Use this page for advanced NAS filtering patterns, including snapshot handling and network path behavior.
NAS wildcard patterns
| Pattern |
Description |
Example |
Behavior |
** |
Matches directory levels across NAS paths |
/vol/data/**/cache/* |
Matches folders at any level |
*** |
Matches full directory tree |
/share/*** |
Filters entire share recursively |
* |
Matches file patterns |
*.log |
Filters files across NAS |
NAS path behavior
| Scenario |
Behavior |
| Match full NAS export |
Uses recursive directory matching |
| Match nested directories |
Uses multi-level wildcard matching |
| Match large directory trees |
Use *** for full traversal |
| Cross-protocol matching |
Works across NFS and CIFS paths |
snapshot filtering behavior
| Scenario |
Pattern |
Behavior |
| NetApp snapshot directories |
**\.snapshot\*** |
Excluded automatically |
| Generic snapshot folders |
**\~snapshot\*** |
Excluded automatically |
| Legacy snapshot folders |
**\~SNAPSHT\*** |
Excluded automatically |
| Override snapshot exclusion |
<BIF,-Snapshots> |
Includes snapshot directories |
NAS-specific advanced scenarios
| Scenario |
Behavior |
| Filter entire share efficiently |
Use full recursive patterns |
| Handle snapshot-heavy environments |
Keep default exclusions |
| Avoid duplicate backups |
Do not include snapshot paths unless required |
| Optimize large NAS backups |
Use targeted directory filters |
NAS filtering rules
| Rule |
Behavior |

Excluded by default |
| Pattern matching |
Applies across all directory levels |
| Protocol handling |
