I have perhaps twice had an error in the log file, out of thousands of runs. It is NOT my only means of backup for that reason. SyncBackFree may have defects.I've just never encountered them. Obviously, a profile can have disastrous results if you think it's going to do A and it does B.like deleting from the source or not keeping versions if you don't use mirroring. You should always experiment with a new profile. If that's what it means and that's what you want, use it. 'Backup'? I don't know what that is.maybe it means if dog.jpg is deleted from source it is kept on target? I don't use it and have no interest in it. Mirror versus Backup: Mirror is a replica if dog.jpg is deleted from source, it is deleted from target. It will drive you crazy if you can't just accept it as Windows being Windows. I've never been unable to find a file on the target drive that I expected to find there.Īnd.Windows File Explorer has it's own weird peculiarities re file counts, file sizes, space used, space remaining, etc. My 'all data' SyncBackFree backup that I ran an hour ago has 99737 files. Right now, my data drive supposedly has 99732 files. Similarly, applications like Macrium Reflect don't back up ALL system files. SyncBackFree by design does NOT copy all files. I'm not sure that anything needs to be resolved. Re difference between file count on source versus destination:

Does it have anything useful to you not found in Free? I've never even given it a trial run.

I see that you are using the Pro version now.
