When copying the files back.

cp –preserve=mode,ownership [path/to/backup/files] /var/lib/mysql/[db_name]

Using preserve will stop you having to use chmod and chown.

I got it working. Its because, when restoring the files, the owner of those files should be mysql. Thanks.

Hi,
Nice article.
I tried taking the backup and restoring using this mysqlhotcopy.
I issued the following cmd.
mysql> /usr/bin/mysqlhotcopy -u root -p pass appdb /tmp -allowold -keepold
Locked 16 tables in 0 seconds.
Flushed tables (`all the tables`) in 0 seconds.
Copying 48 files…
Copying indices for 0 files…
Unlocked tables.
mysqlhotcopy copied 16 tables (48 files) in 0 seconds (0 seconds overall).

NOTE: Here it dnt show 16*3+1. i dnt know why?

then i stopped and copied these backup under new database..

when i connected to new database it is showing error
Didn’t find any fields in table ‘Ar’
Didn’t find any fields in table ‘Arch’
Didn’t find any fields in table ‘Arist’
Didn’t find any fields in table ‘BITE’
If i described any table in that it is saying error
Can’t find file: ‘./newdb/Ar.frm’ (errno: 13)

Do u have any idea how to resolve this?
