Which cloud providers can I set up my storage bucket with?
You can use either Google Cloud Storage or Amazon S3.
Can I have more than 1 storage bucket for Backup?
No. You can only have 1 bucket rather than different buckets per OU for example - this would cause complications if a user were to move OU/Smart team or change backup policy or any other action.
Can I use the same storage bucket for CloudM Backup and CloudM Archive?
No, the storage bucket you use for CloudM Backup cannot be the same bucket as the one you use for CloudM Archive.
