S 6.41 Training data reconstruction<br />

Initiation responsibility: <strong>IT</strong> Security Management<br />

Implementation responsibility: Person-in-charge of data backup<br />

<strong>The</strong> restoration of data using data backups must be tested at irregular intervals,<br />

at least after every modification to the data backup procedure. It must at least<br />

once be proven that complete data restoration is possible (e.g. all data<br />

contained in a server). This ensures reliable testing as to whether<br />

- data restoration is possible<br />

- the data backup procedure is practicable<br />

- there is sufficient documentation of the data backup, thus allowing a<br />

substitute to carry out the data restoration if necessary<br />

- the time required for the data restoration meets the availability<br />

requirements (c.f. S 6.1 Development of a survey of availability<br />

requirements)<br />

When training for data restoration, the following should also be taken into<br />

consideration:<br />

- the data must be installed on an alternative <strong>IT</strong> system<br />

- different writing/reading equipment is used for the data backup and data<br />

restoration<br />

Additional controls:<br />

- Can a specialist carry out the data restoration using the existing<br />

documentation?<br />
