Disk Space Management

One of a Database Administrator’s main priorities is to safeguard the data which is stored for the company or business which they are working for. This includes, but is not limited to effectively managing the disk space requirements of the business’s needs.

So. How can you effectively plan and manage your businesses disk space requirements and what should be considered when doing so?


When planning the storage requirements, it is important that you not only plan your initial storage needs, but also take into consideration future growth.

In the vast majority of cases the amount of data, and therefore the amount of storage space needed, will grow over time. Data retention periods should be taken into account, as should any data archiving processes that will help reduce the amount of storage needed.

In addition, backups and the backup retention policy needs to be considered. Backups can take up a large amount of disk space and the longer the retention period is, the more space will be required.

Since disk space carries a cost, the business needs to fine tune the space requirements as effectively as possible. Effective planning is crucial because the data requirements need to be considered with the financial costs of the hardware and lack of space is one of the main causes of system downtime and should be treated as a significant risk.

Monitoring and Managing Disk Space

Experience in the industry and the platform used is important when making sensible predictions about how much storage space will be required for both the short and long term. Monitoring the use of the space is also vital and the more historical data you hold on growth patterns, the more able you are to make accurate predictions for the future.

The potential for huge data growth needs to be considered. You may well operate with minimal growth in some areas of the database, with significant increases in others. This is all dependent on the application, number of users, customers and the transactions being processed at that time. Businesses typically have peak growth times that the DBA team should be aware of and prepared for.

And of course and revisiting your plans and reviewing the plan against your actual growth is also very important.

As a business do you know what your current disk capacity is? When you are expected to reach your capacity limit? What your data growth has been over a period of time?
