Reference documentation and code samples for the AlloyDB v1 API class Backup.Types.QuantityBasedExpiry.
A backup's position in a quantity-based retention queue, of backups with
the same source cluster and type, with length, retention, specified by the
backup's retention policy.
Once the position is greater than the retention, the backup is eligible to
be garbage collected.
Example: 5 backups from the same source cluster and type with a
quantity-based retention of 3 and denoted by backup_id (position,
retention).
Output only. The backup's position among its backups with the same source
cluster and type, by descending chronological order create time(i.e.
newest first).
