takes the load off the storage array and can easily bridge the gap when migrating data between heterogeneous storage systems. But array-based migration may be preferred for technology refreshes.

  • The big crunch: Capacity grows, budgets shrink

    The brief respite storage managers enjoyed from the ever-escalating need for more disk capacity appears to be over. Respondents to our 2008 Purchasing Intentions survey say they'll add an average of 47TB of new disk capacity this year. But they'll have to do it with smaller storage budgets. And while virtualization could help respondents use their storage more efficiently, it's still receiving a cool reception.
