MYSQL :: Restore InnoDB Data

InnoDB Backup And Restore
I've just converted the tables in a big database (approx 27 million
records) from MyISAM to InnoDB. When I was using MyISAM I backed up
the database by stopping MySQL and then copying the MYI, MYD, frm
files in the database directory, and restored the database in the same
way.

Is there a similar way to backup and restore InnoDB tables, or do I
have to use the InnoDB Hot Backup tool?

InnoDB Constraints And Database Restore
We use InnoDB tables and foreign key constraints extensively. The mysqldump
backs up the database tables in alphabetical order with foreign key
constraints defined in the create statement of each table. These foreign key
constraints are violated at the time of restore. We have tried the following
two solutions...

(1) We have tried to backup the database tables in the order of their
dependencies. This works but the backup scripts need to be maintained
carefully as new tables are added/removed from the database.

(2) phpMyAdmin export does the database dump and puts the table constraints
as ALTER statements at the end of the dump. Unfortunately, the phpMyAdmin
dumps cannot be automated and I have not been able to push constraints to
the end of the backup using mysqldump.

Database Restore / MySQL 4.1 -- InnoDB
I have got a MySQL 4.1 that we use wit vBulletin.... We had a crash
last week and I've been able to restore the data up to September 2005
as it stands.

Now, I'm under the impression I could rebuild the data from the logs
but I cannot seem to figure out how to do that based on the tools and
instructions posted.

I've got my ib_log files (ib_log0 and ib_log1) also my ibdata file,
which is full of all the data i'm trying to get restored. Opening it up
in hex editor, I can see posts and information right up to the moment
the database crashed.

What steps should I take to restore the data from the log/data files?

I've tried several different steps, but I'm goofing it up somewhere I
guess. Are there some other tools available to help with this?

This site was a 'non-revenue' site, so I didn't exactly make all of the
redundancy arrangements that I would normally do for an Oracle/MSSQL or
any other live business database. I'm ateast going to enable mirroring
this time around and move the backups to another location.

Mysqldump And Restore Of Innodb Tables
We are on MySQL 4.0.21 on linux. We use InnoDB tables and foreign key
constraints extensively. The mysqldump backs up the database tables in
alphabetical order with foreign key constraints defined in the create
statement of each table. These foreign key constraints are violated at the
time of restore. We have tried the following two solutions...

(1) We have tried to backup the database tables in the order of their
dependencies. This works but the backup scripts need to be constantly
maintained as new tables are added/removed from the database.

(2) phpMyAdmin export does the database dump and puts the table constraints
as ALTER statements at the end of the dump. Unfortunately, the phpMyAdmin
dumps cannot be automated to the best of my knowledge.

Does anyone have a solution/script to backup databases with InnoDB tables
such that constraints will not be violated at the time of restore.

Restore Data By Copy The Data File
i have restored the data by copying the data file into c:mysqldataabc It works.

But, I have the problem as I want to copy another updated data files (*.frm, *.MYD, *.MYI) into the folder.

All data is lost! but, the size of the data file is not zero.

If I do the same action to replace the old data files, it works again.

Now, how would I can restore the updated data?

Restore Data
what is the difference between ?
1) mysql < backup_sunday_1_PM.sql
2) mysqlimport [options] db_name textfile1 [textfile2 ...]

3) Load data infile file

Restore To New Data Base
I am using a heavily modded PHPBB forum and want to convert all my posts, users, etc, into a new PHPBB forum using some other mods. I am using MySQL 3.23.58 .

I ran the conversion steps as the creator fo the modded forum stated but at the point where I run the install.php page I get an error that says "installation aborted as table xxxxxx already exists."

Is there a way around this like perhaps makign the new tables over write the old tables? I need to keep the tables as they are or I will lose the posts and such.

Possible To Restore Databases From Just The /data ???
possible to restore databases from just the /data folder??

Split Innodb Data File Into Smaller Data Files
we configured innodb configuration with default my.ini settings. now data file is increased more than 40 GB.After that we come to know that we need keep the settings like below

#innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend

so that it will keep on creating 2GB data files.
Now how we can change the settings and splitting the data file of 40 gb please.

I Need To Restore Data From My Backup Tables
I have installed Joomla and it created new database tables and took the existing ones and made them a backup. So I have one set that has a prefix of bak_ and the other set begins with jos_

How do I go about taking the data in the bak_ tables and inserting or copying it into the jos_ tables?

Restore Old Mysql Data To A New Schema
I have new version of paryoll application and hence now I have to restore my old backed up mysql data (old mysql data like *.frm,*.myd,*.myi has been zipped).Unfortunately this is not easy.

The new version has new schema (e.g emp_desc has been added in the new EMPLOYEE table).
Wondering if their is a good way for me to do restoration. Is their any mysql tool that does this automatically or I have to programatically find out of a schema change.

MySQL Cannot Backup And Restore UCS2 Data
Did a mysqldump and the UCS2 fields where dumped with insert statements with standard 8 bit ascii character strings, not UCS2.

Innodb Data File
i have just installed MySQL and am getting this message and i just need to know do i need innodb initially

Recover InnoDB Data
I'm running a fudforum and originally had MySQL setup to create InnoDB tables by default. I somehow got the idea that I should have the tables default to MyISAM so I changed my.ini to do that. I then ran an update on my fudforum. The update apparently recreated most of the tables. So now the tables are MyISAM where before they were InnoDB. Now they are also devoid of data! It appears as though the IBdata1 file still exists in the MySQL InnoDB Datafiles directory. I don't know if that's relevant or not.

Is there ANYTHING I can do to get that data back into my tables? I tried changing a couple back to InnoDB but that didn't seem to help.

Cannot Browse Data In InnoDB Tables
At present, I am using MySQL version 5.0.20 which I update via my spring application. Inside my configuration file I recently changed from: <property name="dialect">org.hibernate.dialect.MySQLMyISAMDialect</property> to <property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>. I did this because I wanted my transactions to rollback if they were not commited properly. However the problem I am now having is that I cant view the data inside my InnoDB tables (via my phpMyAdmin page). Whenever I click on the 'browse' button I get the following message: "MySQL returned an empty result set". However, I know data is inside the tables because the 'browse' button is not dissabled. If there is no data in the tables the button become dissabled.

InnoDB Data File Is Growing
My ibdata1 file is growing. Do I need to worry about that ? I am guessing it
will automatically delete old data to fit the size, correct ? Also how do I
limit the growth size. I tried to put max:2000M , but since my Innodb is
crashing and can't restart mysql I removed the whole my.cnf file all together to
fix the crash. So now I am not sure how I can prevent the growth of InnoDB.

Duplicate Existing Database (innodb), Structure Only, Without Data
There's a database (innodb) named "test1". I want to create a new database with exact the same strcuture, but since there are many tables in this db i do not want to retype the whole commands.

I'm looking for a possibility to duplicate this database, any ideas / tools?

MySQL Enterprise Server With InnoDB For Mission-critical Data?
However recently the company I work for has the requirement to upgrade their database system. The data here really is mission-critical and we can't afford to loose any of it, and we need 24-7 uptime, with good performance (we have lots of clients so there'll be heavy load), any downtime will cost us.

What I'd like to hear is peoples own experiences with MySQL Enterprise, good or bad, and if it's up to the job.

Looking around the net I've seen lots of supposed expert DBAs saying that there's no argument; you should go with one of the "big 3", these being DB2, Oracle or MSSQL. However I get the feeling Oracle and DB2 would be a massive task to configure, and MSSQL - well it runs on Windows, we can't have any downtime no matter how good people say it is these days.

So my idea was; InnoDB on 3 servers - a master and 2 replication slaves, with one slave off-site down a 10Mb line (wide enough pipe?). We use the on-site slave to run our daily backups, and point our reporting web sites at it too. the off site is for worst-case scenario disaster recovery.

How much would we be better off spending more Â£ on one of the "big 3"? Would our data be safer on these? Would we get better performance with these? Is there a better model I could use for the MySQL setup?

Restore Db From 4.1.12 To 3.23
I've a backup from my database running on mysql 4.1.12

Now i want to restore this to an old machine running 3.23.

How to do this. I get several errors.

DB Restore
I appear to be getting the following error message everytime I want to restore this database. The message is as follows:

Unable to restore database web1_wordp : ERROR 1064 (42000) at line 754: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '22:17:15)' at line 1

I'm not quite sure what this means :confused: - How would I correct it?

Restore
A customer passed me her backup, for me to open in my MySql. They are 50Mb of backup. MySQLAdministrator is being long a lot, very even to make the restoration in my machine (1kbps!!!!)

Restore
I've got a table with over 400,000 records. I did a mysqldump to ensure I could restore it in case of problems. Sure enough, problems arose and I needed to do a restore. The mysqldump created the usual create database, create table and one gigantic insert statement, where all 400,000+ records are inserted. I started my restore around 10pm or so yesterday and was surprised to wake up this morning and find it still running. Considering the dump itself took a couple of seconds, why is the restore taking so long? I'm building a website that's going to have tons of traffic. A database restore that's going to take multiple hours seems to be unacceptable. One way to speed up the process would have been to simply copy the actual database files and just stick them back in the data directory.

How To Restore Database
I think i will have to da a full resortation of a database.

lets assume old database is deleted.

So I go to my hosting control panel and create a new mysql database
Use same username and password as used in original

open phpmyadmin and do to the new database and select import-then import the file that I have as a backup--i have a file that I exported as a text file-a full databse export. it is about 4 mb so I hope can do it at one time

Is that basically how I can do it??

Mysql Restore
I have been running a mysql backend to phpBB on my home Gentoo based linux server. I recently switched the mysql and phpBB to run on a dedicated web server on my home network. I was using mysql version 4.1.14 and then 4.1.14-r1 on my new web server. The problem is that the character set seems to have gotten corrupted during the backup and restore process. The forum is based in French and hence a lot of the special characters have gotten messed up. I have even tried copying the my.cfg file from the old server to the new one but with no effect.

Stalled Restore
I Exported my MySQL database (60KB) (MySQL 4.0.24-standard) from iPowerweb hosting site.

I know want to restore it to my MySQL (mysql-4.1.13a-win32.zip) on my home server.

I loged on with MySQL Administrator, went to Restore, Opened .sql file, hit Start Restore, and it gets stuck at 9598 number of bytes each time I attempt it. Total is 60812 Bytes.

How To Restore A Database (.bak)
Recently I downloaded a ASP script, so I can use on my website, however in the instructions, it tells me the following : -

Restore the bbdf.bak SQL database with SQL 2005 (any edition) Management Tools

Now I have the file bbdf.bak, but I am not sure what I am suppose to do.

I have downloaded and installed Microsofts SQL 2005, but am totally lost as to what I am suppose to open and type .... ? ?

I would of thought it would be easier for them to just give me a .mdb file or something which I could use...

Restore Of Database
How do I go about restoring multiple databases at the same time. I know if I needed to restore 1 database I can do something like.

mysql db_name < backup-file.sql

but what if backup-file.sql consists of multiple databases (ie it was created using mysqldump-all-databases) , which database would I specify in the db_name section?

How To Restore .tgz Files?
how do I restore .tgz backup files using the mysql panel? I tried restoring it as a gunzipped file but it gave me errors.

SQL Database Restore
I upgraded to Tiger and it damaged my SQL database.

I have a backup file that is about 80 mb. The backup file was created
with PHPmyAdmin and is in .SQL format.

When I try to use PHPmyAdmin to load this .SQL file and restore my database, I get an error message that says NO SQL QUERY.

The file stops executing and NO data is restored.

Is this because the file is too big ??

Is there an application that will break the .SQL file down into smaller
parts ??

Is there a way to restore the data using the .SQL file and a direct SQL command line entry ??

Backup / Restore
I have this one FreeBSD box (nice Dell with one 40GB HDD). I have made a replica of the drive and put it on the secondary IDE channel. I want to do a restore of all the MySQL db's to the second drive right after the backup takes place from the primary drive.

The reasoning behind this is that this is the only system running this particular app and the company that wrote it went belly so, I NEED to have the ability to just swap drives bring it back up and be done.

Backup/Restore
I'm migrating a web site from my testing system on my local machine to the web host upon which it will live. My testing server is running MySQL v. 5.0.22, and the remote host is running 4.0.24. I am using MySQL Administrator v. 1.0.10 to run a backup and export my tables to an SQL file, and PHPMyAdmin to import the SQL file and run it on the server. At first, I was getting a 1065 - Query is Empty error. After reading through some of the postings here, I realized that some of the commented strings at the top of the file were unnecessary, and probably the cause of my error, so I removed them. I re-ran a backup that would only backup the appropriate tables and write the appropriate data (the database schema on my server is named differently, so I don't need to back up the full path). After editing the file to remove the uneeded stuff, I recieve a different error message, regarding an error in the SQL syntax of the dump file. The error in question occurs on a line that reads as follows:

)ENGINE = MYIASM DEFAULT CHARSET = latin1;

The error in question is as follows:

#1064 - You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'DEFAULT CHARSET=latin1' at line 21

I'm having a hard time finding the issue, and would really appreciate if somebody might point me in the right direction to help me create a backup file that my server will interpret charitably and restore the data I need. I'm getting to the point where I may have to re-enter it all by hand, and that thought depresses me quite thoroughly.

Slow Restore
Mysql 4.1.15 on Win2k. Using InnoDB.

Using the mysql administrator gui to create a backup, everything goes
fine, and restores quickly.

Using the command line:

mysqldump %dbname% --single-transaction > %dbname%.sql

creates a file about 15% smaller than the gui produces, and is
EXTREMELY slow to restore. I have tried adding locks, skip opt,
everything. What does the gui use for a command to create this dump?

Backup/restore
Working on a single machine (win2k) needing to do backups. Trying Backup
Table with the following syntax:

BACKUP TABLE tbldealers TO 'c:mysqlackups'
BACKUP TABLE tbldealers TO /mysql/backups

I've tried with/without quotes, ticks, nothing except the path. I either
get error in syntax, or I do get 1 row in set, but there are no files in
that directory.

Any help would be appreciated.

I've read the manual as extensively as I know to and can't find anything on
backup table syntax.

I'd prefer to stay away from mysqldump and mysqlhotcopy and control the
backups myself.

Backup And Restore

Restore Table
I am using mysql on my local machine, Windows operating system. I accidently execute an update statement without where condition, so I messed up all the records in this table, is there any solutions (or tricks) to restore data? I did not have any backup yet.

Restore Databases
Trying to restore some mysql databases that were on a hard drive which has crashed.
Although the DB's were supposed to be backed up ... it appears they were not backed up properly as I can access the drive but can only find the FRM files.
There are no MYI or MYD files on the old drive.
Is it still possible to restore my databases and tables with just the FRM files ??

Restore Query
I am restoring the backup I took from other server
so I ran
mysql tempo < file.sql

It runs fine for sometime and I can see the tables in the database tempo in mysql but it never stops and keeps on running
Is there anyways I can change the command to get output on console on the progress or anywhere I can read the logs which statement it is stuck in?

Backup / Restore
I have recently installed a Fedora server - something new to me. I am just trying to get my mysql database from my old windows server, onto my fedora box.I have tried, mysql_administrator to create backups and restore but it hasn't worked.I have also used the following two commands from root to do it:

mysqldump -u charlie -p -h 10.10.10.3 --all-databases > /test.sql
(to read from the windows server and create a dump on the local machine)

followed by:

mysql -u root -p < '/test.sql'
(to try and resore the backup to the fedora box)

I got the error:

ERROR 1054 (42S22) at line 6854: Unknown column 'cl.COMPONENT_ID' in 'field list'

Restore A Backup
I have made a backup of my phpbb forum db. For some reason I can't get it restored. I'm running my own server on linux, the only thing is I'm new to this too. lol I was wondering if there's a way to transfer ther MySQL file and just have it merge itself into the MySQL system? I have access to the console if that helps. Sorry if I sound confusing.

How do I restore a database after mysqldump? I read an article published in devshed and I followed their steps but...

Restore Backup Sql
If I backup the database using
shell> mysqldump --all-databases > all_databases.sql

How do I restore it? Mysql documentation only mentioned below:
shell> mysql db_name < backup-file.sql

This is only to restore one databas, not ALL databases I wanted. My guess would be
shell> mysql < all_databases.sql

Is that correct?
