Always copy the files, even if timestamp unchanged
The program normally copies files only if they don't exist on the other side yet, or if the "Last Modified" timestamp has changed. However, some programs don't update the files' timestamps even if their content changes. This checkmark causes all files to be copied even if apparently unchanged.

Binary Comparison Of Existing Files While Building the File List
Use this setting to verify that the file contents of existing files is 100% identical on both sides. Only files which would normally be considered identical by looking at the file size and timestamp will be verified. If the binary comparison shows that the files are different, they will be marked for copying in the profile's main copying direction. If the profile has both directions checked, then the Synchronization Preview will show such files with the word CONFLICT and it will not do any copying by default. You can then set the desired copying direction in the Synchronization Preview.

This checkmark should not usually be used for jobs that run regularly, because it causes a lot of disk usage or network traffic. Moreover, this checkmark does not cause newly copied files to be verified. To verify files after copying, use the checkmark Verify copied files on the Files tab sheet.

However, in conjunction with the new Remember Results feature, it is actually feasible to leave this option checked for repeated runs. Syncovery will remember which files have verified successfully, and not repeat the Binary Comparison for them in future runs. This also makes it possible to interrupt jobs during the comparison phase. When the job is started again, it will skip the binary comparisons that were previously successful.

Use Remotely Generated MD5 Checksums For Comparisons
This checkmark will make the program use MD5 checksums for verification rather than a complete binary verification. To make this work, the Syncovery Remote Service must be running on the other end. Do not choose this checkmark if you want MD5s to be used with some cloud services that support it. That will be done automatically.

Compare / Mirror: Attributes
This setting causes the program to compare file attributes, such as Read-Only, Hidden, and Archive. When files are identical except for the file attribute, the file is not copied again. Only the attribute is changed on the destination side.

Folder Timestamps
If you are synchronizing in one direction, you may want the folders on the destination to have the same timestamps as on the source side. Newly created folders are automatically adjusted in this way, but existing folders may deviate. To have existing folders adjusted on the destination side, use this checkbox.


Enforce Hard Links For Existing Files
This checkmark can be chosen to update the hard-link status for existing files so that it matches the source side.

Adjust Case Spelling At Destination
Filenames on Windows are not case-sensitive. This means that myfile.doc would be the same file as MyFile.DOC. However, you may want your files to look identical. So, if you have a folder where some spellings are different in terms of case, then you may use this setting in order to adjust the case at the destination. You can only use this option when the profile has only one main copying direction.

Strict Case Sensitive Mode
If you are syncing two file systems that are case sensitive and allow duplicate file or folder names that only differ in their case spelling, then you can choose this option to enable Syncovery to sync correctly, and to allow these duplicate names. On Windows, this is not possible with local or UNC paths. It can only be used with FTP, SFTP, and some other case-sensitive protocols (such as the Google Drive API).

Verify Sync Statistics After Completion
This checkmark should be used only rarely! It will cause the left and right folder trees to be scanned completely again after the synchronization has completed. This verification stage will end in detailed statistics which are used to verify that the backup or mirror is complete. Any files or folders that still don't exist on both sides are listed.
