The Content Rule Details section also shows the included/excluded File Types, File extensions, and File Name Patterns. If you have selected the Ignore case sensitive file/folder name match for NFS shares option, the Content Rule Details section, displays it with a green tick.

📝 Note

​ The Content Rule Details cannot be edited from here. For more information see Edit Content Rule.

Specify Custom Content

Select the Specify Custom Content option to select the folders, file types, and file name patterns to be included in or excluded from the NAS share backups. You can save the selected folders, excluded subfolders, and included/excluded file types, extensions, and file patterns as a new content rule.

Backup All Folders

Select this option if you want to backup all files and folders, including hidden files and folders. The folders under Subfolder to exclude are excluded from backups.

Subfolder to exclude

Druva excludes a few folders from backup by default. For more information, see Folders excluded from NAS share backup. The subfolder exclusions apply whether you choose to backup all folders or specific folders. You can enter the absolute path of the subfolders that should be excluded from backups or enter the name of the directory or path you want to exclude from all the places in a share. Type the path of the subfolder, and then press Enter. The path gets added to the list below. To remove a subfolder from this list, click the cross icon next to the path. Consider the following rules and examples to understand subfolder exclusions:

The following are the rules for the subfolder exclusions:

📝 Note
​
​ For SMB share, the \ slash is also supported for exclusion logic.

Examples:
Suppose an NFS share vol0 has three folders:

Then, to exclude:

Backup Specific Folders

Select this option to backup specific folders on the NAS share. Type the relative path( relative to the root share directory) of the folder in the corresponding box and press Enter. You can also click Add <entered folder path> to add the folder. In folder paths, use backward slash ( \ ) for SMB shares and forward-slash ( / ) for NFS shares. You can add multiple folder paths.

Use the following formats while entering absolute paths:

NFS share

Specify File Exclusions or Inclusions
​
If this option isn’t selected all file types, file extensions, and file patterns in the folders selected under Backup Content are backed up.

Exclude the following files from backup

Exclude the specified file types, file extensions, and file patterns from the folders selected above.

Include only the following files in the backup

Include the specified file types, file extensions, and file patterns in the folders selected above.

File Types

Select file types to exclude/include

Select predefined file types that must be excluded from or included in the backup of folders specified under Specify Custom Content.

Add file extensions to exclude/include

This field displays the file extensions associated with the selected file types. You can enter custom extensions if you do not find your extensions under any predefined file types.

📝 Note
​
​ * extension or * .extension or .extension are unsupported formats.

File Name Patterns

Enter file name patterns that must be excluded from or included in the backup of folders specified under Backup Content. File patterns start with a * and can contain * *.string* or * .*string in the pattern string. Enter patterns like *.ext in the format ext in the file extension field under File Types.

📝 Note
​
​ The filename patterns File* and File*.extension are unsupported. For example, do not use a filename pattern like i mg* to include/exclude all files that start with img. Use *img* instead. Do not use a filename pattern like i mg*.jpg to include/exclude all files that end with the extension jpg. Enter the file extension jpg under File Types instead.

Ignore case sensitive file/folder name match for NFS shares

By default, this option is deselected. With this option deselected, the file and folder names entered in the Backup Specific Folders, Subfolder Exclusions, File extensions,and File Patterns fields are accepted as is, in whatever case you enter them. For NFS shares, this means that the entered text is case-sensitive. If this option is selected, Druva ignores the case of the files and folder names in these fields. For NFS shares, this means that the entered text becomes case-insensitive. Note: This option applies to NFS shares since file and folder names are case-insensitive in SMB shares.

Backup Proxy Pool

Select the backup proxy pool from the list that will be used for backup and restore of data from the NAS share.

Map the backup set to a pool that contains Windows proxies if you want to backup SMB shares or Linux proxies if you want to backup NFS shares. Druva displays the count of NAS proxies in the pool based on the Operating System type.

📝 Note
​You can only attach a single proxy pool to a backup set. Scheduled backups are triggered based on the proxy pool time zone.
