In UNIX Open Systems SnapVault backups, which object is NOT a valid data set component?

• A. file
• B. qtree
• C. directory
• D. entire client

Answer: (B)

In UNIX Open Systems SnapVault backups, a data set is built from units that can be backed up: individual files, directories (the whole directory tree), or the entire client. A qtree is a 7-Mode construct used to partition a volume’s namespace, but it isn’t exposed as a separate data set component for this backup type. So, you can back up specific files, or a whole directory, or the entire client, but you can’t select a qtree as its own data set component. If you need to cover a qtree’s data, you’d include the files or the directory within that qtree, or back up the entire client, rather than using qtree as a distinct data set component.
