Datasets can also be excluded from selection by these options:
* `--exclude-received`: Exclude datasets that have the origin of their `autobackup:backup-name` property as "received". This can avoid recursive replication between two backup partners.
* `--exclude-unchanged BYTES`: Exclude datasets that have less than BYTES data changed since any last snapshot. (Use with proxmox HA replication)

## Step 2: Snapshotting
In this step a snapshot is created on the datasets from step 1.

zfs-autobackup creates atomic snapshots per pool. e.g. it does one single `zfs snapshot ...` command that includes all the snaphots that need to be taken in a pool.

The snapshots are all created using a specific naming format. This includes a timestamp that zfs-autobackup uses to determine when a snapshot can be destroyed by the [Thinner](Thinner).
It is possible to change this format by using `--snapshot-format`. Other snapshots that do not match this format are normally ignored by zfs-autobackup. Use `--utc` to use UTC for timestamps.
