what will Comodo backup

I am considering using Comodo backup. I have been using SyncToy for quite some time but there are so many glitches. One question, however: I want to backup individual files to an external drive. I don’t want to compress those files or save them as .img or any other file format other than what they were saved at. When I run a scan to backup those files, will Comodo backup copy only those files that have been changed or everything on the drive?


Sync with Comodo BackUp will copy only those files that changed.
There are some issues reported related to sync process, so we will fix them in the next release.
