Taking care of storing your data and making timely backups is a crucial step of good research data management practices because it is not possible to archive something that has been lost.
In case you are using a faculty’s network share (like MyDocuments folder), you are safe. Please note that if you use your university managed laptop without connection to the network, no backups will be made! Use EduVPN to prevent this. If you store data elsewhere (for instance on your unmanaged laptop or private computer), you are responsible for making backups yourself, preferably by synchronizing with OneDrive or Surfdrive.
To back up your data, think of making use of the storage facilities offered to you by the FdA, LU.
