 #### Individual Accounts / Integrity of Data
 
-All modern Operating System (Microsoft Windows NT and later, macOS, all flavours of Linux/Unix) use individual accounts and permission settings on files and directories.  The ownership and permissions make sure that one owner of an account cannot accidentally or intentionally affect the data of another account.  Individual account can be made part of a group which allows collaboration by sharing data within the group.  A reasonable default setting allows the owner read/write, the group read-only, and everybody else no access.  Individual accounts shall not be shared, i.e., the password shall only be known to the person owning the account.

 Make sure that the data is properly backed up.  Temporary data which can be easily recreated may not be backed up, but everything else should be backed up daily or at least weekly.  The Department of Physics maintains some file servers which are backed up daily.  All members of the D-PHYS are invited to use these servers.
