Hello list, Started using Kdar recently to back up my ~/home directory and a few other important things. Couple of questions. I read the Kdar manual a couple of times but not sure about this. I am backing up from one hard disk to another. Also won't work as user. Only root can access the backup directory. Did a differential backup tonight of ~/home. Seems to be very small (220 kb) I guess this means that the differential backup only saved things that were new? ( have added and deleted many files during this period though ) Kdar will NOT modify the original backup, right?? It will only create a new differential file based on the old one, right? Sooo....If I had to do a backup I would have to first reinstall the original backup and then follow up with the differential/incremental ?? If that is the way it works? Then does the differential backup then go back and delete the files which were deleted during the time between the original and differential backups ?? Just thought it might be good to know these things before I had to do an actual backup. Thanks for listening. Hope there is some expertise out there to straighten me out.
