Last week, Amazon Web Services (AWS) announced that they now support crash-consistent snapshots of multiple EBS volumes: https://aws.amazon.com/blogs/storage/taking-crash-consistent-snapshots-across-multiple-amazon-ebs-volumes-on-an-amazon-ec2-instance/. This is a big deal, especially for database workloads, as this makes it much easier to take a consistent snapshot of all volumes (RAID, data + log, file groups, etc.) involved in a single database instance. This makes it much easier to create safe disaster recovery solutions for databases running on EC2. Big step forward for AWS!
