Page Synchronize methods

Synchronization method is a set of operations which HAS takes over the compared folder pairs during synchronization. On the page you can choose synchronization predefined method or customize your own method.

Synchronization mode defines a way how a synchronization would be made.

Sync mode Description
Sync per folder scan (real-time sync) HAS does synchronize a folder pair immediately after its folders are scanned. Then HAS does read subfolders of the folder pair and syncs them, etc. The main advantage of the synchronization mode is reducing of the memory usage. The mode allows to sync tens of millions of files at a time.
Folders pre-scanning HAS does scan all the folder pair contents, keeps it in the memory, and then starts a synchronization. Visual run requires to use this mode.

There are five predefined methods and a custom one:

Method Description
Mirror copy files from Left to Right Copies all files and empty folders from Left to Right and delete all single files and empty folders in the Right folders. So the Right folders will be made identical to the Left folders.
Mirror copy files from Right to Left Copies all files and empty folders from Right to Left and delete all single files and empty folders in the Left folders. So the Left folders will be made identical to the Right folders.
Copy files from Left to Right Copies all files and empty folders from Left to Right. So files and empty folders from the Left folders will be added/overwritten to the Right folders.
Copy files from Right to Left Copies all files and empty folders from Right to Left. So files and empty folders from the Right folders will be added/overwritten to the Left folders.
Update Left and Right (Make equal) Copies NEWER, SINGLE files and empty folders from Left and Right folders to the each other. So Left and Right folders will be equal and updated with most recent files and empty folders.
Custom This method allows you to manually set operations for file groups from the drop-down controls. Operations for empty folders will be enabled when you select this method.

Safe copying files (protect overwriting file until success file replication is done) - turn on this tick box to protect overwriting file. When this tick box is on HAS will copy a file to a temporary file, and when file replication is successfully done HAS will overwrite old file with new one.

Rename files instead of delete - turn on this tick box to protect deleting file. When this tick box is on HAS will rename a file instead of delete it. For example, HAS create the file My thesis.doc.(May 16, 2006 at 13-41-57).del instead of delete My thesis.doc.

Rename files instead of overwrite - turn on this tick box to protect overwriting file. When this tick box is on HAS will rename a file instead of overwrite it. For example, HAS create the file My thesis.doc.(May 16, 2006 at 13-41-57).owr instead of overwrite My thesis.doc.

Operations for empty folders are sets automatically for each predefined synchronization method.
If you want to customize operations for empty folders, set custom synchronization method.

Empty folders operations Description
