There is some confusion out there on what’s a good way to back up your data. In this article we will go over several options for good ways to backup and sore your backups along with a few ways that are not recommended.

When it comes to backups storing them off site (off your server or on a secondary drive not running your system) is the best solution with storing them off site being the recommended course.

When raids come into consideration just because the drives are redundant (a lave mirror situation) there are several situations, which can cause a complete raid failure such as the raid controller failing, the array developing a bad stripe. Drive failure on more than one drive(this does happen though rarely) , out of date firmware on the drives and the raid card causing errors. Using a network storage device like our evault or a nas storege is also an excellent way to store backups off system. The last thing to consider is keeping your backups up to date. I suggest making a new back every week at minimum (if you have very active sites or data bases I would recommend a every other day backup or daily backup). It is up to you or your server administrator to keep up with your backups and make sure they are kept up to date. If you have a hardware failure and your backups are well out of date it’s almost like not having them at all.

In closing consider the service you provide and how your data is safe, secure, and recoverable. These things I key to running a successful server and website.

When considering these 2 raid options there are a few points you’ll want to consider before making your final choice.

The first to consider is your data, so ask yourself these questions:

• Is it critical data that your data be recoverable?
• Do you have backups of your data that can be restored if something happens?
• Do you want some kind of redundancy and the ability to have a failed drive replaced without your data being destroyed?

If you have answered yes to most of these, you are going to want to look at a Raid 1 configuration. With a Raid 1 you have 2 drives of like size matched together in an array, which consists of an active drive and a mirror drive. Either of these drives can be replaced should one go bad without any loss of data and without taking the server offline. Of course, this assumes that the Raid card that you are using is up to date on it’s firmware and supports hot swapping.

If you answered no to most of these questions other than the backup question (you should always have backups), a Raid 0 set-up is probably sufficient. This is used mostly for disk access speeds and does not contain any form of redundancy or failover. If you have a drive failure while using a Raid 0 your data will be lost 99% of the time. This is an unsafe Raid method and should only be used when the data contained on the array is not critical in anyway. Unfortunately with this solution there is no other course of action that can be taken other than replacing the drives and rebuilding a fresh array.

I hope this helps to clear up some of the confusion regarding these 2 Raid options. There are several other levels of Raid which I would suggest fully researching before you consider using one of them.

When it comes to managing a server remember you can never be to careful. In this day and age we face a lot of things that can damage and even take a server to its knees here’s a few things for everyone to consider.

Anti-virus:

This is a must on systems open to the net now days. There are always nasty little things floating around looking to take your server apart from the OS out. For windows servers there are a multitude of choices and I’ll just mention a few that can help protect your goods. You can use several programs such as avast (which offers a free edition), ClamWin (open source), Kaspersky , and Panda just to name a few. I would suggest before installing any of these you check links such as http://en.wikipedia.org/wiki/List_of_antivirus_software to name one that provides a list of several choices and their compatibility. You may also want to read reviews that compare the available options and give you an idea of what to expect from them. This will allow you to make an informed choice on which one works best for you. Now with linux there are also several options for this including the well known clamav which from personal experience works really well and can be installed on a variety of linux disro’s(aka distributions). It’s very simple to use and may prevent you from headache later on down the road.

Firewalls:

Firewalls are a double edged sword but are most defiantly needed. When it comes to firewalls you can protect yourself from quite a bit of headache however if setup to strict you can block positive traffic and even yourself from reaching your server but in the long run a defiant way to help protect your server from unwanted visitors. A lot of firewalls also have modules and add-ons that further assist in protecting you and securing your server. If in doubt it’s always a good idea to have a security company do an audit and even a security hardening session with your server to make sure you are protected the best way possible.

Passwords:

This is probably one of the most important this you can do to secure your server. Use strong passwords (no using password or jello is not a secure password even if it is in all caps) and if you are worried about not being able to come up with a secure one there are several password generators on the web that can come up with secure ones to assist. Passwords should contain caps letters, numbers, symbols, and should be at minimum 8 – 10 characters (the more the better). It’s the easy to remember and easy read passwords that get you into trouble.

Armed with this information and so much more on security that can be located on the web using the great and all powerful Google should be a good start to making sure you don’t have to worry about data loss and system hacks. Also remember no matter how secure you think you are make regular backups of all your important data as if you server could crash at any time.
