To consolidate and improve the performance of the company’s backup applications.
Like any large company, Telenor Hungary must keep track of a growing volume of data. Yearly audits check internal controls over financial reporting, which requires the company to quickly identify failed data backups. However, prior to 2016, the backup systems in use were making this difficult.
The company needed to back up tens of terabytes of data every day. This included email, and other data created by up to 100 applications for managing customer billing and payroll, as well as many other tasks. Telenor Hungary handled this data using a range of applications, including a data warehouse, Microsoft SQL Server, Microsoft Exchange, and Oracle databases, and across a range of Windows, Unix and virtual platforms.
As the volume of this data increased, it became more challenging for Telenor Hungary to meet service level agreements. For example, the company needed to complete critical backups quickly, but it took 20 hours to back up a 20 TB billing system each day.
Telenor Hungary did not have a single tool capable of backing up everything. As a result, it had implemented seven different backup applications over the past decade. These included its main backup solution – IBM Tivoli Storage Manager – native database and operating system backup mechanisms, customized scripts, and other solutions for backing up its data warehouse and virtual hosts.
The number of backup tools made it difficult to diagnose problems. To find out if backups had failed, IT staff members had to collect logs from each of the seven backup applications. This process could take up to two hours and could interrupt scheduled backup sessions. If this occurred, staff members had to perform those backups again, potentially interrupting prescheduled backup and restoration processes. This reduced the time they could spend performing other tasks.
Telenor Hungary also wanted to improve data backup and restoration efficiency. Slow tape libraries and drives affected backup, restoration, and application performance. Managing backups was expensive and time-consuming. Wanting to improve the performance and reliability of its existing backup system, the company looked for a new backup solution.
