| # DESCRIPTION: |
| # |
| # Directory structure of snapshots reflects filesystem structure. |
| # |
| # STRATEGY: |
| # |
| # This test makes sure that the directory structure of snapshots is |
| # a proper reflection of the filesystem the snapshot was taken of. |
| # |
| # 1. Create a simple directory structure of files and directories |
| # 2. Take a snapshot of the filesystem |
| # 3. Modify original filesystem |
| # 4. Walk down the snapshot directory structure verifying it |
| # checking with both absolute and relative paths |
| # |
