• Rules for Copying Files and Folders
• Rules for Deleting Files and Folders
• Rules for Overwriting Files

Copy missing files and folders

This option causes all files and folders not present in the directory on the other side to be copied.

Don't search folders (NTFS junction points) that point to the contents of another folder

NTFS junction points are empty folders that point to the contents of another folder. This option enables you to prevent these folders from being searched and processed. This option is activated by default. When activating this option you should check first that no loops are created by the junction points and no data items are processed twice.

Store source file as compressed ZIP file at destination

This causes a source file being copied to be stored as a compressed ZIP file at the destination.
Example: Data.doc -> Data.doc.zip

Compression

This option enables you to specify the compression to be used for the files being backed up. The following settings are possible:

• None
• Fast
• Normal (default setting)
• Maximum

The higher the compression, the longer it takes for the ZIP file to be created. The None option causes items to be zipped without being compressed.

Compression method

The following settings are possible:

• Deflate (info)
• Deflate64 (info)
• BWT (info)
• LZMA (info)

Deflate is the default compression method of the general ZIP format supported by many other programs. In comparison to Deflate, Deflate64 and BWT enable a higher degree of compression to be achieved, however they aren't supported by all programs.

Encryption

This option enables you to password-protect the ZIP file against unauthorized access. The following encryption methods are available:

• Standard Zip 2.0
• AES 256-bit (info)

Using the AES encryption method is advisable as it provides a much higher degree of security than conventional Zip 2.0 encryption.

Move source files to destination folder

This causes the source files being copied to be moved to the destination folder. You can also specify that empty source folders are to be deleted:

• Delete all source folders that are empty after being moved
• Delete all source folders that were empty prior to being moved

Copy only files with the 'Archive' attribute

This option causes only files possessing the 'Archive' file attribute to be copied. All files without the 'Archive' attribute are automatically filtered.

Transfer access permissions of files and folders

This option enables you to transfer the access permissions of files and folders to their destination counterparts. To this end, the partitioning of the source and destination data items has to be done using NTFS. When the only when creating and copying files option is activated, permissions are not transferred unless a file/folder is copied to the destination.

• If you want to transfer access permissions on the local machine, you have to be logged on as the administrator and possess the requisite read and write permissions for the source and destination items.
• If you want to transfer access permissions between two computers in the network the computers have to be registered in the same domain. You also have to be logged on as the domain administrator and possess the requisite read and write permissions for the source and destination items.

This option causes all files and/or folders not present at the source to be deleted at the destination. You can also specify which data items are to be deleted:

• Files + Folders
• Files
• Folders

This causes all files and/or folders which are filtered at source to be deleted at the destination. You can also specify which data items are to be deleted:

• Files + Folders
• Files
• Folders

This option specifies when a file is to be overwritten by another file of the same name. The following settings are possible:

1. Never overwrite
2. Always overwrite
3. Overwrite file if modified date/time of file being copied is more recent
4. Overwrite file if modified date/time of both files is different
5. Overwrite file if size of both files is different
6. Overwrite file if the contents of both files are different

For other settings for comparing the contents of two files, see File Options – Content Comparison Method.

The following additional rules are possible when applying main rules 3 and 4:

• or the contents of the files are different
• and the contents of the files are different
• or size of files is different
• and size of files is different

For other settings for comparing the contents of two files, see File Options – Content Comparison Method.

This option enables an exact time differential between the modified date/time of the source and destination file to be ignored, thus preventing the source file from being copied. The time differential can be specified in hours, minutes and seconds. This option may be useful after a switchover between standard and daylight saving time, as the source and destination files may exhibit a time differential of one hour.

This option enables a time differential of up to 24 hours between the modified date/time of the source and destination file to be ignored, thus preventing the source file from being copied. The time differential can be specified in hours, minutes and seconds. This may be useful when running copy operations between NTFS and FAT partitions, as the modified date/time of the two files may exhibit a differential of several seconds after copying.
