Backup With Mysqldump Takes Hours, Database Is Not That Big
Hello, I've been having some problems making database backups. I've searched all around and I notice that to most people it only takes a few minutes to backup huge databases (1+ gb).
My database is around 350mb and it can take up to 4-5 hours to backup, which I guess it not normal at all.
My server has a dual Xenon with 4gb ram, using mysql 5.0.27-1.fc6 and php 5.1.6-3.6.fc6. I am using Fedora Core6 with Plesk.
The database is around 350mb, with around 1.1 million rows. To backup I use
mysqldump -uroot -p database > backup.sql
As I said, the above takes hours. I guess it should take minutes?

Create Index Takes More Than 5 Hours
I'm running MYSQL on a windows xp laptop with an intel centrino 1.60 GHz Processor and 512MB RAM. I've created a table and imported 27 million rows of data. I wanted to create an index on one char(55) field, as this field is a key against which many selects will be made. The information in the field is not conducive to having an integer key as any queries would require an extra join to the look-up (reference) table. Creating the index ran for more than 5 hours and finally gave up when there was no more space on the drive (creating the index apparently consumed more space (11GB) than the actual table (8GB). I'm wondering if this is normal time and space consumption for 27 million rows. Finally, doing an un-indexed query on this table : SELECT * from historical where reference = 'abcd'; Takes more than 1/2 hour. Is this also a normal amount of time? I understand that people are using MYSQL for data warehousing and major transactional applications.

Where Is Mysqldump For Backup?
I bought a ReadyNAS Duo preinstalled with linux and have set up a local web server with PHP & mySQL (v 5.0.24a) and everything works great so far. Now I am trying to set up a daily automated mysql backup. I set up a crontab job which goes thru the motions and works but the backup file is empty. Next I tried to access mysqldump or even mysqlhotcopy I get "command not found" in ssh. I have searched all over the directory but these mysql utilities are nowhere to be found. I see "mysql" and "mysqladmin" but no dump utility. I am new to linux and understand basic commands. Can someone tell me how to accomplish a simple automated mysql backup? I also do not know how to retrieve the mysqldump module from the mysql package and install it (if that is the problem).

Mysqldump Backup To More Than One File
We currently use mysqldump to dump all our db's in quick mode to one file, backup.sql. This file has come quite large. mysqldump -Aq -u root > /MySQL/backup/backup.sql I would now like to split the mysqldump so that the output comprises of several files of less than 2 gigabytes each. Does anyone know the mysqldump options that could be used to do this? Or with using the > out command?

Mysqldump Without Locking Database
On my database I run a cron job every 12 hours to dump the database and store it on the hard drive using the below .sh file. The problem that I am having is that when it runs, it locks the database so my website quits responding. Is there another way to backup the database without locking it? We have a pretty large database which is locked for about 5 minutes which means we can not process orders during that 5 minutes. /usr/bin/mysqldump -u {databaseusername} --password='{databasepassword}' {databasename} > ~database-backups/db-backup_`date '+%F-%H%M%S'`.sql && cd ~database-backups/ && nice bzip2 *.sql

Backups Taken By Mysqldump Locks Database
i've made a backup / restore script which first dumps the content of the database with mysqldump and the copies the backup file to another location. What i find strange is that after mysqldump is finished with dumping the data and the copy operation is started, the database does not accept inserts or update. In our Java application (using hibernate) we are informed that tables are locked (even thoug they should not be). when the copy process is finished it works again!

Partial Database Backup
I am developing a hosting solution for a popular open source script: on the website users can sign up to get their own "virtual" copy of the script. There is a single database, but own tables for each user. Database tables engine is currently MyISAM, but I am going to change it to InnoDB. What I need is to let each user download a backup of own data, and restore it when s/he wants. The users shouldn't be able to change other users' tables structure/contents. Also, the backup should be encrypted, so they can't simply check out its contents. One of the possible solutions is to tar the tables files, encrypt the archive, and that would be the backup. But in case user decrypts the archive, s/he would be able to change table structure and other details, making the system function improperly. Of course, as encryption algorithm strength grows, it becomes harder to encrypt the archive and make the system work incorrectly and/or change other users' info. Should I just use some strong encryption algorithm and tar the table files? Does InnoDB allow to work with table files of an open database? Or should I lock the required tables for that?

How Do I Set Up A Regular Backup Of My Database?
I know I can do it manually in phpMyAdmin, but is there a way to set up a scheduled back-up say once a day? It would be even better if I could set up some sort of cycle where at any one time I'd have 7 versions backed up (Monday-Sunday) and each day that backup would overwrite its old version (that is, on Monday the db backup would be saved over the old Monday backup, and on Tuesday it would be saved over the Tuesday backup). Just in case something goes unnoticed for a couple days I would have the ability to jump back to a given day within a week.
