In Apache Doris 2.0.15, we introduced a new parameter: max_backup_tablets_per_job, which is used to limit the maximum number of tablets involved in a backup, to avoid OOM issues caused by excessive tablets. See https://doris.apache.org/docs/2.0/admin-manual/config/fe-config?_highlight=fe#max_backup_tablets_per_job.

This might prevent some existing backup tasks from running. If you have such issues, please adjust the parameter's upper limit accordingly.
