Creates a backup for an existing table.
Each time you create an On-Demand Backup, the entire table data is backed
up. There is no limit to the number of on-demand backups that can be
taken.
When you create an On-Demand Backup, a time marker of the request is
cataloged, and the backup is created asynchronously, by applying all
changes until the time of the request to the last full table snapshot.
Backup requests are processed instantaneously and become available for
restore within minutes.
You can call CreateBackup
at a maximum rate of 50 times per
second.
All backups in DynamoDB work without consuming any provisioned throughput
on the table.
If you submit a backup request on 2018-12-14 at 14:25:00, the backup is
guaranteed to contain all data committed to the table up to 14:24:00, and
data committed after 14:26:00 will not be. The backup may or may not
contain data modifications made between 14:24:00 and 14:26:00. On-Demand
Backup does not support causal consistency.
Along with data, the following are also included on the backups:
-
Global secondary indexes (GSIs)
-
Local secondary indexes (LSIs)
-
Streams
-
Provisioned read and write capacity
