Backup
The Informatics Computing Centre provides for all central server a multi-step data backup. This is divided into:
- Version assurance for home and project data on "snapshot" methods of the current server operating systems . Here, both accidentally deleted data as well as past file-/directory versions can be restored by the users themselves again
- Incremental tape backup for home and project data - even for the older server systems - with a defined retention time of 1 year
- Full backup of the home and project data to tape for the timely reconstruction of the data sets in the case of recovery of user accounts or in case of a limited hardware failure (eg memory system defects)
- Full backup of the critical server systems themselves on tape and - as far as possible - as a disk-based emergency - copy (eg RCC ) for the case of a disaster (eg fire / water damage)
