The data structures that are backed up and restored through SnapVault depend on the primary system.
On systems running Data ONTAP, the qtree is the basic unit of SnapVault backup and restore.
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.
On open systems storage platforms, the directory is the basic unit of SnapVault backup. SnapVault backs up specified directories from the native system to specified qtrees in the SnapVault secondary system.
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.
