Just one question, in terms of time scales what time period does the 640GB represent? For example; is it a week, a month, or more worth of logs?

If that logs represent weeks of logs then you'll need to ask yourself if there is any benefit for you to keep that historical data for that period of time.

Also, why don't you install an additional hard drive into the server, a couple of TBs and then point your logs to the new hard drive meaning that Exchange will automatically write the logs to the new HDD. You could then set a historical time stamp on the logs so that the oldest logs are automatically deleted from storage thus freeing up your storage, and also preventing you from having to move such large data sets to external media. Copying that lot over to the external is going to take a long time, you're not going to be able to fit it all on to the drive anyway, and are you going to need to refer to that amount of logs for anything in the near future?

Second internally installed HDD and point your logs to it and assign a hitorical time stamp.

above suggested line set a historical time to stamp on the logs.
how i can perform on my server that logs will automatically deleted from the D drive.
one more thing is it required or directly deleted from the location monthly log files.

suggest us on the is it required to store?

You don't backup the log files.
The log files are designed to fill in the gap between the last backup and a system failure.
Therefore if you do an Exchange aware backup of the databases those logs will be flushed.
The logs on their own are close to useless to you, ideally you need a backup to use them with.

What kind of backup are you currently taking that isnt purging your log files after backup ?

Ideally if you know you havea good Online backup being taken i would simply move all log files older than 1 day to another location and remove it after a couple of days as my Exchnage works fine.
