 +===== 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 [[rt@math.uni-hamburg.de|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: ''<nowiki>\\afs\math.uni-hamburg.de\users\it\fmsv030\</nowiki>''

 +  Backup:
