# Common snapshots and holds
![image](https://user-images.githubusercontent.com/1179017/165788773-b6e1301d-bc55-4b17-9ef0-a327e791b765.png)
If you're new to ZFS these terms can be quite confusing. Whats going on?
## Common snapshots
ZFS can do incremental transfers via snapshots. It can only do this from a snapshot that's common on both the target and source.
If there is no snapshot in common, the only way to continue is to destroy all the whole dataset (and all its snapshots) on the target and start from a full backup.
