Ok, i undestand. Thanks. :)

Its correctly failing because the checkpoint information about the disks is inconsistent ( the freshly added disk does not have an bitmap tied to the (prior) checkpoint)
Thats okey. There is currently no logic that attempts to check wether if an virtual machine amount of disks was altered between full and incremental backup. That would be an enhancement, as it stands. Currently the user at least notices theres something wrong.
Also, falling back to a full backup would mean backup needs to go to a new directory, as the current backup folder used already includes an full backup (complete new backup chain must be started to a fresh, empty directory), and following incremental backups must be changed to this target directory then too. Its not an easy fix and there all kinds of scenarios i could imagine this will result in confusing situations.
I dont think ill implement this, ill leave it to the users sane behavior to know a full backup should be done next if
hes altering the virtual machine configuration in such ways, or script around this using pre/post scripting.
Also i dont know if the restore utility could handle this correctly without changes and the feature would become even more interesting in transient virtual machine (clustered) environments where re-defining the checkpoints is mandatory to continue backup chains.
