SteelEye LifeKeeper Disk to Disk Backup?


SteelEye LifeKeeper Disk to Disk Backup

The evolution to on-demand computing and the commoditization of disk-based storage is changing how organizations manage and protect their critical data assets.

Traditional tape-based backup provides a low-cost mechanism for data archival. But with the need to focus on availability and speed of recovery, tape-based backup is no longer an appropriate solution.

Disk backup, which provides the ability to replicate data between disks, introduces compelling new opportunities in terms of data protection, recovery and availability, as well as cost savings.

For many organizations, disk backup is now an essential component for enabling higher levels of business continuity and disaster recovery.

SteelEye LifeKeeper Disk to Disk Backup is a comprehensive, proven solution for providing real-time continuous server backup as well as data archival capabilities.

关键特性

  • 实时、连续的备份,磁盘对磁盘
  • 与磁带相比,访问备份数据在时间、成本和复杂度上仅是前者的极小部分
  • 在线数据访问,不需要从磁带恢复,消除了潜在的数据破坏可能
  • 连续、定期或调度的备份操作
  • 增量备份可减少备份数据量
  • 与现有磁带备份系统的集成
  • 与 Windows 备份工具的集成可节约更多成本
LifeKeeper Disk to Disk Backup is a foundation component of the SteelEye LifeKeeper family of data protection, high availability clustering and disaster recovery products that deliver "scalable availability" to organizations of all sizes.

实时、连续的备份
LifeKeeper Disk to Disk Backup enables continuous, real-time data backup. LifeKeeper Disk to Disk Backup overcomes the complexity of backup that relies solely on tape-based systems, and their significant cost in terms of performance, recoverability, data latency, and data corruption. Combining this real-time backup capability with the ability to do periodic snapshots provides both an element of high availability along with data recoverability.

零数据丢失
By backing up to disk, and taking advantage of the inherent data protection built in to disk drives, organizations immediately solve the most significant problem with tape-based backup - data loss caused by media corruption. Some industry sources estimate that between 15-30% of all restores fail because of a problem with which the data was originally written to tape, or data became corrupted because of the instability of the media.

With LifeKeeper Disk to Disk Backup production data changes are immediately and continuously replicated to a designated backup storage device. Should a system failure or disaster occur, organizations always have available the most current version of their data, and can eliminate data loss caused by having to recover from old archives.

即时数据访问 - 不需要等待恢复
With LifeKeeper Disk to Disk Backup, because data is always available on a hot disk, in the event of a system failure, the recovery process is virtually immediate. LifeKeeper Disk to Disk Backup replicates data to disk, without the requirement for encryption or compression. Subject to appropriate security controls, data can be accessed or restored immediately from the backup storage device.

灵活的保护
LifeKeeper Disk to Disk Backup offers flexibility in defining how and when data is backed up, with options for continuous, periodic and scheduled replication procedures. A useful feature is the ability to backup to daily online volumes, each of which can then be maintained for short-term data access requirements, and then be backed up offline to a tape system for long-term storage and data archiving.

与磁带备份集成而获得可移动的归档
LifeKeeper Disk to Disk Backup can work in conjunction with a wide range of industry-standard tape backup systems and devices to establish a variety of automated and scheduled backup procedures that eliminate the need to schedule daily backup sessions on production servers.

完全的数据安全性
LifeKeeper Disk to Disk Backup incorporates several critical features that ensure the highest levels of data protection and security:

  • In the event of a network failure, re-synchronizing data and disks is fast and dependable with LifeKeeper Disk to Disk Backup's intent-logging capability.

  • Because LifeKeeper Disk to Disk Backup works securely at the block level, below the file system, it provides organizations with direct control of what data is backed up and how data can be accessed.

  • Unlike file-level replication products, LifeKeeper Disk to Disk Backup replicates not only data files but also storage meta data files that contain critical information such as data access permissions that are vital to maintaining data security in the backup environment.

  • During operation, LifeKeeper Disk to Disk Backup maintains the highest levels of data protection by controlling access to the backup environment to prevent unauthorized or inadvertent update access, and to eliminate the potential for data corruption.

高性能 - 资源有效 - 节约成本
LifeKeeper Disk to Disk Backup replicates data at the block level, below the file system, and only backs up data changes, thereby minimizing the demand on systems and networks. Unlike file-based approaches to data replication, LifeKeeper Disk to Disk Backup is not dependent upon the file system to gain data access and does not incur the same levels of server resource utilization or latency that can cause critical out-of-sync conditions.

显著节约成本 - 与 Windows Backup 工具集成
Because LifeKeeper Disk to Disk Backup works below the file system, there are no issues with backing up "in use" files. Therefore, unlike tape backup products that do require the purchase of additional database and application agents in order to backup in use files, LifeKeeper delivers significant cost savings, particularly in large, multi-server environments.

Furthermore, for many organizations, LifeKeeper Disk to Disk Backup offers the potential to completely eliminate expensive vendor solutions for tape-based backup, and to instead rely upon the Backup utility that comes with the Windows operating system.

备份统一 - 透过广域网的集中备份
Many organizations are spread across campuses, cities, the country or around the world. With LifeKeeper Disk to Disk Backup, integrated with LifeKeeper Data Replication, an IT department can centralize backup operations into a single location.

可伸缩的可用性及灾难恢复
LifeKeeper Disk to Disk Backup is an integral component of the SteelEye LifeKeeper family of data protection, high availability clustering and disaster recovery products.

Integrating LifeKeeper Disk to Disk Backup with LifeKeeper High Availability Clustering delivers comprehensive, automated data recovery and application availability protection. Coupled with LifeKeeper Data Replication, organizations can establish a complete automated solution for disaster recovery protection over wide area networks.
