Description

All relevant data should be saved in a data backup regularly. Due to redundant data storages the loss of one data set can be compensated by using the backup data. Thus the ongoing operability of the utility is ensured.

Comments

All relevant factors of influence on the process of data backup generation must be documented, e.g. the amount and time of changed data, availability requirements or similar. If applied, the requirements for online data backups, e.g. in clouds, must be determined (e.g. location of storage, methods of authentification, etc.). The backup data should be encrypted, furthermore the location of the backup data should not be the same as the location of the original data.
