Subject: question about ext4 backup block group descriptors

hi,

Anyone can help answer when ext4's backup block group descriptors are updated?
I had used blktrace to track the corresponding backup block group descriptor
block, but didn't find that any backup blocks were written.
Thanks in advance.

Regards,
Xiaoguang Wang
