Hi Shridhar, SQL Server backups don't cause blocking like what you have described above. Backups are resource intensive for disk as the pages are having to be read from disk and written back out to hopefully a different disk. Its possible that latency from the backup running is what is causing your issues. Have you done any troubleshooting to look at file statistics, wait statistics, waiting tasks, or other metrics?

What are the waiting task, if Backup is listed, what it is waiting on? Anything else. You would typically see things waiting, but what are the duration. Please provide as much detail about your environment. # of cores, memory, disk, where you are backing up to (URL, network share, backup device, local disk??) Has this always been happening or just recently started, more details are better.

And what else is happening on the server? Any other metrics you care to share? memory usage, cpu usage, file statistics, , , , , there is so much more information you can share, otherwise none of us here are going to be able to help you with you providing so little details.
