Hi,
i've been already reading the documentation the whole day, but still confused
and unsure what to do.
We have two databases which are important for our work. So both are stored
hourly. Now I recognized that each database has a mixture of MyISAM- and
InnoDB-tables. A backup of this mix does
for saving
MyISAM-tables. For InnoDB-tables --single-transaction is useful. But both are
mutually exclusive
(http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html#option_mysqldump_single-transaction
). The dump of both take about 10 seconds. If the db is locked for that
period I can live
XTrabackup can handle both InnoDB and MyISAM in
a consistent way while minimizing lock time on
MyISAM tables ...

Hi Reindl,
I'm sorry if I ask wrong question here?
I'm new to this and people before me did the terrible mistake of using

Hi,
if you want to copy from one server to another can't you just use
mysqldump? This is then restored via the mysql command using a pipe
or STDIN redirection. If you can shutdown the database for the
duration of the copy then you can do cold backup of all data files.
Both options will

Hello again!
I am trying to convert my tables to InnoDB, and i am getting an error...
Error: 1075
Incorrect table definition; there can be only one auto column and it must be
defined as a key
Now, I converted a table in my sandbox earlier this morning to do some
testing, and it worked fine...
If you have a column defined as auto_increment, there must be a key on it.
This is true both in myisam and innodb.
If you need further help, please show us the full structure of the real table
you're operating on (not the one from your sandbox), the statement you run, and

file (my.cnf) to ensure future tables get created with the desired
storage engine (unless otherwise specified in your create statement).
