I am running kopia cli on windows backing up large vdi files.
Kopia snap C:\virtualbox\vms
If I stop a backup (ctrl z) and start again with the same command the kopia starts scanning from the beginning.
This makes resuming backups more time consuming because it re reads the complete vdi files again instead of resuming.
I am using kopia 8.4
I guess checkpoints are created automatically
