Commvault Complete Backup & Recovery vs Dell EMC Avamar

• 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

• Avamar performs data deduplication on the remote host. This greatly reduces the amount of traffic that each backup requires. This even applies to the virtual environment through change block tracking. Backup times are reduced from hours to minutes.
• The management interface makes it easy to configure and maintain data retention periods. Many times certain data must be kept for an extended period of time. There is a specific menu for managing retention periods.
• The system is able to recover itself from a hard failure with virtually no loss of backups. There is a checkpoint taken each day that provides a recovery point in the event of a catastrophic failure. Since this is a node based system, the loss of more than one node could require a recovery be performed.
• While another grid must be purchased, the replication utility allows all backups to be replicated to another grid at a remote location. This ensures the resilience of the backups in the event there is the loss of the primary data center.
• Also works on HCI devices performing image-level backups as in our primary data center environment
• There is also now an All-in-One appliance for smaller locations

• Commvault Complete Backup & Recovery has developed the concept of plans that work great in smaller institutions but can hamstring large enterprises by the limited flexibility. There are situations where plans appear to be forced into decisions. Ideally, providing the ability to disable plans would be beneficial.
• The security model is granular in respects to permissions and ability to implement it for a single object (client, user, job). Implementing the correct collection of permissions can sometimes feel like opening a padlock. This appears to be a great place to implement a wizard for guiding administrators through desired behaviors and building the appropriate security role.

• The client interface has constant JAVA issues and can be slow and chunky. We have often had issues with current versions of JAVA breaking it so it will not even run.
• The backup clients are split out for function. Although this makes them light, it also makes it cumbersome to upgrade clients. The naming scheme can also be confusing for the clients.

• The ease of use and reliability of Commvault have enabled us to support the entire environment with less personnel than other products. We can support hundreds of clients and 500TB of protected systems with a single person.
• Their per TB pricing can get rather expensive often forcing you into an agent based pricing model and that can be less that ideal to mange.

• Avamar served our organization very well for many years. It was absolutely the best solution of its day.
• We did the fork-lift upgrade twice to continue with Avamar. We could not continue to support this model of upgrades.
• Our final decision to replace Avamar was when the nodes filled with meta-data while we had plenty of data domain space for backups.
• We've spent too much engineer time babysitting the product.
