Remote Data Backup

Unlike regular data backup software, Remote Data Backup doesn't send backups to media attached to the computer it is backing up. Instead, Remote Backup uses remote methods such as normal telephone lines or network connections to send the backup to another computer. Fully automated, it typically sends the backup at night so the computers aren't being used. Backups are becoming more and more vital as business depend more upon computers and the data they store. Night after night, many businesses takes vast risks and are not even aware of it.
Other backup software usually misses or improperly completes essential steps that Remote Data Backup is perfect for. This is especially true with non-automated backup systems, where a company employee is responsible for performing backups. Sometimes the person is occupied with other work, the computer is in use at the scheduled backup time, or the person just forgets. Whatever the reason, most businesses do not follow their backup schedule. But with a Remote Backup system, backups are automatically completed when the computer is not in use, usually at night or some other low usage period, so you'll never be caught off guard without a recent backup.
Most data backup software is installed with a list of files for which duplicates need to be made, generally reflecting the computer's memory when the software was installed. These updates therefore miss many important files, including files that were started after the software was first used. To make matters worse, most companies do not regularly reset their backup software to ensure that all necessary files are being protected each time.
Remote Data Backup will help solve this issue by reevaluating non-stop your computer system, adding new files to the backup as necessary. Copies of files that are redundant are stored using a very sophiscated version control system that is not available in most of the other types of backup software. This fact is too important to dismiss.
Redundancy is a necessary feature for any online data backup service. There need to be multiple copies of every file, kept at every stage of development. The version provide for the strongest possible data loss protection by minimizing the amount of information that would be lost in the event of a disaster. Each file should be backed up after each session, and each copy of each file should be retrievable at any time. Large corporations back up their data this way, and Remote Backup allows small companies to have the same assurance that their data is protected.
To ensure total security, all backups are encrypted. Usually, tape backups are not encrypted; anyone who can get a hold of your tapes will be able to gain access to your payroll, tax information, customer database, and other records. Remote Backup stores this information at multiple secure sites, so that you don't need a tape backups. As a result, no disaster can completely wipe out your records, and you will soon be able to get your business computers restarted.
Unlike regular data backup software, remote data backup doesn't send backups to media attached to the computer it is backing up. Fully automated, it typically sends the backup at night so the computers aren't being used. This backup process eliminates a difficulty through the process of constantly studying the contents of your drive, modifying the set as necessary. By definition, online data backup service requires redundancy. There must be multiple copies of each file stored at different points in their development. These are called "versions". Versions aid data loss protection. Remote Backup provides a great solution to this problem: store all the encrypted data on several sites.

Dedicated Servers – Backup and Recovery Strategies for Web Hosting Companies

Author: Rodney Ringler

What kind of backup recovery strategy should a company have for its dedicated server? Web hosting companies have been debating this architecture since their existence began. It is really a question pondered by the whole IT community. There are many right solutions, dependent on your company’s ability to handle downtime. The correct solution for you will factor in the amount of redundant protection you need against the overall cost.
Before we discuss the different options for backing up and recovering your dedicated server, we should mention that the server hardware, data center, and fiber connection are all critical to reliability. This article is specifically focused on strategies to backup and recover your server’s data.
At a minimum, you can create a partition in your hard drive and backup your server weekly or monthly. There is no cost to this kind of solution, but the downsides are obvious. If your hard drive crashes, you will lose your backup as well. This kind of solution is only recommended if you can afford to lose all of your data, which most web hosting companies cannot.
Next, you can contract a remote backup service to set up offsite backups. These backups can be run daily, weekly, or monthly. The cost of this solution is around $30-$50/month depending on the web hosting provider. This option gives you a solid backup in case your hard drive crashes. The downside is that recovery time will take 6-12 hours or more depending on how much data you have. The data has to be manually copied over, and this is a slow process. If you can afford the cost, this solution is part of an overall backup system, but it is not recommended as your only solution.
The next backup option is to have a second hard drive installed on your server and have it set up to do daily, weekly, or monthly backups. Most web hosting companies that provide dedicated servers will charge between $15-$30 for a second hard drive. This is a nice compliment to the previous solution if you have the budget for both. The recovery time is faster then a remote backup. But unlike a remote backup, if your dedicated server or the datacenter are down, then you cannot access the backup. For most small web hosting companies this is not a problem. If their entire server or datacenter are down, they have larger issues to worry about. We recommend this as a complimentary option with a remote backup.
Next, a web hosting company can use mirrored RAID drives. This option will cost $50-$80/month more, but it provides the fastest possible recovery in case of a hard drive crash. You can just reboot using the mirrored drive, and you are back in business. The cost is a little higher, but this is a nice luxury. The downside of this option is that if your server is unavailable, then you still cannot reach your data. Additionally, if the hard drive becomes corrupted it will also corrupt your backup. This is why we recommend mirrored drives as part of a larger solution that includes other backup systems.
Finally, there are mirrored servers. This entails the largest cost and is really not necessary, except for those web hosting companies that can tolerate no downtime at all. In this scenario, if the server itself dies you can have another server ready to take the load. In fact, if your company is large enough, you might already need this kind of solution for performance. Some websites require multiple servers to handle the performance, and it is load balanced across them. In this case, if a server dies the system still runs. This is the best solution but it is not always necessary. And, of course it is costly.
We recommend a weekly remote backup to provide you with a fail safe version. Even if the datacenter burns down, you will have a copy of your data. To this we would add either mirrored RAID drives or a second hard drive, depending on your hosting company’s needs. If you are more worried about recovery time from hard drive crashes, which is the most frequent hardware problem with dedicated servers, then go with the RAID drives. If you are more worried about the hard drive getting corrupted, go with the second hard drive.
We hope this article provides you with the information you need to adequately back up your dedicated server!
