Data Retrieval: Your Own Server vs. Hosting Your Applications

Any company or individual who develops their own applications for the web has experienced data loss at one point or another. Administering your own server may seem like a great idea; but what are the repercussions of doing so? The maintenance of the data itself, having a backup plan in case of a disaster; and the recovery involved when a disaster occurs will be discussed in this article.

Let’s talk about what actually drives web based applications. Most sites that have a lot of information and resources to offer rely on databases to drive the underlying application. These applications store data including product information, descriptions, articles, pictures, movies and music in a relational system referred to as a database. The database itself is the underlying logic or medium between information; and also stores information about how different resources relate to one another. As the database grows and is developed, the need for data redundancy becomes more critical as time goes on. Not having the right backup plan in place could lead to a data disaster; causing your precious time, money and resources to go down the drain. When this happens you will require paid Server Recovery services.

Many companies store their databases on internal or local servers. There can be many benefits to having a server accessible locally. Physically being able to control a web, file or database server and maintaining that server locally might seem like a great idea; but is it really all that smart? Many hosting providers and web solution providers offer Software as a Service (SaaS).

SaaS comes in many forms as hosted applications. In simple terms, SaaS means a piece of software that can be installed and hosted on a remote system. Big deal, right? Well actually YES… it can be a big deal! First off, you don’t need to have a fancy “super doper – ultra high speed” connection at your office to host your applications. Second, you don’t need to maintain the actual server that is hosting the application. Third, you don’t need to worry about redundancy of your data as most data centers have plenty of storage for backups. However, reality of such SaaS deployments is really more complex.

SaaS deployments almost always have clustering or replication systems in place for customer data. This allows such vendors the ability to have service “continuity.” Such SaaS deployments usually always have continuous replication of user data and advanced redundancy RAID systems utilized. These backup systems are extremely sophisticated compared to smaller systems and do a lot of work throughout the day. Typical SaaS production servers handle 10,000+ customers and 100,000+ users on a single cluster.

Most SaaS applications offer some sort of backup system for its’ customers. However, the customer must execute such systems on their own. Think about this: If you needed to recover data from some earlier point in time – say three weeks ago – and given the number of simultaneous backups in flight at all times on a SaaS hosted application – you can imagine the overwhelming complexity involved in retrieving such records accordingly.

First lesson learned: Do your own regular backups, whether data is stored on your own server or through hosted applications. If your SaaS provider has an automatic export tool or an archiving function that can be written to a local file, use it by all means. Always keep at least 6 months of backup files regardless of whether you think you need them or not! Even though you use automatic export tools or other backup systems; there will inevitably always be data that is either omitted or outdated in some way.

There will always be a need to store information on computers; likewise there will always be unforeseen problems with information storage systems. Having the right plan in case of a disaster is always a good business decision. Always weigh the benefits and problems related to each solution; and never be afraid to do your own research too.

How To Sound Like You Know About Computers

July 07, 2010 By: lilybird Category: Desktop and Laptop

So, you have just bought a brand spanking new laptop, you’re excitedly strolling home from the shops and unexpectedly you run into an old adversary from university.

Until this point, you were just going to take your notebook computer home, hook it up, insert the disk the chap in the shop gave you and cheerily lay on the sofa watching clips of cats messing around with iPhones.

However, there’s a foolish pride in most people nowadays which seems to involve a necessity to pretend you know a good deal about computer systems and electronics and such and you are definitely not your father, who could not even work the timer on the video recorder.

Therefore we provide you with a quick emergency guide to faking your way to looking like a technological guru.

1) Randomly scatter these words throughout your chat: RAM, Universal serial bus, netbooks, iphone 3gs, Pentium processor chip, touchscreen notebook computer and flux capacitor. If questioned about your usage of any of these assert you have the most up-to-date version, so anything that your fellow converser claims is erroneous is just because they ‘don’t know about the newest upgrades’.

2) Attempt to always have a few spare wires with you, irrespective of what they are for. Everyone knows people who are skilled with laptops use wires.

3) Whenever the other person brings up any kind of electrical item instantly reply using the following phrase: “I guess that is fine, but I much prefer the extra features on the newest upgraded model.” If they claim the item they were discussing is the latest upgraded model, tell them you’ve got a superior prototype.

4) Make certain that whenever you talk about films or television you drop in the fact that you watched them on BluRay on your HD TV linked to your surround sound stereo. Furthermore, don’t say you watched something, say you ‘experienced’ it.

5) When you leave say that you will Tweet about your conversation and instead of saying “I’ll see you around.” say “I’ll poke you on Facebook.”

Follow these tips and soon you could be that person whom everyone rings up when their laptop breaks (just advise them to switch it off and on again), that’s cool right?
