Tivoli Storage Manager for UNIX Backup-Archive Clients Installation and User's Guide

Saving Access Permissions

When you back up your files, Tivoli Storage Manager also saves standard UNIX access permissions assigned to the files. Depending on your operating system, it also saves extended permissions. For example, for files on an AIX workstation, Tivoli Storage Manager saves access control lists.

If you use the AFS or DFS versions of the dsm and dsmc commands (dsmafs and dsmcafs for AFS, dsmdfs and dsmcdfs for DFS) to back up AFS or DFS files (on an AIX workstation only), Tivoli Storage Manager also saves the access control lists that exist for each AFS or DFS directory. If you perform a command line backup of AFS or DFS files using the non-AFS/DFS versions, Tivoli Storage Manager backs up the files and standard UNIX access permissions, but does not save the AFS or DFS access control lists for directories. See Using the AFS/DFS Backup Clients for more information.

Note: It is possible for an Authorized User to back up files for another user, but this should not cause ownership conflicts. The backup server will properly record that the file belongs to the original owner. The Authorized User does not need to grant the other user access to the backup versions.
