Downtime avoidance and disaster recovery are established fields in server administration, and building a system with high availability can take enormous investments. Nevertheless, if you understand the basic factors that affect downtime, you can start to form an effective plan for your business.
Use the Right RDBMS
Ideally, your business should use scalable relation database management software (RDBMS) that will adapt as you grow. When you begin building your database, you may only need an RDBMS application that supports several simultaneous users, but this will likely change over time. Using an appropriate RDBMS will limit chances of corruption, dropped tables and other issues that could lead to downtime.
Carefully research RDBMS options and keep your system up to date. Remember to back up your databases before applying any major software updates.
Use the Right Hardware
Likewise, you should use an appropriate server. Many businesses use virtual servers for their scalability and dependability, and depending on the size of your business, this might be the safest option.
If you have onsite hardware, make sure to choose an appropriate RAID level. Treat hardware failures as quickly as possible and consider nested RAID servers that offer several levels of redundancy if your database has high availability requirements.
If your business needs constant database in order access to function, you need hardware that will be able to sustain several hard drive failures without compromising activity. Be willing to invest; high availability hardware is often expensive, but it is a necessary investment.
Avoid Database Loss with Frequent Backups
While this sounds obvious, many businesses do not keep useful backups. Instead, they depend entirely on system redundancy, only creating occasional backups of critical databases.
This is a serious oversight. Your business needs to back up databases to the cloud, a tape library or another archival storage device in order to avoid data loss. Multiple hard drive failures, data corruption and other issues can push your system past its point of redundancy.
Each year, Secure Data Recovery Services' engineers treat hundreds of failed RAID servers from businesses that did not have working backups. To avoid downtime and data loss, you need to keep your backups automatic and consistent. Check your backups occasionally and have a plan in place to restore your servers after a disaster. For the best possible protection, keep at least one copy of your database files offsite.
Know How to Deal with Data Loss
If you do lose data, remember not to panic. Most databases are completely recoverable, and Secure Data Recovery Services' engineers regularly work with logically damaged databases and physically damaged server hardware. Our experts can help you avoid downtime, but the actions that you take following system failure can drastically affect the chances of a full data recovery.
Never attempt to repair your own hardware and never attempt a second RAID rebuild after an initial rebuild attempt fails. Do not run data recovery software on your databases; most tools are not outfitted to handle database repair and recovery, and many tools can cause additional corruption and damage.
Call Secure Data Recovery Services as soon as possible and speak with a database recovery expert. Have the basic details of your system available, including the name of your RDBMS application, the approximate size of your databases and an overview of your hardware. We are one of the only data recovery companies with 24/7/365 emergency database repair and data recovery services, and we understand the potential costs of downtime. Our engineers will work with you to keep your business running after a major data loss event.
