RAID stands for Redundant Array of Independent (sometimes Inexpensive) Disks. There are a number of different types of RAID available. Right now the most common arrays that you will see are RAID 1, RAID 5, and RAID 10. The basic purpose of RAID is to provide redundancy, if one disk fails, the other drives essentially take over until the failed drive is replaced. RAID 1 and RAID 10 can both survive multiple drive failures, RAID 5 can survive a single disk failure. While redundancy is the main benefit of a RAID array, it is also one of the cons because in the case of data corruption, the corrupted data is written to all drives on the array.

Backups on the other hand protect against data corruption and loss, but don’t provide true redundancy. You have a couple of options with backups, you can store them locally on a secondary or on one of our highly redundant backup servers. With backups I highly recommend doing daily incremental backups and weekly full backups. That is where my argument for separate backups in addition to the RAID array comes in. If data is corrupted on the RAID array the backups that were not affected by the corruption can be restored and you are back in business.

I highly recommend having both solutions in place. No matter where your server is hosted, hard drives fail, it is inevitable. When and how, and whether or not there will be any warning is harder to predict, data corruption is always a possibility. Having as much redundancy as possible is simply the best practice.

1.      Install the Alexa toolbar or Firefox’s SearchStatus extension and set your blog as your homepage. This is the most basic step.
2.      Put up an Alexa rank widget on your website. I did this a few days ago and receive a fair amount of clicks every day. According to some, each click counts as a visit even if the toolbar is not used by the visitor.
3.      Encourage others to use the Alexa toolbar. This includes friends, fellow webmasters as well as site visitors/blog readers. Be sure to link to Alexa’s full explanation of their toolbar and tracking system so your readers know what installing the toolbar or extension entails.
4.      Work in an Office or own a company? Get the Alexa toolbar or SS Firefox extension installed on all computers and set your website as the homepage for all browsers. Perhaps it will be useful to note that this may work only when dynamic or different IPs are used.
5.      Get friends to review and rate your Alexa website profile. Not entirely sure of its impact on rankings but it might help in some way.
6.      Write or Blog about Alexa. Webmaster and bloggers love to hear about ways to increase their Alexa rank. They’ll link to you and send you targeted traffic (i.e. visitors with the toolbar already installed). This gradually has effects on your Alexa ranking.
7.      Flaunt your URL in webmaster forums. Webmasters usually have the toolbar installed. You’ll get webmasters to visit your website and offer useful feedback. It’s also a good way to give back to the community if you have useful articles to share with others.
8.      Write content that is related to webmasters. This can fall in the category of domaining and SEO, two fields in which most webmasters will have the Alexa toolbar installed. Promote your content on social networking websites and webmaster forums.
9.      Use Alexa redirects on your website URL. Try this: http://redirect.alexa.com/redirect?www.bizzhost.com . Replace bizzhost.com with the URL for your website. Leave this redirected URL in blog comments as well as forum signatures. This redirect will count a unique IP address once a day so clicking it multiple times won’t help. There is no official proof that redirects positively benefit your Alexa Rank, so use with caution.
10.      Post in Asian social networking websites or forums. Some webmasters have suggested that East Asian web users are big Alexa toolbar fans, judging by the presence of several Asia-based websites in the Alexa Top 500. I suggest trying this only if you have the time or capacity to do so.
11.      Create a webmaster tools section on your website. This is a magnet for webmasters who will often revisit your website to gain access to the tools. Aaron Wall’s webpage on SEOTools is a very good example.
12.      Get Dugg or Stumbled. This usually brings massive numbers of visitors to your website and the sheer amount will have a positive impact on your Alexa Rank. Naturally, you’ll need to develop link worthy material.
13.      Use PayperClick Campaigns. Buying advertisements on search engines such as Google or Exact Seek will help bring in Traffic. Doubly useful when your ad is highly relevant to webmasters.
14.      Create an Alexa category on your blog and use it to include any articles or news about Alexa. This acts as an easily accessible resource for webmasters or casual search visitors while helping you rank in the search engines.
15.      Optimize your popular posts. Got a popular post that consistently receives traffic from the search engines? Include a widget/graph at the bottom of the post, link to your Alexa post or use Alexa redirection on your internal URLs.
16.      Buy banners and links for traffic from webmaster forums and websites. A prominent and well displayed ad will drive lots of webmaster traffic to your website, which can significantly boost your rank.
17.      Hire forum posters to pimp your website. Either buy signatures in webmaster forums or promote specific articles or material in your website on a regular basis. You can easily find posters for hire in Digital Point and other webmaster forums.
18.      Pay Cybercafe owners to install the Alexa toolbar and set your website as the homepage for all their computers. This might be difficult to arrange and isn’t really a viable solution for most. I’m keeping this one in because some have suggested that it does work.
19.      Use MySpace . This is a little shady so I don’t recommended it unless you’re really interested in artificially inflating your Alexa Rank. Use visually attractive pictures or banners and link them to your redirected Alexa URL. This will be most effective if your website has content that is actually relevant to the MySpace Crowd.
20.      Try Alexa auto-surfs. Do they work? Maybe for brand new sites. I think they are mostly suitable for new websites with a very poor Alexa rank. Note that there be problems when you try to use auto surfs alongside contextual ads like Adsense. They aren’t also long term solutions to improving your Alexa Rank so I suggest using with caution.

Backup Backup Backup

If you’ve been diligent with your backups, you’ve got a lot of insurance to fall back on yet always make the latest backup. If you haven’t, before you do anything else, do a backup now. Backup anything and everything you can and don’t forget your database if your site relies on it. Save at least 2 copies and store them separately. One for you to work with, and the other as an archive. Do not underestimate how easy it is to copy over these files as you make changes or simply mess it up.

If you’re moving to a host who has as different control panel, make a manual backup by downloading all your files because different control panels may not be able to restore the backups made by your old host. They also have different directory structures so your file trees will be in a mess. If you need to, make a small note file with notepad with memos for you to remember the old server configurations. This will help you as you make changes on your new host server and save the confusion moving back and forth between hosts. Remember to make the correct transfer type (ASCII or Binary) as you download. If your download is not right chances are you’ll have a tough time getting your site to work on the new host server.

If server logs are especially important, remember to backup those too. There is no good way of moving logs yet because different hosts may log statistics differently. So the best thing to do is to download it and use a log analyzer on your computer to make references to later on.

Gather Odds & Ends

1. A Good FTP program which you should have by now
2. Get your new host server’s DNS
3. It’s also helpful to have a script that tells you the server environments installed on your new host server for quick references.
4. Get the temporary URL on your new host so you can check your site before you make a DNS change.
5. If you have your host control the domain inform them not to change your DNS until you tell them to.
6. If you run scripts:
- Get a copy of the original installation guide and the script. Sometimes after moving the scripts just do not work right so you might need to install the script from scratch.
- Get a list of all the server paths such as Perl, Sendmail and home directory on your new server.
- If your script needs special server modules or programs ensure they are installed and where. Even though these might be covered before you ordered the account with the host but sometimes your host has removed it or haven’t installed it yet.

Inform Your Visitors

It is common and good practice to inform your visitors and customers of the server move. If you run a e-store, this helps assure your customers you have not fled with their money if there is any downtime. Also give an alternate email so you won’t lose emails in the transfer. You might also want to give periodic updates prior, during (if there is downtime) and after. If your site is large, doing this is helpful because your visitors can alert you whenever there is a part of the site not working.

Moving Day

Try to schedule the move at a time where there’s least traffic. Backup again just before you do the move so you’ll have the latest data. Start by first copying or creating your custom error pages onto the new host server. Put a small note in there about the move. You can always remove it later. Then upload the most visible parts of the site first i.e the main pages then move on to the less critical parts of the site. If you have a large site with many divisions you might want to split them across different days and instead move the least critical first. Just ensure you always do a backup before you do any moving. Use the temporary URL to check your site, visiting as many pages as you can.

Changing DNS

Once you’re satisfied, change your DNS over. This typically takes about 24-48 hours so you have time to make some minor changes if need be. You might want to also take this time to modify your old site’s error pages to inform your visitors of the move and give a new URL if there are URL changes. To help you determine if the DNS has resolved, make a small change on the new pages to differentiate between the old and the new.

Monitor

After you’ve moved and the DNS resolved, do not release the old account yet. Keep it as long as two weeks running concurrently. Go back and check the old servers for activity. Check your old email account and if you have a web based contact method on the old server check to see if any communication is left there. Once you’re comfortable all email and traffic is correctly directed to the new host server, you can cancel that account.
