Don't EVER copy  to database files while the server is running.
This is a guaranteed way to crash your database files.

Shutdown the server.
Copy the files.
Start the server.

Hi,

Using a sample database, I have tablea and tableb. I populate tablea
with some records and I can see the tablea.MYD file size increase on
the drive, while tableb.MYD remains at zero bytes.

Then I make a backup:
mysqlhotcopy -u username -p password sample ./backup

Next I modify the database:
I delete the records from tablea and insert records in tableb and
observe tableb file size increase on the drive, then I remove the
sample directory inside /var/lib/mysql which contains the sample
database

Now I restore it like this:
mv backup/sample .

and I see the tableb.MYD file get adjusted back to zero, as it was
before the modification, yet when I look at the database through mysql
and through mysqlcc, it still shows the modified database!

Anyone know why it isn't restoring to the original backup ?!?

Thanx,
