Backup methods and tools for MySQL

January 18th, 2013 1 comment

MySQL needs to have different backup recovery system, which will prevent loss of files generated into the system. This mostly happens during upgrading of systems or integration of different networks.

Causes of crashes

There are different causes that lead crashing of the system and this makes it harder for one to recover. With a number of different solutions to use, it is wise to understand the methods that cause hitches and try different ways to prevent. Some of the common causes include

Crashing of the operation system

Abrupt and constant power failure

Crashing of the file system

Where there are issues with hardware, motherboard, or hard drive

These are the possible areas ,that lead to constant crashing of the system and this means all data stored have higher chances of getting lost but there are different methods one can use to restore the files.

How to manage using a file snapshot system

It is important for the programmer to take into account different methods that make it easier for one to get the data files in the system. This systematic process needs attention to detail in order to get recommendable results.

–  create a client program, and execute FLUSH TABLES WITH READ LOCK.

– create another shell, execute mount vxfs snapshot

–    choose first client, execute UNLOCK TABLES.

–    Copy files from the snapshot

–    Unmount the snapshot.

 

Tools used in the backup and recovery process

XtraBackup

mydumper

mysqlhotcopy

Zmanda Recovery Manager (ZRM) for My

mysqldump

mylvmbackup

ZRM with XtraBackup (and streaming)

 

MySQL backup methods and characteristics

Backup uses querying the MySQL server to get database construction and gratified information

Backup is gentler than physical approaches because the server should access database material and adapt it to logical format. If the production is written on the client side, the server must also send it to the holdup program.

Output is particularly bigger than physical backup, predominantly when saved in text setup

Backup and reinstate granularity is obtainable at the server level), database level (all tables in a, or table level. this happens regardless of the type of server of backup device.

The backup should not compose log or configuration files, or database-related files that are not part of databases.

Process of data backup and recovery process sign MySQL

Top 10 Reasons why you should use Relational over NoSQL databases

December 31st, 2012 No comments

With the introduction of NOSQL database, many people find that it is easier to shift to these databases but this does not mean they will get all the solutions that they need. It is still important to settle with the relational databases due to a number of reasons and some of the developers find that it is easy to stick to the system.

  1. With the relational database, one is investing in a low-volume and less complex applications, which makes it easier for them to handle and this means they can start to develop this application in a matter of time
  2. With the chance to do normalization with relational database, you find that it is effect to have the duplicated volumes of data in the system that you want
  3. Switching to another database is not an easy process since you have already invested in this program, bought the services. This means that you have to let go, learn a new system, and in most cases, you find that it does not solve all the matters, that you want and this means you have to go back to the SQL method. You need to learn and find what other developers have to say before you switch to a new system
  4. Just because a system is popularized by the search engine and has good marketing methods done online, does not mean that you have the chance to trust it. This is the reason why one needs to go through the reviews and find the reasons why they need to stick to the system and if they have to switch to NOSQL< the benefits they get over the relational methods
  5. Before investing in a new system, many people find that it will not meet their needs, and gets trickier to start learning another language and develop it. This is why one needs to stick to the database they have since all have faults but one has managed to stay with them due to the effectiveness and ability to control them regardless of their issues
  6. Relational databases are known to have the best declarative syntax and strong mathematical basis compared to other systems in the market.
  7. Relational databases have a well-known language known as structured query language in short, SQL
  8. Relational databases have a good existing ecosystem introduced into the channel and this means the documentation, third party vendors, binding to other programming languages, and loads of tools.
  9. Relational databases have the ability to host different bonuses like geographical databases and mechanism
  10. The relational database offers different indexing solutions, trustworthy transactional details, and extensive security installations.

Before one settles with any new system, they need to find more about the qualities and start the comparison process. Many people want to stick with relational methods due to the programming language, the effectiveness in the security methods, easy procedures and the chance to have the developing structures in place and center the programming language to the method that developer wants, making it hard for other people to crack the codes installed.

Keep in mind, that “best” database is not essentially one with a greatest number of the features, and lowest cost. For your requirements, it is raw performance for the small queries, and it is ease of the administration of database with millions of records. Also, it is very difficult to review it accurately in the small space, still, based on a few subjective criteria, and I have attempted that.

There is the commercial version, however download this free version, the fairly powerful as well as gives you a lot of features. Navicat is the fast, reliable as well as famous (millions of downloads) Administration Database tool purpose that is built to simplify the database management & reducing the administrative costs.
