In SnapVault backups, what is the basic unit of the backup destination?

• A. The file is the basic unit for SnapVault backup destination.
• B. The qtree is the basic unit for SnapVault backup destination.
• C. The volume is the basic unit of SnapVault backup destination.
• D. The directory is the basic unit for SnapVault backup destination.

Answer: (B)

The basic unit is a qtree. SnapVault works by backing up each qtree on the source to a matching qtree on the destination, so the destination’s data is organized per qtree. A volume may contain multiple qtrees, but that unit of backup and restore granularity is the qtree, not the entire volume, a file, or a directory. This per-qtree approach lets backups be managed and restored at finer granularity while keeping the destination structure aligned with the source.
