Disaster recovery ensures that a business will always have a backup of its system in order
for them to continue its operations during, or after, a disaster. The most commonly used
server today is the MS Exchange and with its complicated system, a lot of things can go
wrong if there are no MS Exchange disaster recovery measures put in place. Without an
Exchange disaster recovery system, then the most an administrator can do is work with
what is left over in the system. If he is good enough, he will be able to restore the data
given some time.
If the Exchange database can still be mounted, then this is the first thing anyone should
do. If the computer cannot be booted up, then it might work if the disk is placed in
another machine and the database is worked on offline. Recovering the computer itself
should be dealt with separately. Once everything is in place, the Exchange disaster
recovery can be started.
There are two programs that will be used extensively in the Exchange disaster recovery.
These are the ESEUTIL and the ISINTEG which come with the Exchange program.
These two powerful programs will enable any system administrator to recover the most
recent backup of the system. But it should be worth noting that because they are so
powerful, these programs can also destroy everything the Exchange server has if no
proper precautions are made during the Exchange disaster recovery.
A good search on the internet will give anyone the basic command lines and procedures
on how to properly initiate an Exchange disaster recovery project. But even with these
powerful Exchange tools, a good backup of the system is still the best strategy to use.
