# Examples

## Simple Usage

Just running mydumper without any options will try to connect to a server using the default socket path. It will then dump the tables from all databases using 4 worker threads.

## Regex

To use mydumper‘s regex feature simply use the --regex option. In the following example mydumper will ignore the `test` and `mysql` databases:

    mydumper --regex '^(?!(mysql|test))'

## Restoring a dump

Mydumper now include myloader which is a multi-threaded restoration tool. To use myloader with a mydumper dump you simply need to pass it the directory of the dump along with a user capable of restoring the schemas and data. As an example the following will restore a dump overwriting any existing tables:

    myloader --directory=export-20110614-094953 --overwrite-tables --user=root

## Daemon mode

Mydumper has a daemon mode which will snapshot the dump data every so often whilst continuously retreiving the binary log files. This gives a continuous consistent backup right up to the point where the database server fails. To use this you simply need to use the --daemon option.

In the following example mydumper will use daemon mode, creating a snapshot every half an hour and log to an output file:

    mydumper --daemon --snapshot-interval=30 --logfile=dump.log
