Brent Ozar mentioned there is nothing wrong about conducting transaction log backups during full backups. https://www.brentozar.com/archive/2015/12/what-happens-to-transaction-log-backups-during-full-backups/
Just inquiring if the same statement applies for maintenance plans below, running transaction log backups during:
(a) Index rebuilds and
(b) DB integrity checks.
I tested this on our system, functionally and cpu%/memory usage, everything seems fine.
I read from article above. I want to ensure same principle applies. "Take log backups during full backups. You can take them and nothing will break...Log backups during full backups won’t hurt anything, and may end up helping things if your full backup fails, and you need to restore something."
