Access Problems

When a new user account is added to a computer, sometimes this account can't access the AFS after being logged in to the computer.
A solution was found by Lena: Solution

Daily Backup

For all directories stored in the AFS a daily backup is performed. In this way its always possible to access yesterdays version of your data. The 'public'-tree directories are also backuped daily in the AFS but are not hard-linked. If data from the 'public'-tree is needed please contact the IT-Group

Important On Windows the following paths must be modified. Each slash '/' must be replaced by a backslash '\' and the backslash at the beginning of the path must be doubled.

Example: /afs/math.uni-hamburg.de/users/it/fmsv030/ has to be written as: \\afs\math.uni-hamburg.de\users\it\fmsv030\

  • Normally, Home-Directories are readable only by the owner.
  • WWW-Directories can be accessed via WWW but normally only by their owner.
  • Public-Directories can normally be read by all users (worldwide!).

Normally, because the owner can modify the access rights for his directories. (e.g. expand rights (permissions) for the Home-Directory or reduce rights (permissions) for the Public-Directory)
