degrades by up to 10%. This can result in a transient I/O speed decrease. We recommend
that you create automatic snapshots during off-peak hours.

days. The following options are available:

- Always Keep: If the maximum number of automatic snapshots for a disk is reached, the earliest
snapshot created based on the automatic snapshot policy is deleted when a new snapshot
is created.

Select existing tag keys and values, or enter new tag keys and values. Automatic snapshots
created based on the automatic snapshot policy are bound with these tags.

that are created based on the automatic snapshot policy are copied to the destination

After you select Enabled, you must continue to set the Destination Region and Retention Time of Snapshot Copies parameters.
For information about regions that support snapshot copying and billing rules of snapshot
