veeam exchange backup

[cgeorge]

What is the best way and the amount of retention policies to backup an exchange server so you never lose mails.
Incrementals + synthetic full.
what is the best schedule scheme?

Carol, there is no such thing as best or universal retention and scheduling settings for any type of backup. All depends on RPO and RTO values accepted/required in your company, amount of changes produced by the given Exchange server, available resources, hardware, etc. You can search this forum for existing discussions on what our customers do.

I also recommend reviewing the following topic for some Exchange Backup Questions / Best Practices. Should give you some thoughts.

Thanks.
