Is there a solution for mariadb-backup? I haven't been able to sync nodes or create a backup for the last 18 months on the 10.11 version.

Creating backups or syncing nodes via SST using mariadb-backup is a daily lottery, and rsync is often three times slower. Is there a solution to this issue, which has persisted for over 18 months?

Constantly the same error using it as a backup tool or to sync nodes:
Was only able to copy log from 192588736548402 to 192590016726207, not 192590016729428; try increasing innodb_log_file_size

Thanks
