I simply grep out the noise, a backup can be rerun if you need to debug

That is not true if the error is not reproducible (although one might wonder if debugging is needed then) or in case of a heisenbug.

but for nightly and snapshots, if it doesn't fail...the only portions of the logs i see, and need to see, are what i've determined after 100xN times of running mariadbbackup. YMMV, but its really easy not to filter out errors.
