Guidelines for exclusion filters for file systems

Review the following guidelines for exclusion filters.

Excluding by file size

When viewing the size of a file on a remote file system, only the value in bytes is precise. The calculations used to round bytes to a different measurement are specific to each vendor and operating system. It is not recommended to use a non-byte measurement with the Equal to filter.

CAUTION: The calculations that are used in the following examples use base 2, since all operating systems use base 2. However, the PowerProtect Data Manager Appliance user interface performs calculations using base 10. If you are following these examples and providing a value in megabytes, convert the values that are documented from base 2 to base 10. Otherwise, use only bytes to avoid any chance of error.

For example, an asset host could indicate the following information for the size of a file:

Size: 750 MB (786,652,672 bytes)

If you use an exclusion filter of Equal to with a value of 750 MB, the rounding of bytes to megabytes almost certainly results in the file not being excluded.

Examples of exclusion filters to exclude this file by size include the following:

Equal to with a value of 786,652,672 bytes
Greater than or Equal to with a value of 749 MB or 785,000,000 bytes
Less than or Equal to with a value of 751 MB or 787,000,000 bytes

Using wildcards

Supported wildcards include an asterisk (*) to represent zero or more characters and a question mark (?) to represent zero or one character.

NOTE: Be careful when using the wildcard *. Depending on the wildcard location, you can match folders whose name matches the filter pattern, even when the names of files do not. For example, *\log*.txt also excludes files with the .txt extension in a folder whose name starts with log, even if the names of the files do not start with log.

Unsupported characters in file and path names

File and path names that contain a comma () cannot be directly specified in a filter. To exclude such a file or path, use a wildcard.

Excluding by file type

The File Type filter enables you to exclude files and folders that use a file extension.

You can specify a single extension or multiple file extensions. Separate multiple entries with a comma and do not add a space between entries. You can also specify related extensions by using wildcards. For example, *.doc? matches both .doc files and .docx files.

Excluding by type and path

You can combine extension and path to exclude all files of a particular type without respect to the file location.

For example *\log*.txt matches all text files (.txt) where the file name starts with log, at any path.

You can also exclude all files of a particular type from a specific path or multiple paths that are separated by commas. For example,

Specifying C:\abc\*.txt excludes all the text files in the folder C:\abc.
Specifying C:\folder1\*.txt, D:\folder2\*.doc excludes all the text files in the C:\folder1 and the doc files in the D:\folder2 folders.

NOTE:All the matching files under subfolders of the specified path are recursively excluded.

You can combine these guidelines to exclude all files that match a specific name pattern under a particular path. For example, C:\folder\log*.txt.

Excluding by file path

The Folder Path filter enables you to exclude files and folders in a specific path.

You can specify an absolute or relative path.

The following table provides examples for excluding files and folders using absolute and relative paths.

Table 1. Absolute and relative path examplesAbsolute and relative path examples
Type of path	Folder	File
Absolute	F:\folder1\folder2\* In this example, the filter excludes all files and folders under F:\folder1\folder2.	F:\folder1\folder2\sample.txt In this example, the filter excludes the sample.txt file under F:\folder1\folder2.
Relative	\folder1\folder2\	*\folder1\folder2\sample.log
	In this example, the filter excludes all files and folders under any volume with the hierarchy folder1\folder2.	In this example, the filter excludes all sample.log files under any volume with the hierarchy folder1\folder2.
	D:\\folder1\folder2\	D:\*\folder1\folder2\sample.log
	In this example, the filter excludes all files and folders under any folder in D: with the hierarchy folder1\folder2.	In this example, the filter excludes all sample.log files under any folder in D: with the hierarchy folder1\folder2.

Excluding multiple paths

Use commas to separate multiple paths and do not add a space between entries. For example, to exclude the folder C:\Program Files, the folder C:\Program Files (X86), and the folder C:\Perflogs, use the Folder Path filter C:\Program Files,C:\Program Files (X86),C:\Perflogs. Do not enclose each path in quotation marks.
