[Backups] Running out of Storage

I’ve been getting this email recently :

Hey Mike!

You’ve reached 75% of your Snapshot Pro storage limit. To continue backing up your websites without hitting your 150 GB limit, consider setting the Storage Limit for each site to a lower number.

You can adjust that for each site individually either in the wp-admin (under Snapshot Backups > Settings) or in your Hub (under Backups > Settings).

Via The Hub I’ve changed each site’s backup schedule from mostly Daily to either Weekly or None

1) Will this solve the problem?
2) Where can I find out how much total backup storage I have? I know I have been in that section before but cannot find it.

Thank you.
