I've read over the thread and BackupPC is in this case not
correctly.
I know this isn't a fix but at least it's a step forward.
I removed libnss-ldap auth-client-config ldap-auth-config
ldap-auth-client libpam-ldap
I reran pam-auth-config and disabled the auto creation of home-dirs and
systemd registration that I had enabled for ldap support.

Hi
Surely disk io would affect normal rsync as well? Normal
incremental backups for this host as well.
thanks in advance!
Try using tar instead of rsync, you are correct that for large file
trees rsync is very slow and also RAM intensive when it's building the
filetrees
