  • Institutional storage locations (university network server)

Solution proposal according toungsvorschlag nach Imeri et al. (2023):

PC: Storing on one’s own computer

+ Maximum control
+ Data storage and transfer possible without an internet connection
– The researcher is solely responsible for security and backup
– Data recovery is impossible if the PC is lost or damaged
– Collaborative work is not possible

Mobile storage media (e.g., external hard drive, USB stick, etc.)

+ Easy to transport
+ Can be stored in a locked cabinet or safe
+ Data storage and transfer possible without an internet connection
– Risk of loss or theft
– Depending on material, can be shock- and wear-sensitive

Institutional storage locations (university server)

+ Regular data backup
+ Professional administration and maintenance
+ Institutional data protection regulations are considered
– Dependent on an internet connection
– Access is usually lost after leaving the institution

External storage locations (Cloud, Google Drive, etc.)

+ Easy to use and manage
+ Automatic backups
+ Supports mobile and collaborative work
+ Professionally managed and maintained
– Data protection is not always guaranteed
– Dependent on an internet connection
