Enterprise-ready VTLs

Most virtual tape libraries will accelerate backups, but there are key differences among them when it comes to scaling, interoperability and management. For a growing number of organizations, a virtual tape library (VTL) provides a cost-effective addition to their disk-based backup. By storing data to disk rather than tape, the VTL speeds data backup and retrieval without requiring users to change their existing backup processes. This is because, to the backup server and backup application, the VTL looks like a traditional tape library. Benefits include squeezing ever-larger data sets into tight backup windows, retrieving data quickly when required for legal or regulatory reasons, and reducing the operational and reliability risks related to tape. However, not all VTLs are created equal. The larger and more complex the storage environment, the more attention users should pay to how the VTL provides scalability, performance, manageability and deduplication which, by storing only unique bits of data, can reduce disk capacity and ...

  • Get your iSCSI game on: Best Practices

    by  Ashish Nadkarni

    iSCSI is a mature protocol for accessing storage and a solid alternative to Fibre Channel. Technologies such as blade servers and server virtualization benefit from iSCSI as it lets you minimize the number of connections required. And because everything is IP-based, there's no more need to waste slots for host bus adapters, which simplifies your configuration.

  • The big pipe: Editorial

  • Backup gets a boost: Hot Spots

    by  Lauren Whitehouse

    Snapshots, continuous data protection and deduplication are making their way into traditional backup products. By capturing, transferring and storing less data in the backup process, organizations can back up more data to disk--retaining data on disk for longer periods of time or enabling disk-to-disk backup for more sets of data than before.
