I have two machines with Veeam Endpont Backup Beta installed. The first machine has a 5TB USB 3.0 external drive connected to it and I am doing an Entire Computer backup to the USB drive. The first backup was a full backup as I expected which was about 500GB. Each day after that the backups have been between 3GB and 5GB for the past days as expected for the changed blocks. The problem is on the second computer where I tried something different. I created a volume on my SAN and setup the iSCSI connector on the PC and connected to the volume. I then formatted the volume and assigned a drive letter to it. When I tried to configure the backup for the Entire Computer, it would not let me and gave me a warning that I could not do the Entire Computer backup to a local drive. So what I did was created a share on the volume and then setup the destination to be mypc\share and it allowed me to do the Entire Computer backup to the share. The first backup was a full backup as expected which was about 158GB. The problem with this computer is that each day after that, it is doing another full backup and the size increase about 3GB each day. So the second day, the backup size was 164Gb, the third was 167GB, the fourth was 171GB and the fifth was 174GB. I assume this is unexpected behavior.
