Hi All,

Can anybody help me with different approaches identifying modified disk blocks in a filesystem? Is there any way to get list of modified blocks on filesystem and backup them?

I would like to detect the modified blocks and backup them since last backup (full or incremental)

Monitoring all write operations on files will take lots of time in case if there are millions of files. In that case block level reading will be faster.. can anybody pls help me on this?

Regards,
Kuldeep
