The size of a P: directory for an organization, etc. On his P: drive the user only sees the directories of organizations, departments, companies, associations, projects or other groups that he belongs to. Project and organization-related data can be stored on these drives. The P: drives are made available to departments within organizations, departments and other groups to be determined. On the centralized, shared storage facilities, LISA also makes storage facilities available that can be shared with others.
(The M: drive is also accessible by means of a web drive). This M: drive is accessible from the member of staff's UT workstation. Before the limit is reached, the member of staff will receive an email alert. The standard capacity of this storage is 10 GB and can be increased to 20 or 40 GB on request.
If you work for several organizations within the UT, or you move to a different organization, this directory remains the same. These documents are your own and cannot be shared with others. The M: drive is intended for the storage of your own work documents. (Therefore, if you make a backup of the data on your local storage on the centralized facility, then you actually have double security: the copy you made yourself on the centralized facility and the backup of this as created by LISA.) Each member of staff has their own storage area on the centralized facility: their own 'Home Directory', their own M:-drive. And LISA does make a backup of the data on these centralized, shared storage facilities. To back up the data on the local drives, use can be made of one of the facilities offered by LISA in the form of centralized, shared storage facilities. It is the responsibility of the employee to do this. Local drives (C:, D: etc.) at the UT workstation. No backup is made of these local drives by LISA. The total capacity provided for storing files, email, and other apps within Google Apps is 30 GB per student. Is outside the influence and responsibility of LISA. Registered with department department of other group to which it belongs. Outlook service, thus including calendar, contacts. The total capacity provided for storing email, files, and other apps within Google Apps is 30 GB per student. This document provides insight into the different applications. The method used for this also depends on the type of data. LISA also ensures that backups are made of the data and that, if necessary, the data can be retrieved from these backups. The method used depends on the type of data involved. The selected backup strategy ultimately determines how large the required backup capacity is, and therefore also determines the cost for the backup facility.Īs part of the general ICT facilities, LISA stores various categories of data. The application is taken into account when deciding which backup strategy is most suitable. The account manager will then consult with the researcher to determine which data is involved. If a researcher would like LISA to make a backup of his or her research data, then he or she can contact the LISA account manager in the faculty in question. Where research data is concerned (research data is specified in the classification guideline), there are requirements relating to backups. In the case of backups for data not falling under this guideline, the user decides how his or her data is backed up, in consultation with LISA. The level selected depends on the requirements as set out in the Classificatierichtlijn Informatie en Informatiesystemen UT In descriptions and guidelines prepared by the University Information Management Department (UIM), parameters RTO and RPO are called MTU and MTD. In both cases, LISA uses the centralized storage facilities that are accessible via Campusnet. LISA has capacity available for the saving of backups within both the standard level and the high level of storage. The data newly produced during this timeframe will need to be generated once again. RPO, maximum tolerable downtime (expressed in time). RTO, expressed in time, indicates how long it will take to replace the last backup of the data that has not yet been lost or damaged as a maximum. RTO therefore indicates how long it will take before you can use the data again. RTO is calculated from the moment LISA receives the request to restore a backup.
Two important parameters for determining such a strategy are RPO (Recovery Point Objective) and RTO (Recovery Time Objective). Because data is not or not usually static, it is important to develop a good backup strategy to ensure that data from the past can be retrieved in a structured manner.
