A second CommServe is not necessary.
Commvaults goal, is to ensure backup data is "ready" when you need to do restores. Part of this strategy to ensure your CommServe is easily recoverable, and backup data is remained intact and valid so it can be recovered.
Here are a few ways that we can accomplish this:
- We have an on-prem method of isolating/air gapping backup data using network topologies and orchestration. Cloud is also a valid option if preferred.
- Our ransomware protection capabilites are inserted beneath the OS layer. Your mountpaths are still protected from ransomware and malicious attempts to delete even if the Commvault software is uninstalled.
- CommServe Live Sync will replicate your CommServe database to a standby CommServe (could be cloud based). This reduces recovery time of your CommServe and your ability to begin restoring data in the event the primary CommServe is corrupted.
- We support Direct to Cloud native copies of DR backups, so that your CommServe database is in native format in an S3 bucket (or any other cloud), where you can easily recover your CommServe in the event of a Ransomware attack.
- Lastly you can copy data to Cloud as a dash copy or use live sync.
I only briefly answered your question. I will contact you via private message if you are interest to have a more indepth strategic call. I would like to hear more specifically what your requirements are.
