Email Archiving

Time to review all the systems we are running and look if they are still needed and what other options out there.
We have a Barracuda Email Archive that has been running for 7 years, looking at cloud service, replacing it, or do we need it at all anymore?
How many of you at your Church, Organization or Business run a full email archive on your email system? If yes, what are you using?

We keep 30 days of backups via Veeam, and some accounts have fulltime archiving on them due to legal risk.
