How To Get Data Solution For The Raid Recovery And Server Recovery
Depending on your needs for availability, you may want to have server farms in your area to which your system can switch
. If you do not have redundant batteries, it is recommended that you store recent backups offsite so you can quickly acquire equipment, rebuild and restore your server farm in case of fire, flood or other catastrophic event. A backup at the server farm is often appropriate for this purpose.
You might need to avail
Server Recovery Service in the following situations:
Server displays error message while bootup
Inaccessible hard drive volumes or partitions
Corrupt system files or file system
Virus infection
Hard drive component failuree
Hard drive corruptio
Media surface damage
Natural disasters like flood, fire and earthquake
This article describes some key aspects of disaster recovery in Exchange 2000. Whether or not familiar with backup and restore in Exchange 5.5, see the following sources of information to improve your knowledge and skills in disaster recovery:
Active Directory and Exchange 2000 Server
Servers that are running earlier versions of Microsoft Exchange have their own databases directory are replicated to other servers on the same Exchange site. In contrast, the Exchange 2000 servers use the directory service Windows 2000 Active Directory. Active Directory replicates information about mailboxes and configure Exchange in a Windows 2000 forest.
Connect Exchange server 2000 domain controllers running Windows 2000 Active Directory. Exchange 2000 can read and write data in Active Directory directory if necessary.
Note For more information about domain controllers on Windows 2000 and Active Directory, see the documentation for Windows 2000.
Technology Exchange database
A good knowledge of the core technology underlying data will help you understand the process of backup and recovery. Among the significant improvements in Exchange 2000, it should include the concept of multiple storage groups, banks of mailboxes and public folder stores multiple in each storage group. A database contains data from a bank of mailboxes or public folder store. You can save and restore individually or collectively, the databases of a storage group. A single set of log files contain entries for all databases in the storage group.
What is RAID and
RAID Recovery ?
Since its inception, the main peculiarity of the RAID architecture is its ability to combine many storage devices cheap and a mainstream technology in a single matrix, so that this group offers capacity, reliability and / or improved performance, for a cost far below a single storage device equivalent operating technologies. The RAID architecture is opposed to architecture SLED (Single Large Expensive Disk), which is based on the use of a single hard drive capacity, and therefore a high price because it must not only able to store much information, but it must also be of excellent quality to ensure maximum integrity.
Typical Causes of RAID Array Failure:
Multiple hard drive failure
Loss of server registry
Unintentional reconfiguration
Lost or reformatted partitions
Configuration corruption
Controller failure
Accidental array re-initialization
Component replacement
Indeed, in an architecture-type SLED, good data retention is dependent on any hard drive failure. When an outage occurs, not only the system is unworkable time replacement of defective hardware, but the only way to recover data is to undertake a restoration of the last backup, which can take several hours during which the system is still unusable.
If this downtime is acceptable for a particular computer, however it is prohibitive for the computer system of an enterprise for which such a failure can have significant impact on its financial condition. The use of RAID architecture, at least in most of its functional levels, allows precisely to respond to these needs for not only the failure of one disk in the cluster does not interfere with the operations of other discs This allows the system to continue functioning, but also, once the failed drive exchanged, its content is reconstructed from other records during the normal operation of the system. Thus, the company's business continues uninterrupted and transparent throughout the duration of the incident.
RAID, according to its functional levels, it gives response times identical to those records if they were used individually, offering special rates supported, even when using hard drives cheap and average performance, while ensuring a much more reliable (except for RAID 0 which reduces by 2). In such situations, the RAID architectures prove therefore ideal both in terms of their performance as their reliability. In all cases, the RAID is completely transparent to the user, regardless of the number of physical drives used to build the RAID, will never see a single large logical volume, to which he accedes to quite usual .
