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.
