RAID 1 数据恢复

工作原理

RAID 1 數據儲存

标准 RAID(独立磁盘冗余阵列)级别是由基本配置组成的,用于通过条带化、镜像或奇偶校验技术,将多个通用计算机硬盘驱动器(HDD)组合成大容量且可靠的数据存储系统。

RAID 1 offers a bit more data security than RAID 0 because it utilizes mirroring (or replicating) data from one disk to another. This at least provides this RAID configuration a measure of redundancy, assuming the failed drive is replaced immediately.

典型的 RAID 1 配置是在两个磁盘之间创建一组数据的精确副本(即镜像)。这种配置不使用奇偶校验、条带化或跨多个磁盘扩展空间,因为数据会在阵列中的所有磁盘上进行镜像。这种布局适用于当读取性能或可靠性比写入性能或最终的数据存储容量更为重要的场景。

RAID 1 实际上是“容错”的,因为数据在阵列中的另一块磁盘上有完整的镜像副本。如果一块磁盘发生故障,数据不会完全丢失——前提是故障磁盘在正常磁盘出现故障之前被更换。

Data Loss

RAID 1 故障

由于 RAID 1 配置本质上拥有两个完全相同的驱动器,它可以在出现硬件故障或坏道/读取错误(硬错误)时提供一定程度的保护和恢复能力。但它无法防止因灾难性事件(如火灾、水灾)、多个磁盘同时故障、操作失误、软件故障或恶意软件感染导致的数据丢失。对于重要数据来说,RAID 不能替代备份方案。

救援

RAID 1 数据恢复

若 RAID 1 發生故障導致資料遺失,您可以嘗試使用 RAID 1 資料救援軟體。然而,即使是最好的 RAID 1 救援工具也無法修復大多數導致資料遺失的根本問題。在嚴重的情況下,這類軟體可能無濟於事。自行操作的工具甚至可能使情況惡化,讓資料救援變得幾乎不可能,即便是最專業的 RAID 0 救援公司也無能為力。

我們的建議很簡單:如果您遇到 RAID 1 故障導致可能的資料遺失,請立即聯繫 DriveSavers。RAID 1 資料救援正是我們的專業!我們擁有超過 40 年的業界領導經驗與卓越的成功率,是資料救援領域的專家。

RAID 1 資料救援專家

Our certified RAID 1 data recovery engineers have the in-depth knowledge and technical expertise that comes from over 40 years of data recovery experience, allowing us to achieve the highest success rate in the industry. DriveSavers Enterprise Systems Group specializes in recovering data from all operating systems and all types of high-capacity devices including redundant arrays of independent disks (RAID), network attached storage (NAS), storage area networks (SAN) and multi-disk servers. We routinely rescue lost databases, ERP accounting systems, mail servers and other mission-critical data for organizations of all sizes.

与 RAID 1 制造商
紧密合作

由於 RAID 裝置根據製造商採用不同的組件與配置,因此我們的資料救援工程師必須深刻了解各種專有的中繼資料結構與硬體設計,這一點至關重要。

Technical alliances with RAID controller manufacturers have enabled our engineers to develop proprietary techniques, tools and technologies that aid in data recovery from RAID devices based on solid-state drives (SSDs), hard disk drives (HDDs) and more complex hybrid and tiered storage environments. All major Raid 1 manufacturers authorize our data recovery services so working with DriveSavers will not void your original warranty.
