Backup Administrator
Performance Technologies · Athens, Attica, Greece
About The Role
We are seeking an experienced Backup Administrator (Medior to Senior) to join our Data Protection team . In this role you will design, configure, maintain and support enterprise backup and recovery solutions across our customers' environments, ensuring the integrity, availability and recoverability of critical data.
As a medior-to-senior member of the team, you will take ownership of backup infrastructure, drive improvements to policies and processes, resolve complex issues independently, and act as a technical point of reference for junior colleagues and customers alike. The ideal candidate combines deep backup expertise with a solid understanding of the wider IT infrastructure stack — virtualization, databases, storage and cloud.
Main Responsibilities
- Leading the setup, configuration and lifecycle management of enterprise backup software and hardware solutions, ensuring compatibility and integration with existing systems.
- Designing and refining backup policies and procedures — defining backup schedules, retention periods, RPO/RTO targets and disaster recovery plans in line with customer requirements.
- Monitoring the health, performance and capacity of backup environments, and performing proactive maintenance such as software updates, patching, upgrades and hardware checks.
- Troubleshooting and resolving complex backup failures, performing root-cause analysis and driving corrective and preventive actions.
- Planning and executing regular backup, restore and disaster-recovery testing and validation exercises to guarantee data integrity and recoverability.
- Producing and maintaining clear, up-to-date documentation — configuration details, runbooks, procedures and troubleshooting guides.
- Advising and supporting customers on backup and recovery best practices, handling data restoration requests, and acting as an escalation point for complex issues.
- Mentoring more junior team members and contributing to knowledge sharing within the data protection team.
- Bachelor's degree in Computer Science, Information Technology or a related field (or equivalent practical experience).
- 5+ years of proven experience as a Backup Administrator or in a closely related data-protection role.
- Strong understanding of IT infrastructure: servers, networking, storage systems and security fundamentals.
- Hands-on experience with virtualization platforms (e.g. VMware vSphere, Microsoft Hyper-V) and their backup integration.
- Working knowledge of backing up and restoring databases (e.g. SQL Server, Oracle, PostgreSQL, MySQL).
- Familiarity with backup of cloud and hybrid environments (e.g. Microsoft Azure, AWS) is a strong advantage.
- Solid experience administering both Linux and Windows servers.
- Proficiency with enterprise backup solutions. Experience with Veritas NetBackup is preferred, but experience with other platforms (e.g. Veeam, Commvault, Rubrik, Cohesity, IBM Spectrum Protect, Dell/EMC Networker) is equally welcome.
- Good understanding of technical support practices — ticket documentation, SLAs, KPIs/statistics and escalation processes.
- Excellent communication skills, with the ability to explain complex problems and resolutions clearly to customers.
- Strong customer-service orientation, time-management skills and strong attention to detail.
- Willingness to learn and adapt to new technologies and procedures as backup solutions evolve.
- Fluency in English, written and spoken.
Nice to Have
- Relevant certifications (e.g. Veritas NetBackup, VMware VCP, cloud provider certifications).
- Experience with backup automation and scripting (PowerShell, Bash, Python).
- Exposure to deduplication appliances and tape library management.
- Experience working in a managed-services or multi-customer environment.
We will offer you a friendly and dynamic working environment, in which you can develop your skills and competencies and a workplace with a strong focus on values and work-life balance.
