Set Configuration Screen

The configuration screen shown below enables you to define a set of files to be backed up. It also allows you to configure how files that already exist in the destination directory should be dealt with. For example you may want to keep old versions of a file, in this case you can define how and where these older versions should be kept.



The various options on the screen are described below :-

Set Name :- This defines the name of the set. This name is displayed on the main Configuration Screen The set name can only be made up of alphabetic (a-z,A-Z) and numeric (0-9) characters as well as spaces.

Source Directory :- This is the directory that you want to be backed up. Click on the "Browse" button then use the windows explorer type dialog box to navigate to the directory you want to select, then click the Open button.

Destination Directory :- This is the directory were the source files specied above will be copied to. Click on the "Browse" button then use the windows explorer type dialog box to navigate to the directory you want to select, then click the Open button.

Filter :- If you only want to backup a single file or a specific type of file then the filter can be used to define these files. For example if you are only want to backup word documents in the "My Documents" folder then you can specify a filter of *.doc. If you would also like to backup a particular file you can specify the file name in the filter, e.g. :- accounts.xls;*.doc This filter would backup all word documents and the file accounts.xls. Filters should be separated by ; (semi-colon). Any number of filters can be used.

Include sub-directories This option allows you to include all the sub-directories under the main directory selected in the "Source Directory or file" described above.

Copy Criteria. If a file does not exist in the destination directory it will always be copied unless you choose the archive option and the archive bit is not set. These options are used to determine if a file should be copied when a file already exists in the destination directory. Three options are available :-

1. File Date & Time. This option should be used if you want to copy newer versions of the file over an older file, i.e. the file in the source directory has been modified more recently than the file in the destination directory. This is useful when files are frequently updated.
   
2. Archive Bit. All files have an archive bit (or flag). This flag is cleared by a backup program such as Clone when the file has been successfully backed up. The flag is set the next time the file is updated, thus allowing Clone to determine if the file needs to be backed up again. Using this option will have a similar outcome to the Date & Time option described above. If any other backup programs are used on your PC then use this option with caution as other programs may clear the archive flag.
   
3. File Size This option will only copy a file if the source file is a different size to the destination file. This option does not use the date of the file so could in theory copy an older version of a file over a newer version if the file sizes are different. Use with caution

1. 1 way source --> destination. This copies new / updated files from the source directory to the destination directory. This is the default option.
   
2. 2 way source <--> destination. This copies new / updated files from the source directory to the destination directory and also copies new / updated files from the destination directory to the source. This would be useful for synchronising a documents directory on a desktop machine with a documents directory on a laptop
   
3. 1 way destination --> source This copies new / updated files from the destination directory to the source directory. This might be useful for restoring your files in the source directory after a system crash.

• Overwrite files in destination directory. If this option is chosen then files in the destination directory will be overwritten by files in the source directory (if the copy options determine a file needs to be copied). If this option is unchecked, files will not be overwritten and any subsequent changes to the source file will not be backed up. Uncheck this option with caution.
  
• Keep a copy of existing file. This option allows you to keep the existing file that is in the destination directory. This is achieved by 2 techniques. Either the file is moved to a defined sub-directory of the destination directory (archive in the screen shot above) or the filename is appended with a sequence or date-time stamp. The sub directory and the file name append options can be used together if required.
  
• Move to sub-directory. This option will move old files to the specified sub directory. This can be used to store a historical record of changes to a file each time it is copied by Clone. This can be useful where you may need to go back to a previous version of a file.
  
• Keep original file name. This keeps the original file name and does not append a date or sequence number to the file name. If you choose the "Keep copy of existing file" option above and this option you also have to enable the move to sub directory option.
  
• Append file name with sequence number. This option appends the file name with a sequence number, eg. cv.doc becomes cv.doc.1 when a new version of cv.doc is discovered the older version will be renamed to cv.doc.1 before the new file is copied. This allows you to keep a history of a file and will allow you to got back to an older version of a file if you make a major blunder in the new file.
  
• Append file name with date. This option appends the file name with the date and time, eg. cv.doc becomes cv.doc.03102002-213928 when a new version of cv.doc is discovered the older version will be renamed to cv.doc.03102002-213928 before the new file is copied. This allows you to keep a history of a file and will allow you to got back to an older version of a file if you make a major blunder in the new file. The example shown here was copied on 03/10/2002 21:39:28 hrs.
  
• Delete files removed from source directory. If a file exists in the destination directory and it not present in the source directory (for example it has been deleted) this option will remove the file from the destination directory. This option is only applicable to one way synchronisations. Use with caution!
