A storagepool is a collection of disks or RAIDs with similar properties that are managedtogether as a group. The group under which the storage pools are managedtogether is the file system. The automated placement and management of files onthe storage pool level is done by policies. A policy is a set of rules that describesthe life cycle of user data, based on the file’s attributes.Related tasks“Backing up Solaris Zettabyte (ZFS) file systems” on page 154On Solaris SPARC and x86 systems, ZFS is a transactional file system, whichmeans that the file system state is always consistent on disk.

You do notneed to understand this information to use Tivoli Storage Manager for basic work.Authorizing another user to restore or retrieve your filesYou can authorize another user on the same workstation or a different workstationto restore backup versions or retrieve archive copies of your files. This permits youto share files with other people or with other workstations that you use with adifferent node name. To authorize a user on another workstation to restore orretrieve your files, the other workstation must be running one of the UNIX clientsand must be registered with your Tivoli Storage Manager server.Note: Mac OS X can only restore Mac OS X nodes.To authorize another user to restore or retrieve your files:1. Click Utilities → Node Access List from the main window. The Node AccessList window appears.2. Click the Add button. The Add Access Rule window appears.3. In the Add Access Rule window, select an item in the Permit Access to field tospecify the type of data that the other user can access. You can select eitherBacked up Objects or Archived Objects.4. In the Grant Access to Node field, type the node name of the user’s hostmachine that can access your data.5. In the User field, type the name of the user on a node who can access yourdata.6. In the Filespace and Directory field, select the file space and the directory thatthe user can access. You can select one file space and one directory at a time.If you want to give the user access to another file space or directory, you mustcreate another access rule.7. If you want to limit the user to specific files in the directory, type the name orpattern of the files on the server that the other user can access in the Filenamefield. You can make only one entry in the Filename field. It can either be asingle file name or a pattern which matches one or more files. You can use awildcard character as part of the pattern. Your entry must match files thathave been stored on the server.8. For the Java GUI: If you want to give access to all files that match the filename specification within the selected directory including its subdirectories,click Include subdirectories.192 IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive Clients Version 6.1: Installation and User’s Guide
