Request more disk space

All requests for disk space are subject to review. You can request to have your disk space increased in either of two ways:

  • Use the online form.
    You will be prompted for your BU login name and Kerberos password. If you are a student, you will be asked to provide the name of your faculty sponsor.
  • Use the print form.
    This form is in PDF format and includes instructions. Note: If you are a student, you must have the course professor or your advisor sign the form before you submit it.
