A Network Disaster Recovery Tips
To improve your chances for a full recovery from a crash, you must store the Exchange database files on a different hard disk from the transaction logs. The Exchange Performance Optimizer places the transaction logs on the fastest hard disk it can find and, if possible, on a different partition from the .edb databases. However, this utility can't see physical partitions. Therefore, if you have two physical disks (and no disk striping) and the faster disk is split into two partitions (e.g., C and D), Performance Optimizer might place the .edb files on one of those partitions and the transaction logs on the other partition of the same physical disk and not place any files or logs on the other drive (E). This placement is undesirable, because both the databases and transaction logs are on the same spindle. If the disk crashes, you can restore only from the last backup and you lose all transactions between the last backup and when the crash occurred.
You can place these two files on different physical disks by rerunning Performance Optimizer and manually changing the paths, as you see in Screen 5, page 4, to store .edb files on a different disk. Then, if that disk crashes, you need only run the restore tapes and restore up to the last transactions recorded before the failure.
Here are some other disk administration tips:
Install NT on a separate hard disk. If the Exchange Server hard disk crashes, you can concentrate on recovering just Exchange Server and not both NT and Exchange Server.
House the database files on a hardware RAID 5 unit. That way, failure of one disk won't shut the stores.
Ensure that ample free space is available when you run the defragmentation option of the EDBUTIL or the ESEUTIL program. You need at least twice as much disk space as the size of the database file you are defragmenting. The TEMPDFRG.EDB file will use this space to rebuild the original .edb. By default, the space allocated is on the same partition as the original .edb file, but you can reallocate the space with the /t switch.
Because Exchange Server 5.5 has a virtually unlimited store size, backups can be time-consuming. Have the fastest available hard disksusually SCSI hard disksand state-of-the-art tape units to keep I/O rates from bogging you down.
In Exchange Server 5.0, you can save time if you compact the Information Store before you use the EDBUTIL utility to back it up. However, Exchange 5.5 is more efficient in recovering deleted pages in the store and performs the function automatically. In either version, if you manually compact the PRIV.EDB or PUB.EDB files (using EDBUTIL in Exchange Server 5.0 or ESEUTIL in Exchange Server 5.5), you must shut down the Information Store service before you use the utility. If you shut down the Information Store service, you might want to shut down all the Exchange services and perform an offline backup of all partitions on the system. When the system is down, you can back up both NT and all Exchange Server databases at one time.
Format your tapes before backing up. Most folks assume that because the tapes they buy are formatted, the tapes are ready to go. However, even if your tape drive doesn't encounter any errors during the write process, it might not be able to read the tapes during the restore. By formatting your tapes with the tape device hardware you're using, you're more likely to have a successful restore.
Microsoft has provided its customers with information about recovering Exchange. Two excellent white papers are MS Exchange Disaster Recovery Part I and Part II in TechNet, February 1998. These papers are required reading for any backup operator.
Finally, don't forget that Microsoft has a GUI-based command scheduler that can perform offline backups automatically at specified times. Microsoft introduced this utility (WINAT) in the NT 3.51 resource kit. You need to create a batch file to shut down the Exchange Server services before the backup routine runs. Part I of the disaster recovery white paper describes this process in detail.

What we can a disaster recovery consultant do for you.
hat would you do if a storm flooded your data center? Or how would you respond if a power outage blacked out your servers? How would you recover your data and keep the business running after an unforeseen disaster? When disasters strike unprepared companies the consequences range from prolonged system downtime and the resulting revenue loss to the companies going out of business completely, yet many IT shops are not prepared to deal with such scenarios.
The key to surviving such an event is a business continuity strategy, a set of policies and procedures for reacting to and recovering from an IT-disabling disaster, and the main component of a business continuity strategy is a disaster recovery plan (DRP). In this article, DevX and Cole Emerson, President of Cole Emerson & Associates, Inc., a business-continuity consulting firm, and chairman of the board of DRI International, administrators of a global certification program for business continuity/disaster recovery planners, walk through the basics of creating an effective DRP.
