The data structures that are backed up and restored through SnapVault depend on the primary system.
SnapVault backs up specified qtrees on the primary system to associated qtrees on the SnapVault secondary system. If necessary, data is restored from the secondary qtrees back to their associated primary qtrees.
If necessary SnapVault can restore an entire directory or a specified file to the open systems platform.
The destination system uses a slightly more disk space and directories than the source system.
The following illustration shows the backup of qtrees and directories on different systems to a single secondary volume:
