I am working on a proposal for a large Korean manufacturing company that is migrating its IT infrastructure to AWS.
1. Backup environment
- Backup Source: AWS EC2 VMs, Veritas Cluster File System, File Data
- Backup Storage: AWS S3 Object Storage
2. Unusual characteristics of previous backup tests
- Tested Backup Solutions: Veritas NetBackup, DellEMC NetWorker, Veeam
- When backing up the environment using AWS EC2 VM and Veritas Cluster File System to S3 storage, AWS EBS storage was used as the cache (staging ?) area.
- In particular, the Veeam solution used more EBS storage as a cache (staging ?) area than Veritas NetBackup and DellEMC NetWorker.
3. What needs to be confirmed
1) When performing a backup for the above environment with Commvault, is AWS EBS storage used as the cache (staging ?) area?
- The conclusion that the customer reached after discussion with AWS and Veritas is that all backup solutions will use AWS EBS storage as the cache (staging ?) area.
2) If AWS EBS storage is used as the cache (staging ?) area, how to estimate the expected usage?
- Can you technically explain that it will be using Veritas NetBackup or DellEMC NetWorker level, rather than using high-capacity EBS storage like Veeam?
When a customer selects a Backup solution, the size of the capacity using EBS storage will have a very large influence.
