Amazon S3 vs Commvault Complete Backup & Recovery

• Highly available and redundant; we do not worry about the service having downtime
• Simple usage from multiple different frameworks using Amazon's SDKs, or roll your own
• A large number of bucket policies and security adjustments to tailor usage to customer needs
• Regional support for storing assets in particular locations around the world

• Commvault is the Swiss Army knife for data protection in an Enterprise environment. You name the environment and Commvvault has something to protect it. Very helpful in this on-prem/off-prem world that is developing into a DevOps world.
• Improves our Disaster Recovery
• Starting to utilize for data migration for VMware in places where Zerto is too expensive

• No support for object versions retention: There can be a retention policy(days or number) for object versions that are stored in S3 so that we don't have to worry about paying extra for all the old versions of an object in the bucket.
• No feature for replication within a region: Currently AWS does not support replication within a region. Also, having to enable versioning for buckets in which you need replication makes it even more costly.
• Confusing pricing: The pricing model of S3 can be a little confusing for a new customer with questions regarding data transfer from other AWS services, between buckets or data transfer to the outside world.

• For database restores, it has to restore the entire database in order to recover just one table.
• Backups of virtual machines with direct attached storage is difficult.
• I wish it covered cloud assets more thoroughly, like AWS ELBs and Security Groups.

• It practically eliminated some real heavy storage servers from our premises and reduced maintenance cost.
• The excellent durability and reliability make sure the return of money you invested in.
• If the objects which are not active or stale, one needs to remove them. Those objects keep adding cost to each billing cycle. If you are handling a really big infrastructure, sometimes this creates quite a huge bill for preserving un-necessary objects/documents.

• I am not privy to ROI, but just having confidence and trust that Commvault will back up whatever needs backing up, and that we will always be able to restore it quickly, allows our technical people to concentrate on the problem at hand, knowing that we do not have to worry about the safety of the data. This saves time for some very expensive human resources and shortens schedules by eliminating a whole class of data safety and disaster recovery issues.
