EMC Backup & Recovery Manager?

Can anyone point me to the current Dell EMC documentation for EMC Backup & Recovery Manager (not to be confused with Dell Backup & Recovery Manager)? I thought it was EOL some time ago but the Avamar 19.1 admin guide still refers to it so now I'm not so sure. But I cannot find current documentation for it anywhere on the main site.

If it is EOL do you know what has replaced it? We have BRM from a long time ago but we're not using it - I'd like to get rid of it if I can, but want to be sure doing so isn't going to impact our environment at all.

Thanks.
