No matter how experienced or reputable a business may be, whether an organisation is global or just starting out, data is one of its most precious assets.
The loss of a database can lead to financial and reputational damage, to say nothing of the potential for legal penalties, so it is essential that all information is secured and backed up to protect from damage, theft or simple misplacement.
Most database administrators (DBAs) will have their time consumed by the need to ensure performance is optimised, as opposed to formulating backup plans. However, recoverability needs to be a business priority – after all, if you can’t save your database after a potential disaster, then speed of access will cease to be problematic.
A DBA is responsible for keeping a firm’s databases accessible, secure and accurate, and the bedrock to all of this is a robust backup and recovery plan for the business.
A whole host of malfunctions can occur, potentially leading to system failure. The following issues threaten the integrity and availability of the database, and each can be prevented to some extent by UPS (uninterrupted power source) systems, mirrored disks and failover technology, but an unexpected failure can leave a network dead in the water.
Database failures can be separated into the following three areas:
Application failures occur if scripts or programmes are executed at the wrong time, off an incorrect input or in the wrong order. The failure usually leads to corrupt data which demands a database recovery or restore. Time is of the essence when applications fail, as their prolonged malfunctioning can result in extended damage to the database.
Instance failures happen if there has been an operating system failure, an internal exception or another software-related database malfunction within the database management system (DBMS). Sometimes, such a failure can cause data corruption which in turn will require recovery, but more often than not data is not damaged. The DBMS just has to be rebooted to return to business as normal.
Media failure includes damage to disk storage devices, tape degradation, deleted data files and file system failures, each of which is likely to lead to data damage. Albeit a rare occurrence, data can also become corrupted through damaged memory chips.
If a media failure has taken place, the database’s unreadable valid data, readable invalid data or referential integrity may become violated. Subsequent outages can be navigated by using Dell EMC NetWorker or other modern disk technologies.
To put themselves in the safest position, businesses need an online backup service so that critical information can be accessed without restrictions on time or geographical location.
A backup plan’s flexibility will drive cost efficiencies once initial outlays have been made, because in-house storage is typically draining on IT resources, after tapes, storage, maintenance and protection have been factored into budgets.
Cloud storage services stand alone when it comes to protecting against natural disasters and other phenomena that threaten to undermine the foundations of a business’s data stores. Automated backup and comprehensive file management are just two features that galvanise storage, without extra responsibility falling on the shoulders of IT administrators.
These aspects are particularly beneficial to growing businesses surviving on limited resources because compromises needn’t be made on the quality of database backup systems being used.
Years ago business servers dealt in gigabytes, but this has escalated into a terabyte or more of data on a single database server. The bigger picture sees data in constant demand, with IT admins vying for higher processing speeds to optimise IT performance so that organisations can stay competitive.
In such a climate, one false move could be fatal for a business, which is why only a comprehensive database backup solution will suffice.
