Thanks jgt,
You are right. But the problem here is the number of files are so high and volume of the each files in GB's. It will take a huge amount of time to zip and unzipping process. Also It is not possible to send the entire files at a time. The file transfered on the basis of network traffice. Thats why I need this kind of checking.
Please help.
Thanks in advance.

innochecksum
INNOCHECKSUM(1) MySQL Database System INNOCHECKSUM(1)
NAME
innochecksum - offline InnoDB file checksum utility
SYNOPSIS
innochecksum [options] file_name
DESCRIPTION
innochecksum prints checksums for InnoDB files. This tool reads an InnoDB tablespace file, calculates the checksum for each page, compares
the calculated checksum to the stored checksum, and reports mismatches, which indicate damaged pages. It was originally developed to speed
up verifying the integrity of tablespace files after power outages but can also be used after file copies. Because checksum mismatches will
cause InnoDB to deliberately shut down a running server, it can be preferable to use this tool rather than waiting for a server in
production usage to encounter the damaged pages. innochecksum supports files up to 2GB in size.
innochecksum cannot be used on tablespace files that the server already has open. For such files, you should use CHECK TABLE to check
tables within the tablespace.
If checksum mismatches are found, you would normally restore the tablespace from backup or start the server and attempt to use mysqldump to
make a backup of the tables within the tablespace.
Invoke innochecksum like this:
shell> innochecksum [options] file_name
innochecksum supports the following options. For options that refer to page numbers, the numbers are zero-based.
o -c
Print a count of the number of pages in the file.
o -d
Debug mode; prints checksums for each page.
o -e num
End at this page number.
o -p num
Check only this page number.
o -s num
Start at this page number.
o -v
Verbose mode; print a progress indicator every five seconds.
