MYsql database restore difficulties

Hi

At night i have a script that is run by cron to backup a mysql database.

The script is:



#!/bin/bash
echo "Database Replication"
echo "Exporting Database"
mysqldump -u****** -p***** databasename > /backups/dumps/databasename.$(date +%Y).$(date +%m).$(date +%d).sql
echo "Database Exported"
echo "Compressing Database"
tar -cvzf /backups/databasename.$(date +%Y).$(date +%m).$(date +%d).tgz /backups/dumps/databasename.$(date +%Y).$(date +%m).$(date +%d).sql
echo "Copy file to Windows Server"
cp /backups/databasename.$(date +%Y).$(date +%m).$(date +%d).tgz /mnt/win/
echo "Databases Compressed and moved"
echo "Finished"



If i try and restore the backup to a test database on the same server i get the following error

ERROR 1064 (42000) at line 57040868: You have an error the manual that
corresponds to your MySQL server versio use near 'NULL,'0002132153','0002132153-3','2006-11-0     523,NULL,NUL' at line 1


If i do a manual dump and then restore it works without a hitch.

Help please.

HI!

Did the cron-backup/server report any errors at the time when the backup was taken ?

Hi!

And you are moving data from Linux to Windows  or different versions of MySQL ?

Hi!

Can you post the lines around the line that has this data (5 lines before and after) from the dump.
'NULL,'0002132153','0002132153-3','2006-11-0     523,NULL,NUL' at line 1

This seems to be some data issue that the parser doesn't know how to deal with.

im a bit confused but i looked at the .sql and there are only approx 4000 lines.

what does "at line 57040868" mean

Hi!

That is the line of the code of MySQL for bug purposes i think.
You should look at the values that either are in line 1 of your dump file or somewhere near.

I found the issue.

The script was running over the top of itself from another source and corrupting the backup files.
