Continuous and incremental backups across regions.Continuous and incremental backups to S3.RedShift provides continuous/incremental backups: ![]() A replica on compute nodes (within the cluster).RedShift always keeps three copies of your data: Redshift replicates your data within your data warehouse cluster and continuously backs up your data to Amazon S3. Only available in one AZ but you can restore snapshots into another AZ.Īlternatively, you can run data warehouse clusters in multiple AZ’s by loading data into two Amazon Redshift data warehouse clusters in separate AZs from the same set of Amazon S3 input files. RedShift uses replication and continuous backups to enhance availability and improve durability and can automatically recover from component and node failures. Parallel/distributed execution of all queries, loads, backups, restores, resizes.Īmazon RedShift Spectrum is a feature of Amazon Redshift that enables you to run queries against exabytes of unstructured data in Amazon S3, with no loading or ETL required.Stores data and performs queries and computations. ![]() ![]()
