Application
This unit describes the skills and knowledge required to establish database backup and restore procedures in accordance with organisational requirements, and consistent with the database architecture.
It applies to individuals who are technical support personnel, such as help desk supervisors, information and communications technology (ICT) support technicians, database support technicians and user-support specialists.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Plan database backup and restore | 1.1 Examine architecture of database file systems and determine likely risk and failure scenarios 1.2 Determine methods for database backup and restore to mitigate likely risk and failure scenarios 1.3 Prepare backup maintenance schedules according to organisational backup and restore policy 1.4 Prepare contingency plans according to organisational backup and restore policy |
2. Undertake backup methods appropriate to database requirements | 2.1 Complete full off-line backups with acceptable downtime according to organisational backup and restore policy and procedure 2.2 Complete online file backups with acceptable downtime according to organisational backup and restore policy and procedure and organisational data security plan 2.3 Deploy redundant array of inexpensive disks (RAID) configuration aligned with the organisational backup and restore policy 2.4 Arrange off-site copies of backup files consistent with organisational back and restore procedure and organisational data protection plan |
3. Establish and test recovery points and disaster-recovery procedures | 3.1 Determine and document database recovery points based on backup methods, according to organisational backup and restore policy and procedure 3.2 Test restore process to ensure database can be restored to given recovery points with acceptable down time as specified in organisational backup and restore policy 3.3 Complete and document restoration of databases to point of failure, without loss of committed transactions |
4. Create and deploy a standby database | 4.1 Create and deploy standby databases to support critical organisational functions according to organisational back and restore policy and procedure 4.2 Prepare documentation for standby databases that meet requirements of organisational backup and restore policy |
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance but not explicit in the performance criteria.
Skill | Description |
Reading | Analyses complex textual information in order to evaluate a range of backup and restoration methods |
Numeracy | Interprets mathematical information in order to construct date and time based schedules Extracts and calculates numerical information from textual and numerical information to determine and confirm requirements |
Writing | Uses technically specific language in developing plans, schedules and documentation Articulates information, and presents this information, in a clear, concise, sequential and grammatically-correct manner, and in a writing style that is appropriate to the audience |
Oral Communication | Facilitates successful discussions by employing effective listening, questioning and summarising skills to ensure that appropriate information is gathered |
Navigate the world of work | Recognises and follows, both explicit and implicit protocols, and meets expectations associated with own role when complying with organisational and security standards, and guidelines |
Get the work done | Takes responsibility for planning, sequencing and prioritising tasks, and own workload for efficiency, and for effective outcomes Makes routine decisions, and implements standard procedures, for routine tasks, using formal decision-making processes for more complex and non-routine situations Addresses less predictable problems and initiates standard procedures in response to these, applying problem-solving processes in determining a solution Uses familiar digital technologies and systems to access information, search and enter data, and code, present information and communicate with others, cognisant of data security and safety |
