MySQL Backup and Recovery Issues
There can be numerous ways your MySQL in database server can get corrupted despite the best of software and proficient users. Nevertheless MySQL recovery is not a complicated procedure especially in the presence of reliable backups.
InnoDB, the leading storage engine for MySQL has an automatic built-in recovery system that for large part operates very seamlessly. Whenever the database hosting goes down, InnoDB takes charge and tries to fix issue by running the log file from its last timestamp. In nine out of ten cases it actually succeeds. The not uncommon situations like and operating system crash or power failure provide instances where InnoDB itself takes care of tedious data recovery. However in the eventuality of InnoDB failing in providing automatic repair solution, the overall database will not start.
No less significant is the fact that regular backups of your database should be scheduled. Quite helpful is mysqldump utility for making backups of data as a snapshot in any available point of time. In order to create a “dump file” of MySQL database you can use the following command:
shell> mysqldump --single-transaction --flush-logs --master data=2 \
--all-databases > dump.sql
The output file can be named in any manner – in the above case it is named dump.sql. This dump.sql file consists of the tables, data, structures of all databases entirely backed up into an SQL text file, dump.sql.
In the above command “–single-transaction” option is particularly for InnoDB tables. This option carries out an online backup that allows no locks on tables.
Further to incremental changes have to be saved if you wish to make incremental backups, This process is best achieved by employing binary logs. It is advisable to start MySQL always with the –log-bin option to enable that binary log. In the mysqldump command referenced above there is a “–flush-logs” option which allows the server to flush out its logs. These logs can be scheduled to be flushed incrementally between dump backups to hold entire data changes made since the time of backup.
Let’s suppose you have a case where your database experiences a terrible crash. It is simple to restore If you have regular backups along with binary logs, restoring is not actually difficult. To begin with take restore to the last full backup which you have using the following command:
shell> mysql < dump.sql
This makes for restoration of data to the point it was at your last mysqldump backup. In order to restore various changes arisen since then, employ incremental backups from the binary log files that are clearly listed in the data directory of MySQL server (in our present example, logfilename-bin.000001 and logfilename-bin.000002).
shell> mysqlbinlog logfilename-bin.000001 logfilename-bin.000002 | mysql
Eight Core Processors from IBM Hit the Market
The Power 7 processor was finally launched by IBM recently. The new processor chip has eight cores and each core can run four threads! What does that mean? It means that the new processor can handle 32 tasks at the same time which is four times the number of cores on the older Power 6 Chip. The General Manager of IBM’s Power Systems unit, Ross Mauri said, the new chip would run between 3.0 GHz & 4.14GHz. It is slated to come in four, six or eight cores.
The new Power 7 chip would quadruple the energy efficiency and will run Operating systems including enterprise Linux, and AIX offered by Red Hat and Suse. As the latest chip comes with a TurboCore Technology using which customers can crank up the speed of active cores for better performance.
The new Processor chip has a Unique Intelligent Energy technology that turns off sections of the system to save energy. Though nobody is aware of the price of these “world’s fastest processors”, it is clear that these are aimed for financial and electric industries that require servers with continuous uptime.
Industry analysts fear that this latest launch from IBM could kick off a new battle in the high-end microprocessor market where competing companies includes the likes of Itanium chip maker Intel and Sun Microsystems of the Sparc chip fame.
HostGator Achieves Stellar Growth of 50 Percent
HostGator, the hosting company that grew from a dormitory room of Brent Oxley in Florida n 2003 has risen to unbelievable proportions. HostGator is ranked 21st on the 2008 Inc. 5000 listings and has 200,000 clients worldwide and has grown in large part due to word of mouth publicity.
In a recent interview with Global Industry News, HostGators’ Customer Service Manager, Douglas Hanna announced “The number of customers we have increased by more than 50% over the course of 2009”. This is another record for HostGator in the year 2010. Tracing the reasons of such huge growth, Douglas remarked that it came majorly from word-of-mouth advertising of satisfied customers who ‘continue to refer us to their friends, family, and co-workers.”
The Founder CEO Brent Oxley in one of his latest interviews explained at length the reasons behind this phenomenal success, : Our customer service is definitely an important differentiator. There aren’t many companies that provide 24/7/365 US-based support over the phone, email, and live chat in the web hosting industry, much less at our price point. We also have a competitive set of product and service offerings that give our customers the tools they need to succeed on the Internet and get the most out of their web hosting. A good product lineup coupled with good customer service is something that has worked very well for us so far.”

From Presentation to Production: Putting Virtual Dedicated Servers to work for you
The benefits of the Virtual Dedicated Server, lies in the word “dedicated”. Dedicated hosting means that the full power of the server is available to the buyer. Hyper-V uses virtualization to host multiple Hyper-V virtual dedicated servers on the same physical server, however, each Hyper-V virtual dedicated server is as good as a dedicated server of the same power specification.
You will also find that Hyper-V virtual dedicated server allows the choice of a variety of OS on each Hyper-V virtual dedicated server. The OS could be Microsoft OS or Linux or FreeBSD and others.
Service level agreements can be purchased with plans for Hyper-V virtual dedicated server hosting which include monitoring upgrades, OS maintenance, security patches and quite often daemon updates.
High end virtual dedicated server hosting providers are generally multi-homed which provides for redundancy in the event a server should go down. This includes events such as natural disasters such as floods, perhaps in the instance of a hurricane. In an instance such as this a data center at a different location will automatically kick-in meaning absolutely no downtime.
A few of the extra benefits of VDS include automatic restoration of operating systems. This may be used to revert the server back to its original configuration and a serial console, which can be utilized to access the server if normal means don’t work, and a remote back-up space.
Perhaps the single largest benefit to any company making use of Hyper-V virtual dedicated servers is the cost efficiency factor. It is far more cost effective to build multiple virtual dedicated servers than it is to build physical dedicated servers. IT departments in any business are able to maintain the same performance levels, security and reliability at a far reduced cost. At the same time each virtual server is loaded with its own OS and software.
