Microsoft (MS) SQL Server is a database server that works in saving and finding data by other software apps which can run either on one or separate computers in a network. Microsoft’s SQL Servers features a dozen different versions for different sectors and their workloads both small and large. Microsoft SQL Servers started in the late 1980swith the SQL Server 1.0 and recently released their 2017 version, which supports different platforms, more recently with Linux.
Microsoft SQL’s versions are both contemporary systems and customized editions. Enterprise Edition has the core database and add-on services and manages large databases and logical processors.SQL Server Standard also has the core database but has fewer active instances lacks high-available functions including adding memory as the system runs. Business Intelligence is made for advanced business management with standard and business intelligence specialties including PowerPivot, the BI-Semantic Model, Master Data Services, and xVelocity statistical analysis. With the specialized versions, Azure SQL Database is a cloud-based server for MS Azure, the SQL Server Developer which is free but limited to be only a development and test system, SQL Server Fast Track works for large-scale data storage and business intel processing, and SQL Compact is an embedded database system has a limited, but powerful size that works for mobile settings.
The need for a good backup and restore plan is as important as the saving of data itself. The MS SQL server automatic backup system has multiple ways to backup all data. Full database backups include all data including listed tables and transactions and do a total restoration to before the disaster. Differential backups have data that changed since the previous backup done and is used with the last complete backup. A transaction log backup mentions every change in a database since the last backup and ensures database recovery to a certain point before a disaster. File backups are most useful for massive databases; copy-only backups are used mainly to backup a system without changing how it works so it can restore it to another database. The purpose of a copy-only backup is similar to a full database with the difference of being that the copy version will be ignored when the full backup is done completely with its history of changes.
Backups should not store in the same place with the main files in case of failure, in which the drive won’t be able to restore it. If the backup is not listed, SQL will keep the files in the default backup location. The automatic backup system prevents must be set up through the creation of a schedule so the system knows when to engage in backup and not fall behind with keeping the information. It will only work when the backup is successful in a test setting and verified that the data can be restored as required for a recovery strategy.
When it comes to disaster recovery with cloud-based systems like N2WS, the Microsoft SQL fits in connecting with platforms to help businesses with all types of data loads. Big or small, it is helpful for everyone for any business in making sure important info is kept and never lost when a disaster takes place.
