Ever heard of synchronous replication?
People all over the world are consumers of several basic products, but in different forms. Everyone, no matter where they are on the face of the planet or how old they are has the need to eat, to drink and to breathe.
These are our most natural urges or instincts which are indeed the commons of everybody. However, as time progressed and men became more connected with their fellow brothers, another need that is almost natural came to take a nice place in the human needs list. This is the need to know.
People don’t just want, they need information. Curiosity is the name of the game and collecting information is how you do it. The information collected is ought to be stored somewhere as the human brain can only store a limited quantity of data. So we have invented computers to assist us in storing and protecting our beloved information.
There are several methods available to use today for increasing the protection of the information we have. Synchronous replication is one of them. The more information you have and the more changes you perform on it, you’ll need a system to guarantee you full protection.
Synchronous replication here, there and almost everywhere
A common system which was and still is in use for replicating your information – whether you’re a private home computer user or a head of a department in a big corporation – is the backup tape. Like in synchronous replication a backup is done in a pre set date and time by placing a backup tape in the main server, copying the data and removing it for storage in a different location.
However, the tapes don’t provide you, the user and data owner, a full protection and a complete confidence that your information is one hundred percent protected. Today’s gigantic black-hole of a media world requires a more stable and ensuring system.
Synchronous replication can answer that call. First of all, it insures that the information replicated will be equal to the information on the main server, and this actually means that there is no chance whatsoever for you to lose even a comma from your data files. However, you should take into consideration that the synchronous replication system works best under very certain conditions.
Due to its relatively high costs it’s recommended that you’ll do the math and jump in only if you’re a financially big company or corporation. Another factor is the distance.
Note that this system is wonderful only for a short distance between the main servers to the storage protected location.
Synchronous replication – still a safety net
Even with the slight disadvantages, this highly sophisticated method for replication and protection of important and valuable information known as synchronous replication can still be used as a safety net for many firms and large corporations and enterprises.
