Lessening filers' backup load

Do you have NAS devices that are struggling to balance file serving and backup? Atto Technology says its new $6,995 appliance will offload a significant portion of the Network Data Management Protocol (NDMP) processing that NAS devices rely on to do backup. "There are three components to an NDMP process: the file server, the backup server and the tape server," says Don Ko, product manager at Atto. "We offload the tape server," he says, which would otherwise run on the filer. How much of a load the Atto FastStream 4600 NDMP appliance will take on depends on the volume of data you need to back up. Atto FastStream 4600 NDMP also acts as an Ethernet-to-SCSI gateway, making it possible to put legacy SCSI-based tape systems on the network and then share them across multiple NAS devices. Putting SCSI tape devices behind an Ethernet gateway avoids SCSI's 10-meter cable length limit, says Ko, and could conceivably be used to do tape vaulting to a remote location. --Alex Barrett (AB)

Features in this issue

  • Tricky backup for SharePoint

  • CDP: Look before you leap

    Some pundits have postulated that continuous data protection (CDP) will replace backup. But is that just new technology hyperbole or is CDP a must-have technology?

  • Backup-to-disk performance tuning

    Disk-based backup can lower costs, reduce complexity and add scalability. But to achieve top performance, you'll need to do lots of benchmarking and watch for poorly configured production storage.

Columns in this issue

  • Backup best practices are always evolving

    Some new advances in backup, such as virtual tape libraries, represent evolutionary enhancements to the traditional backup process, while others like continuous data protection and single-instance storage are potentially far more transformational.
