On the Filters page of the Options window (accessible from the Tools, Options menu item) you can define filters to be used in the application.
Accessible via Tools->Options->Filters
General
Filter name
Type a name for the filter to be recognized when you want to use it later.
Show filter in the New Backup Wizard
If checked, the current filter can be selected from the Filters list in New Backup Wizard.
File name
Enabling this will allow defining filters based on file name pattern.
Press Add and select an existing file extension from the Filter combo (*.doc, *.pdf, *.zip etc.). If the extension does not exist in the combo, just type it in and press OK. You can use the Edit or Delete buttons to modify/remove the file name filters defined.
File name patterns can include:
| • | * - it matches one or more letters. For example a*.doc matches all files that start with a and have .doc extension |
| • | ? - it matches only one letter. For example a*.do? matches all files that start with a and have any extension composed of three letters, the first two being do |
Folder name
Enabling this will allow defining filters based on folder name pattern.
Enter the directory name that you want to filter in the following format: *\directory_name\* . Backup4all will apply the filter to all the directories that are called directory_name. If you want to apply the filter to directories containing a specific word, you must enter it in the following format *\*keyword*\*. Now Backup4all will apply the filter to all the directories that have the word keyword in their names. You can use the Edit or Delete buttons to modify/remove the folder name filters defined.
File attributes
This section allows the user to specify file filters depending on the file attributes. To enable the filter options in this section you have to check the Filter by attributes option.
There is a list of quick sets to choose for predefined filter criteria:
| • | None - if this is selected all the file attributes check boxes are unchecked |
| • | Custom - this is the default option and allows you to check whatever attributes you want |
| • | FAT attributes - if this is selected, a set of File Allocation Table attributes will be used for file filtering |
| • | NTFS attributes - if this is selected, a set of NTFS (New Technology File System) attributes will be used for filtering. Note that these attributes are available only on Windows 2000, Windows XP, Windows Server 2003 and Windows Vista. |
File attributes available for file filters:
| • | Read-Only - if checked files with read-only attribute will be selected |
| • | Archived - if checked files with archived attribute will be selected |
| • | Hidden - if checked files with hidden attribute will be selected |
| • | System - if checked files with system attribute will be selected |
| • | Compressed (only NTFS) - if checked files with compressed attribute will be selected |
| • | Temporary (only NTFS) - if checked files with temporary attribute will be selected |
| • | Encrypted (only NTFS) - if checked files with encrypted attribute will be selected |
| • | Not indexed (only NTFS) - if checked files with "not indexed" attribute will be selected |
| • | Offline (only NTFS) - if checked files with offline attribute will be selected |
| • | Reparse point (only NTFS) - if checked files with reparse point attribute will be selected |
| • | Sparse file (only NTFS) - if checked files with sparse file attribute will be selected |
For example, if you want to include files with read-only and archived attributes set, you have to check both attributes checkboxes in a single restriction. If you want to include files with read-only or archived attributes set, you have to make two separate restrictions: one for read-only and another for archived.
File dates
This section allows the user to build restrictions based on file dates and times. To enable options in this section, check the Filter by date option.
Filters in this section can be applied by selecting one of the available date filters:
| • | date accessed |
| • | date and time accessed |
| • | date modified |
| • | date and time modified |
| • | date created |
| • | date and time created |
You can compare these dates and times with a fixed date or a relative date: today, yesterday, one week ago or one month ago.
Comparison operators available:
| • | < > date (and time) not equal to fixed or relative date |
| • | < = date (and time) less than or equal to fixed or relative date |
| • | > = date (and time) greater than or equal to fixed or relative date |
| • | < date (and time) less than fixed or relative date |
| • | > date (and time) greater than fixed or relative date |
| • | in interval - date (and time) in a particular time interval between the Start date and End date |
File size
This section provides the possibility to build restrictions based on the file size. To enable the options in this section, check the Filter by size option. You can enter a file size in the Size field and select a measurement Unit. The filter will compare the file size on disk with the size you enter using the comparison filters you selected:
| • | < > file size on disk not equal to the value in the Size field |
| • | < = file size on disk less than or equal to the value in the Size field |
| • | > = file size on disk greater than or equal to the value in the Size field |
| • | < file size on disk less than the value in the Size field |
| • | > file size on disk greater than the value in the Size field |
Example
Suppose you want to backup (or restore) all .pdf files accessed in the last month and all .doc files modified in the last week, but you don't want to backup (or restore) system or hidden files.
Here are the steps to define this filter starting from the default filter:
1) Add a new restriction in the include filter: enable File name, add *.pdf file pattern and set date accessed to be greater than or equal to fixed date one month ago; click OK
2) Add a new restriction: add *.doc file pattern and set date and time modified to be greater than or equal to fixed date one week ago; click OK
3) Add a new restriction: enable File attributes and the System checkbox, then click OK
4) Add a new restriction: enable File attributes and the Hidden checkbox, then click OK
5) For the last two restrictions, check the Use as exclude filter boxes.
