Allway Sync

Pros: Copies almost anything, no matter if the file is active.
Great logging capabilities.
Service doesn't crash.

Cons: It's pretty messy when it comes to finding file sync conflicts. Combined with online services like Dropbox, the file share balloons quickly.

Overall: The product fills the need of rsync or scp in non-Linux environments and can aid when mounting a share or online service is prohibitive. As the environment grows, other products mostly phase it out.

Used this product to synchronize multiple file servers in different office locations.

Behind the scenes, it's solid for Hyper-V virtual machine copies.

It's great for accountants who maintain a multitude of QuickBooks local databases.

I've used it to keep a file server in sync with Dropbox online shares and it's reliable in determining what is the most recent file/folder version.

The app always runs as scheduled and has never stopped mid job.

Pros: I was a big fan of using robocopy but after facing some problem like copying files that are in use or copying changes only in a simple way, a friend recommend me Allway Sync and gs richcopy 360, honestly, both are amazing in this field

Cons: Till now I did not found any cons that I should highlight because it was needed in a job and it was successful .

Overall: Copying files that are in use is not simple and needs powerful tools to handle this issue, also copying the changed data

Pros: When we need to transfer large-sized data from server to another via robocopy and we faced problems like speed and long path name error, a friend recommended us Allway Sync and GS RichCopy 360.

Cons: For Allway Sync Memory errors on large drive or folder synching (increasing paging memory doesn't help). Exclusions and many other features are more difficult to use than they should be. Licensing cost too much for the quality of the program.

Overall: Allway Sync and GS RichCopy360 were amazing with transferring large-sized data, both are affordable.

Pros: Helps me keep my files synced across several computers. It's easy to setup. I am using several different sync profiles, separate for work files, personal pictures, etc. Using the Pro version, single low payment for life.

Cons: Sometimes it behaves a bit too carefully, as if trying to second-guess if I really mean it with some deletions, which it refuses to propagate, and I have to correct it manually.

Overall: Very happy. File sync with my backup drive is a way better idea than "black box" backups. And Allway Sync makes it easy.
