Restore from a MySQL dumpfile

timvw — Thu, 12 Jan 2006 00:16:52 +0000

If you are a longtime user of mysqldump you may have experienced that restoring with mysql < dumpfile doesn’t always work because of referential problems. Here is a little script that takes care of it: mysql-restore.txt.

Backup script

timvw — Sun, 27 Jun 2004 22:55:15 +0000

The current shell server i’m using returns bogus output for commands like df. Mind the negative value for 1-k blocks.

timvw@localhost:~$ df

Filesystem	1k-blocks	Used	Available	Use%	Mounted on
/dev/hda1	-780429856382	1	0	74%	/

It thought it would be a good idea to have a backup once in a while, but most of the times when i did it, i forgot to backup my database. So i wrote a little backup.script that remembers to do that for me.

#!/bin/bash

############################################################################### 

# Generate a backup file of homedirectory and database

# Update: 2005-09-16 01:56:00

###############################################################################

# dump database 

mysqldump -u username -ppassword -h invalid.org dbname > ~/mysql.dmp

# generate gzipped archive of homedirectory

tar -czf /tmp/backup.tgz ~

# move backup to homedirectory and change name

mv /tmp/backup.tgz ~/madoka-`date +%F`.tgz

# remove database dump

rm ~/mysql.dmp
