Question about SQL backup

Hi,

I have a question about MS SQL backup. I have created below job.

• Daily full backup job for database
• Incremental backup job for transaction log (repeat every 2 hrs)

Problem is incremental job (for transaction log) failure at 2pm, then I run it again.

Finally, job succeed but I found in "SQL/Full" in backup set, but not "SQL/Log"

Please advice.

Thanks !
