Congrats Emanual, on this new release.

excellent job guys!

Well done.

Just back from one’s hols. Will have a look in the morning.


I just installed 4.0.1 beta 2. Looking at the diagnostic log, synchronizer was running during installation. From this point on will the synchronizer from version 3 or 4 run? I am interested in running the newest version - hopefully with delete propagation to the synchronized drive.


Yes, there is delete propagation in version 4 of Comodo Backup, but you will have to redefine the sync jobs.
