Veritas Alta Recovery Vault has positively impacted my organization because in case some users left, I don't care if they delete their old archive files because I have backup for their emails or OneDrive, even SharePoint.
The issue I face with Veritas Alta Recovery Vault is that if I need to move from their service to other solutions, there is no clear idea about the grace period to migrate the backup data to another solution, and it relies only on the user.
