| 7 | snapshot implementation. Many common filesystems have native |
|---|
| 8 | support for this. |
|---|
| 9 | </p><p>Filesystem snapshots must be mounted on |
|---|
| 10 | specially named directories in order to be recognized by |
|---|
| 11 | <span><strong class="command">vfs_shadow_copy</strong></span>. The snapshot mount points must |
|---|
| 12 | be immediate children of a the directory being shared.</p><p>The snapshot naming convention is @GMT-YYYY.MM.DD-hh.mm.ss, |
|---|
| 13 | where: |

| 14 | </p><div class="itemizedlist"><ul type="disc"><li><p><span><strong class="command">YYYY</strong></span> is the 4 digit year</p></li><li><p><span><strong class="command">MM</strong></span> is the 2 digit month</p></li><li><p><span><strong class="command">DD</strong></span> is the 2 digit day</p></li><li><p><span><strong class="command">hh</strong></span> is the 2 digit hour</p></li><li><p><span><strong class="command">mm</strong></span> is the 2 digit minute</p></li><li><p><span><strong class="command">ss</strong></span> is the 2 digit second.</p></li></ul></div><p> |

| 27 | such. Additionally, if you need version control, implement a |
