Complete database backup and restore

Assessment tool

Version 1.0
Issue Date: March 2024


This unit describes the skills and knowledge required to establish backup and recovery 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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

ELEMENT

PERFORMANCE CRITERIA

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Review the database architecture to plan backup and recovery

1.1 Examine the architecture of a database file system

1.2 Determine the most appropriate methods for backup and recovery

1.3 Identify and examine the likely or possible risk and failure scenarios

1.4 Prepare a backup maintenance schedule

1.5 Prepare a contingency plan

2. Determine backup methods appropriate to database requirements

2.1 Evaluate the range of backup and restoration methods, based on organisational and security standards, and on the assessment of likely, or possible, failure scenarios

2.2 Complete full off-line backups according to organisational and security standards, with minimal down time

2.3 Complete online file backups, as determined by organisational and security standards, with minimal down time

2.4 Employ disk mirroring and redundant array of inexpensive disks (RAID) hard disk configurations to keep copies of files

2.5 Arrange off-site copies of backup files

3. Establish recovery points and disaster-recovery procedures

3.1 Determine database recovery points based on the backup arrangements, according to organisational guidelines

3.2 Test the restore process to ensure that the database can be restored to a given recovery point, with minimal down time

3.3 Complete the restoration of the database to the point of failure, without loss of committed transactions

4. Create and deploy a standby database

4.1 Create or set up a standby database, in order to meet organisational guidelines

4.2 Implement a standby database to support critical business functions

4.3 Prepare the documentation for a standby database

Evidence of the ability to:

determine and prepare the appropriate methods for backup, maintenance and recovery, including a contingency plan

implement the backup and restore procedures, with minimum disruption to the business

create, implement and document a standby database.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

To complete the unit requirements safely and effectively, the individual must:

explain the basic principles of:

diagnostic tools

structured query language (SQL)

databases

tuning methodologies

outline and apply the principles of:

backup and recovery methods

database administration

database security

open file backup procedures and restore operations.

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the database field of work, and include access to:

equipment and materials

documentation standards

backup and recovery policies

sites with a representative range of current industry standard software and diagnostic tools

database package with data

technical records

organisational guidelines

vendor documentation

the server, and a networked personal computer, on which to conduct the backup and restore procedures.

Assessors must satisfy NVR/AQTF assessor requirements.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
