Backups

For staff

A backup means a copy of data that is stored on a data carrier or within an application. Such copies are made as a preventative measure in order to ensure that no important data will be lost in the event of the data on the original data carrier being lost, becoming damaged or containing the wrong information (through the correct information being overwritten, rendering the data worthless).

DESCRIPTION

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.

Two important parameters for determining such a strategy are RPO (Recovery Point Objective) and RTO (Recovery Time Objective).

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.

RPO, maximum tolerable downtime (expressed in time). The data newly produced during this timeframe will need to be generated once again.

LISA has capacity available for the saving of backups within both the standard level and the high level of storage. In both cases, LISA uses the centralized storage facilities that are accessible via UTnet.

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 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. Only Normal Quality storage can be used.

Where research data is concerned (research data is specified in the classification guideline), there are requirements relating to backups. No RTO and/or RPO is specified. 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.

The account manager will then consult with the researcher to determine which data is involved. The application is taken into account when deciding which backup strategy is most suitable. The selected backup strategy ultimately determines how large the required backup capacity is, and therefore also determines the cost for the backup facility.

CONDITIONS

The backup facility can be used for data on any server connected to UTnet. It is preferable if the server in question is managed by LISA, but this is not strictly necessary.

Under conditions to be established in consultation with LISA, the backup facilities may also be used for data stored on the hard disks of desktops, notebooks, external hard drives and USB sticks.

A backup is not the same as archiving. Archiving is the long-term storage of selected data. This service is not provided by LISA, but is the responsibility of B&A (Library and Archive).

SUPPORT

It is always possible to request the Service Desk ICT to retrieve deleted or lost data. The period within which this is possible is given under 'Backup storage time' above.

For support, use the self-service page and the manuals. If you have any further questions and in the case of malfunctions, contact the Service Desk ICT.
