You use a CSR backup (CSR = Configuration Save and Restore) to back up the configuration data of a unit (Management Unit, HNC or Server Unit x86) in an archive.
CSR backups are retained when reinstallation takes place.
In a single-MU configuration, you can use a CSR backup to recreate the configuration of the respective base system as of the time of the backup.
In a multi-MU configuration, there is a difference between MU-specific and MU-global data.
For MU-specific data:
The current MU-specific data are replaced by the old data.For MU-global data:
The current MU-global data are not changed, only old, no longer existing MU-global data are restored. The MU-global data are the configured authorizations (accounts, LDAP configuration, IP based access rights), the configuration of the alarm management, the configured Application Units, the configured applications, the configuration of the FC networks, the configured SU Clusters.
Security-relevant actions
As administrator, in the SE Manager you can download configuration data backup archives to the administration PC in order to back them up in case a disaster occurs.
If required, as administrator you can also upload the backup.
The CSR backup contains base system data which is relevant to security. However, it contains no customer data from your BS2000 systems which are run on or with it.
The data collected in the archives cannot simply be used in the form it is to intrude in or compromise the system. Nevertheless, you should take care:
When managing the archives on the administration PC, ensure that only trusted persons can access these archives.
When uploading, ensure that the data in an archive is activated only on the required target system and on no other system beside this.
Recommendation: | For the purpose of data security, perform a CSR backup after every configuration change and store it in accordance with your security policy. |
Note: | A CSR backup contains no account passwords. |
