Methods of Database Recovery

Have you dropped your laptop? Is it overheating? Is your Database having issues? Do you Suspect the hard drive has Crashed?

Any information belonging to an organization is usually stored in form of a database. In case information is lost in the database, it would have major negative effects on the organization. Data recovery analysts have found out that it can cost you upto $8000 per MB to recreate client information. This is because of various costs that may be incurred such as overtime pay of re-entry, transportation costs for the client and also communication costs.

To help reduce on these costs, it would be good to employ database recovery services. It would cost a few thousand dollars but is way cheaper than the cost of recreating data. In case of data loss, some steps have to be taken in order to assure safe backup and full recovery of all lost information is done.

The first important step is to choose the most appropriate database recovery. At the moment, there are three methods of database recovery.

The first one is the simple database recovery. This method is used when a database administrator decides that the transactions are not as important as the main data of the database. In this case, one only needs to save the main data and ignore the transactions that had occurred. The data can be recreated in a short time and may not necessarily need experts to do it. But it is good not to take a chance because if one is not careful, you may end up losing all the information in the database.

The second and the third method include full recovery and bulk-logged recovery. In these two methods, one has to protect both the data in the database and all the necessary transactions relating to the database. These 2 methods are more technical and sophisticated. The have to be done with experienced technicians such as data recovery specialists. In addition, the above methods need more system requirements and disk drive space. The data recovery experts will come with the necessary software to carry out recovery. This will all depend on the scope of failure experienced. If the failure is major, then they will have to take your server and perform the recovery in their labs. Otherwise, they will just run the recovery software and will be able to recover your data.

Server recovery in Kenya

3 Signs Your Server Is About to Die:

When you are keen and paying attention to some potential warning signs in Kenya  or in any part of Nairobi or even your local town and country in Africa, Europe, Asia or America, you may be able to catch a server failure before it happens. Here are 3 signs that always make me shiver a bit when they start happening on a recurring basis. If you see these, you may want to dig into the system to see if it yields any clues. At a minimum, make sure you have some good server backups in place.

datarecoveryservercrash

When we look back over years of dealing with systems, we find spontaneous server failures rare. Before hardware failures, we often see a string of random crashes. Unlike some crashes, these crashes cannot be tied to high loads, specific processes, cron jobs or other events. The system simply dies. This is a warning sign that should not be ignored.

If you have a server management provider, be sure that they log these events. At East African Data Handlers we know many companies happily hit the reboot button and consider it resolved. This approach misses this key sign of possible server failure and prevents you from proactively fixing the issues.

If you cannot find a cause for random crashes, consider migrating to another server.

File System Issues

If the file system constantly needs checks or is going read-only frequently, your server may be dying. We’ve seen many cases where file system repeatedly go read-only for no clear reason. Even after extensive repairs, the file system quickly fails again. If you see, this then a full failure may be pending.

File system maintenance is very important to both normal operations but also disaster recovery. If you backup your server using an imaging tool, like R1Soft’s CDP server, file system issues will also be present in your backups.

If you see frequent file system corruption, consider migrating to another server.

Command Line Freezes

Another thing we’ve noticed is unexplained freezes or hangs while working at the command line. On several servers that have failed, we noticed prior to the failure odd behavior. For example, you will be running system commands and they return promptly. You re-execute the same command and find it hangs for a few seconds before running. This behavior is completely random.

If you see these freezes or hangs, you will want to rule out network or server load conditions. We’ve seen failing disks or corrupt memory cause these odd hangs. In either case, this may be another early warning sign of trouble to come.

If you see unexplained freezes at the command line, you may want to consider replacing your server.

Just Advice

This is just advice based on my 10+ years of experience of working with servers. We don’t have any hard facts and there are many symptoms for the issues above. However, when We’ve ruled out the obvious and still cannot find a cause either server crashes, file system corruption or system freezes, We get an uneasy feeling. When we get that knot in our gut, we go with it and typically recommend you change your server.

Your Gut?

Do you have any gut reactions about when a server will fail? With virtualization and other technologies making server migration easier, we are more and more inclined to migrate a suspect system than wait for disaster. The peace of mind is well worth the cost. We would like to hear about your early warning signs.
