It's always a good idea to backup your important data to other drives or locations so that you may restore the data in case something bad happens.
Manually backing up folders can become a chore, but using a folder sync solution may make the job easier, especially if you want files to be synced regularly or need to access files on different devices.
Echosync is a freeware folder synchronization software for Windows. The application comes in a portable archive. Extract it to a folder and run Echosync.exe to start the program. Or, run EchosyncLauncher.exe to run the application with administrator privileges. This allows you to sync files which are locked by another process. The program prompts you to create a new Sync profile. Give it a name, select the source and destination folders, and a description (optional).
Once you have added the profile, you may start using the Echosync interface. It has a two pane design. The profile which you created is displayed in the top pane, called Sync Profiles. It lists every task along with information, status, and the last sync time. To add a new task in Echosync, click on the "New" button in the top right corner. The "Delete" option removes the selected profile. The pane below, named "Result Comparison", displays the result of the synchronization process, which we'll get to in a bit.
There are a few options on the bottom of the Echosync window. These allow you to select the synchronization options. The first option can be toggled to sync only the files that were moved or renamed. The second option syncs deleted items. The third setting may be used for syncing files which were modified (edited) in the source folder. In case you want to jump back to a previous version, use the fourth option which syncs the older files from the source directory. The final option syncs new items, i.e. files that aren't present in one of the folders. You can tell from these options, that the synchronization is a two-way process.
Hit the Compare button to preview the results without synchronizing the folders. Echosync will scan the two folders to detect the changes. The Result Comparison window displays the scan results.
It displays the folder name (destination or source) and path, along with the list of files that were detected. The 2nd column, Process, indicates the action that Echosync is set to take. The action depends on the options you selected in the toolbar.
For e.g. "New file to copy" means that a file is missing in one of the folders. "Missing file to delete" indicates that a file which was deleted from one directory will be copied). "Newer file to copy" tells you that a file has been modified, and the new version will be synced. The "Older file to copy" process means an old version was detected in the source folder.
The other columns display the size of the file and the timestamp. Right-click on a file in the results to open its folder in Windows Explorer. The toolbar at the bottom also displays the number of files detected and their file size (on a per-option basis).
When you're happy with the comparison, click on the Sync button. Echosync will process the changes as required. The Results pane displays the Status of each file, if it reads "OK" the synchronization process was successful.
Right-click on a sync profile to manage it or to view the synchronization log. If you right-click on an empty space in the top pane, you can set the post-sync action (Do nothing, shut down, hibernate or exit Echosync). You may also use this menu to switch the interface to a Dark theme, change languages. The program doesn't have a scheduler, the shortcut is merely to open Windows' Task Scheduler, should you want to configure auto-synchronization on a regular basis.
Echosync is made by Luminescence Software, the developer of Metatogger. You'll need .NET Framework 4.7.2 or higher to run the program. It works on Windows 7 and above.
The only issue with the program is that it includes sub-folders from the source folder in the synchronization process. To exclude it, you'll need to edit the profile's XML file.
Echosync is user-friendly and does what it's supposed to without a hassle. There's no limitation to the file type that you can sync, so you can use it to backup your photos, videos, documents, music, etc.
