Backup
Researchers and research administrators must have a backup strategy to recover data after loss and/or to recover data from a particular time. It may not be possible to store the data in the State and University Library. In such cases a suitable place has to be found for backup of the data. Backups of more than one copy should be performed regularly, and should be housed remotely from the main data storage. The backups should be labelled and well organised to facilitate any data restoration process.
Backup security requires further mention. If the data is sensitive then it should not be stored on a computer that is connected to the internet, and preferably not connected to any network. If the data needs to be destroyed at the end of a project then consider what level is required – a hard drive will need to be overwritten several hundred times to ensure that no data can be recovered.
The lifetime of backups should also be considered. Burned optical discs have average lifetime of two years, and five years if kept in a cool dark place.
It is a good idea to check with the IT staff to find out how often they backup, what is the maximum amount of data they can backup, and how long they keep old backups.
You may need to maintain your own backups if:
- There are no services available to you
- You have valuable data that you do not trust with other people
- You have sensitive data that you cannot store on unsecure computers
