Glossary
Archiving corresponds to temporary data storage. In this process, a snapshot of all stored hard disk data, i.e. a complete copy of the data stock, is taken. The storage of such data can range from a few months to several years. The archived data is automatically deleted at the end of a set period.
As described in the backup procedure, it must be possible to perform archiving under system and user control.
Please note that the IT Service Center does not currently provide archiving.
The term "backup" describes a procedure with which a hard disk inventory can be restored until immediately before a possible error occurs. This failure can be a hardware defect or an unintentional deletion of data. In general, data is changed under the same name, so the backup procedure must also allow the additional storage of different versions of data sets with the same name.
The backup procedure is primarily used to ensure regular operation and to restore data sets that have been destroyed by operating errors. The backup procedure can (and must) be carried out very frequently in order to guarantee that the data stocks are as up-to-date as possible. If only data that has changed since the last backup is backed up in a backup procedure, this process is generally referred to as an "incremental backup".
The client is a program or nowadays colloquially a computer such as a workstation that requests a service from a server (see below). The client software is usually installed on user-controlled computers [client = client].
The node name is the name that the ITS assigns to you. This is usually your computer name. You will find this name on the section you received from the ITS after logging in with your password.
The term restore describes a procedure with which data sets can be restored from a backup procedure according to their name and change status. The restoration of an entire hard disk inventory is generally the task of the system administration. The user usually notices little of the restoration work apart from a downtime of the file server. User-controlled restore involves the restoration of individual data sets by the user themselves. This process can be carried out by the user independently of the system administration.
Restoration of archived data
Access to archived data should only be possible for the person who carried out the archiving. If the archiving was carried out by the system administrator, restoration can only be carried out with the approval of the system administrator by the owner of the data. This makes it possible, for example, for a project manager to restore older project data independently of the owner.
Data that has been archived under user control can be restored independently by the user.
