backup: mysqldump or mysqlhotcopy ?
hello, i'm new to MySQL, so i have currently some basic questions. I have a MySQL-Server with 15 users. Every User can create databases. I expect that the amount of data which has to be backuped will increase constantly. What i want: I'd like to have a backup on a regular basis. I think i will create two cronjobs, one running daily, the other running weekly. Initially, we will have just MyISAM tables, later on maybe InnoDB tables. I'd like to backup _all_ databases, but having the possibility to restore only some databases. And the number and names of the databases change often, but i don't like to adapt my script regulary. Which tool do you recommend ? mysqldump or mysqlhotcopy ? Can i backup all databases with mysqlhotcopy using mysqlhotcopy --regexp=[a-zA-Z0-9]\+ ? Can i restore from this backup only some databases just copying the saved directories of the backuped databases to the MySQL-directory ? Thanks in advance.

does mysqlhotcopy affect the key buffer?
i run mysqlhotcopy on each database once every three hours. i happened to be running my cache warmer this afternoon, which logs timing for a bunch of standard randomized queries, that when the backup script ran, the query times increased by a factor of about 20 from a nice quick pace back down to what i'd expect for an empty cache. hot times then slowly settled back down to the faster pace as i would expect as cold caches warm up. (i really don't know if key or table caches are the bottleneck.) so i was wondering if mysqlhotcopy has affecting the caches. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org
mysqlhotcopy
I am trying to use mysqlhotcopy on 2 different machines and I am having trouble on both of them. On the first machine, which is a Sun Solaris running mysql 4.0.15a, when I give the mysqlhotcopy command, I get the following error: DBD::mysql::db do failed: File './zemed/form_342.MYD' not found (Errcode: 24) at /usr/local/mysql/bin/mysqlhotcopy line 449. The file zemed/form_342.MYD does exist, but it's size is 0. On the second machine, which is a linux machine running mysql 5.0.45, when I give the mysqlhotcopy command, mysqlhotcopy web_positions /tmp/web_positions I get the error Invalid db.table name 'web_positions.web_positions`.`acadsec' at /usr/local/mysql/bin/mysqlhotcopy line 855. If I try to copy the mysql database, I get the error Invalid db.table name 'mysql.mysql`.`columns_priv' at /usr/local/mysql/bin/mysqlhotcopy line 855. Does anyone have any suggestions as to what I can do to get this to work. thanks. -- Malka Cymbalista Webmaster, Weizmann Institute of Science [EMAIL PROTECTED] 08-934-3036 -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
mysqlhotcopy errors osx
The first time I tried to run the mysqlhotcopy script, I got an error
that indicated that Perl couldn't find the DBI module.
So, I found a site (http://www.quicomm.com/apm_dbddbi.htm) that
stepped me through making and installing
MySQL DBD and the DBI modules(? don't know if I'm using the right
terminology here)
However, during the 'make' step of the DBD module I got a warning:
prompt$ sudo Perl Makefile.PL
Checking if your kit is complete...
Looks good
Warning: prerequisite Net::MySQL 0.08 not found.
Writing Makefile for DBD::mysqlPP
So I decided to try to 'make install' anyway and I got...
$ sudo make install

Installing /usr/local/man/man3/DBD::mysqlPP.3pm

mysqlPP/.packlist
Appending installation info to //System/Library/Perl/5.8.6/darwin-
thread-multi-2level/perllocal.pod
trying to run mysqlhotcopy again, I got...

Perhaps the DBD::mysql perl module hasn't been fully installed,

at /usr/local/mysql/bin/mysqlhotcopy line 178
line 178 of the script looks like:
my $dbh = DBI-connect(dbi:mysql:
$dsn;mysql_read_default_group=mysqlhotcopy,
$opt{user}, $opt{password},
should I change the dbi:mysql part to dbi:mysqlPP ???
or should I fix the earlier warning about Net:MySQL 0.08 not found
first. Do I just install the Net package?
...OK
I actually downloaded and installed Net:MySQL...
sudo Perl Makefile.PL
sudo make
sudo make test
sudo make install
...all went ok
then I did the same steps for DBD
...all went ok and no warnings...
But I'm still getting the same 'line 178' error.
What am I not doing correctly?
Thanks.

Re: mysqlhotcopy errors osx
DBD::mysqlPP is the pure Perl driver for DBI. Is there a reason you are
using that instead of DBD::mysql? I haven't done Perl/MySQL on OS X
before but on other platforms (and from the error you're getting here)
DBD::mysql is the typical driver for using DBI with MySQL. It also is
the driver that mysqlhotcopy is built to use.

Mysqlhotcopy and replication
I've got a replication slave db (all MyISAM tables) that I currently back up every night by stopping MySQL, tarballing the table files, then starting MySQL up again. I'd like to use Mysqlhotcopy to do this so that the db can stay up for reads while the backup is being done. Here's my question. While the tables are flushed with read lock, what becomes of all the Insert,Update and delete queries that come in via replication? Will they be applied after the backup is done and the tables unlocked?

Re: Mysqlhotcopy and replication
Jeff, that is indeed the case - the replication thread will freeze just like any other thread, and pick up where it left off. In fact, the statements are still replicated to the slave by the replication thread, stored in the slave's relay-bin file I think. Therefore even though the slave data is not being updated, the slave is in a sense staying current with the master even during the hotcopy (though you would have to wait for all those statements to be applied for the data to be synchronized).

MySQLHotCopy Error
We're having a problem with MySQLHotCopy. It has worked flawlessly in the
past but now we're getting an error message similar to this:
Dumping database... DBD::mysql::db do failed: Can't find file:
'./file.frm' (errno: 24) at /usr/local/mysql/bin/mysqlhotcopy line 468.
Deleting previous 'old' hotcopy directory ('mydirectory')
Existing hotcopy directory renamed to '/mydirectory/db_name_old'
done.
The frm file it can't find varies with each attempt to use MySQLHotCopy.
The files are there. We've flushed, optimized, and repaired all the tables
in the database without any luck. The db appears to be working fine.
MySQLHotCopy works ok with other databases on this server.
MySQL 4.0.23
Server: Mac OSX Server 10.3.8 dual 1.33 Ghz PPC G4 with 2 GB SDRAM
DB has 274 tables with 1.6 million records. DB size is 400 MB.
Any insights would be greatly appreciated.
TIA

Hello, Anyone here run mysqlhotcopy? I've read the docs on it but they are basicly just a howto and don't go too in depth. I've got a DB that is the back end to a 24/7 application. I ususally do backups from a replicated db by shutting down the Replicated DB then doing a tar are all the db files, then starting the db when done. Does mysqlhotcopy allow you to take a full snapshot of the db without needing to shut it down? What happens to read writes and updates while mysqlhotcopy is running?

mysqlhotcopy in replication setup run from slave
So, ran into a problem with using mysqlhotcopy to build a backup capable
of starting a new replicant. The current option (record_log_pos)
attempts to get master info from show master status, regardless of
whether running on master or slave. It also uses show slave status to
see where the slave is in processing master logs. I have found two
problems with this ...
- seems show master status returns nothing if you are not a master (and
not logging a binlog)
- takes the log position from the Read_Master_Log_Pos, which is only
what the IO thread has read, and not what has been applied
I have patched to add a new option --on_slave, which changes the
behavior a bit. It now does not run show master, but instead gets all
data from show slave status. It uses the Exec_master_log_pos to get the
current log position and dies if Slave_IO_Running is not Yes.
See attached patch. Any comments? Does this make sense to people? Any
better ideas? I can say that this works, whereas the default does not.
Meaning, I am able to take a snapshot, and build a new replicant off
of that using the data retrieved from (record_log_pos).

use mysqldump and mysqlhotcopy together?
Greetings, I've been looking at the backup/recover related discussions in the list archives for a while. Seems to me most people use either mysqldump or mysqlhotcopy. We don't have a good MySQL backup scheme in place yet. Now I have some questions based on my reading. How do I know how each table was created if using mysqlhotcopy solely if recovery needs to re-create the tables? On the other side, my concern about just using mysqldump is it may take long to backup and recover. The size of all the databases we want to back up is about 5G. We can only allow the databases unavailable for access for a couple of minutes at most if downtime can not be avoided completely. So I'm thinking about making use of both mysqldump and mysqlhotcopy together. By that I mean using mysqldump to dump table structures only (without any data) once a week so I can know how the tables were created in the first place and using mysqlhotcopy to backup actual database binary files every day. How bad is my idea?

I opted for using both mysqldump and mysqlhotcopy. Disk is cheap and everything is automated so why not. I have turned on the binary logs to facilitate a point in time recovery. As part of the mysqlhotcopy backup I flush the logs and copy the previous days logs to another location. I figure that I will use the hot backup and the binary logs for any disaster recovery and the dump for troubleshooting problems. Evelyn -Original Message- From: Bing Du [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 10, 2004 11:50 AM To: [EMAIL PROTECTED] Subject: use mysqldump and mysqlhotcopy together? Greetings, I've been looking at the backup/recover related discussions in the list archives for a while. Seems to me most people use either mysqldump or mysqlhotcopy. We don't have a good MySQL backup scheme in place yet. Now I have some questions based on my reading. How do I know how each table was created if using mysqlhotcopy solely if recovery needs to re-create the tables? On the other side, my concern about just using mysqldump is it may take long to backup and recover. The size of all the databases we want to back up is about 5G. We can only allow the databases unavailable for access for a couple of minutes at most if downtime can not be avoided completely. So I'm thinking about making use of both mysqldump and mysqlhotcopy together. By that I mean using mysqldump to dump table structures only (without any data) once a week so I can know how the tables were created in the first place and using mysqlhotcopy to backup actual database binary files every day. How bad is my idea?

We don't have a good MySQL backup scheme in place yet. Now I have some questions based on my reading. We use mysqldump and then a standard backup tool triggered by cron to backup the file it creates. If you use mysqldump without the -d or -t flags, you will get the sql necessary to recreate the tables as well as the insert statements necessary to populate the tables. For our particular application (which generates large amounts of DB reads and very few inserts/updates/deletes) we found that using mysqldump gave us an accurate snapshot of the data and was less to back up since the indexes in our case can get quite large. We've been using that method for quite some time with good results. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
mysqlhotcopy as a replication scheme
I've got an application that uses a fairly large (~50MM rows, ~1GB of disk) table of read-only data. The table changes maybe once a month, but when it changes, (almost) EVERY row in the table changes. The app needs to be replicated into several datacenters worldwide using relatively slow backend links. For this reason and others (I need to be able to control when each datacenter picks up updates, etc.) native MySQL replication isn't attractive. I'm considering building a scheme where I insert the data into a table once and ship around a gzipped mysqldump and load it into each datacenter -- this is easy, uses less bandwidth, is easy to control via cron and fits well into the rest of our infrastructure. Then I found mysqlhotcopy. Neato! I've tested, and this seems to work: 1) use mysqlhotcopy to copy the table on the replication master 2) gzip the table/index/data files and ship them someplace remote 3) (on the slave) unzip them 4) LOCK TABLES foo WRITE 5) FLUSH TABLE foo 6) copy the unzipped data files over the running mysql data files for the single table I'm intersted in. There's clearly a problem here if the machine crashes during this step, but it can be worked out to just 3 calls to rename(2), which is atomic on a POSIX fs, so that's less an issue than it could be. 7) FLUSH TABLE foo 8) profit! It looks like table foo now contains the new data. It takes a LOT less time than reinserting all the data into the table. Other than you should really use mysql native replication, does anyone have any comments on whether this is likely to be reliable, or why it's a bad idea? I'm using 3.23.49 (Debian stable); Is FLUSH TABLE likely to change in future versions in a way that will break this? -- thanks, Will -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
MySQLHotCopy - No tables to hot-copy HUH?!
I have a problem using mysqlhotcopy. Everything was fine until I recently
moved to a different server. Old one was running mysql 4.0.15 on FreeBSD
4.8, new is mysql 4.0.16 on FreeBSD 4.9.
The error returned is No tables to hot-copy at
/usr/local/bin/mysqlhotcopy line 379.
I ran w/ --debug and here is the result...
mysqlhotcopy drew /storedarea/drew -u alloweduser -p notpostedhere --debug
Filtering tables with '(?-xism:.*)'
$VAR1 = [
{
'index' = [],
'src' = 'drew',
'raid_dirs' = [],
'tables' = [],
'files' = [

'homework.MYI',
'homework.frm',
'teacher.MYD',
'teacher.MYI',

'users.frm'
],
't_regex' = '.*',
'target' = '/storedarea/drew'
}
];
No tables to hot-copy at /usr/local/bin/mysqlhotcopy line 379.
Here is a show tables from the terminal...
mysql show tables;

I would greatly appreciate some help here.
Thanks.

If you use --suffix option you should not specify location, because in this case
mysqlhotcopy create a new database, f.e. staff091703, in the MySQL data dir. That is
why you get incorrect database name error.

syntax form (shown in the mysqlhotcopy page of the MySQL manual):
mysqlhotcopy db_name_1 ... db_name_n /path/to/new_directory

* Perl 5.6.1
* Mysql 4.0.9-gamma (although we've tried mysqlhotcopy on three

Thanks for any insight. This is driving all of us crazy. Also looked all

I'm running mySql 3.23 on OS X 10.2 and I've reached a bit of an impassse with mysqlhotcopy, after having to re=install dbd and dbi, I keep getting the error: DBD::mysql::db do failed: You have an error in your SQL syntax near '` READ, `trypanofan`.``construct`` READ, `trypanofan`.``dapi`` READ, `trypanofan' at line 1 at /usr/bin/mysqlhotcopy line 438. there appears to be a workaround in the manual (http://www.mysql.com/doc/en/mysqlhotcopy.html) which indicates it's the method of quotation and suggests modifying 'quote_names' - unfortunately I have no idea where 'quote_names' is or where it's supposed to be. any suggestions would be lovely... thanks -s -- __ Seth Redmond DNA resource and Database Curator Wellcome Trust Laboratories for Molecular Parasitology Department of Biological Sciences Imperial College London SW7 2AZ [EMAIL PROTECTED] __ -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

mysqlhotcopy / bin-log manipulation
I have a question regarding mysqlhotcopy's use. I'd like to use the --flushlog option in order to have a nice backup synchronized log for my replication slave in case of recover need (without stopping the master). But the lock used by mysqlhotcopy made me split the backups into something like: mysqlhotcopy db_name_1 db_name_2 mysqlhotcopy db_name_3 db_name_4 db_name 5 mysqlhotcopy db_name_6 (that way because the backup of db_name_1 and db_name_2 is fast and I don't want these table to be locked a long time (a few sec. max), and the backup of db_name_6 is long (~2-3mn) but it supports the lock). So if I flush the logs each time, not only I'll may have little pieces of logs, but I can't see how to use these to recover a slave. I was thinking to filter these little log files in order to rewrite a correct one but is it possible to do the inverse of the mysqlbinlog command?

Hi,
I have had the same problem running mysqlhotcopy on the MySQL
installed with Woody. I think there is some problem with the
client library while it tries to parse the my.cnf file causing
a segmentation fault. I'm not sure if the problem is inside DBI
or the MySQL libs.
A quick solution is to remove the
mysql_read_default_group=mysqlhotcopy clause from the connection
string:
my $dbh =
DBI-connect(dbi:mysql:$dsn;mysql_read_default_group=mysqlhotcopy,
$opt{user}, $opt{password},
{
RaiseError = 1,
PrintError = 0,
AutoCommit = 1,
});
becomes:
my $dbh = DBI-connect(dbi:mysql:$dsn,
$opt{user}, $opt{password},
{
RaiseError = 1,
PrintError = 0,
AutoCommit = 1,
});
This loses the ability to use dedicated mysqlhotcopy sections
in your config file, but at least gets around the segfault.
regards,
Martin

Question / suggestion re: mysqlhotcopy
Hi All, Apologies if this has been done to death previously, but would it be sensible to indicate in the MySQL documentation that the Perl mysqlhotcopy script only appears to work on the Linux platform? (Or, more accurately, doesn't work on the WinXP platform, I have no idea about other platforms) At least, so it appears when attempting to get it to work on WinXP using ActiveState Perl 5.8. It appears the getpwuid function is unsupported in the Win32 implementation. Alternatively, if there's a known work-around, I'd love to hear about it, and maybe that should go into the documentation instead?

RE: Question / suggestion re: mysqlhotcopy
Thanks Paul! Much appreciated. I'm sure this will be of help to others, particularly because to WinXP Perl neophytes like myself, you only get to find out mysqlhotcopy.pl won't work because of the getpwuid function after you go through solving how to get DBI.pm installed (which turned out to be relatively easy by PPM, of course, but finding THAT out wasn't 2nd-nature to a newbie like myself), because that's what falls over first, since it doesn't seem to be distributed with the ActiveState Perl 5.8 package.

Problem with mysqlhotcopy version 1.17 when using --record_log_pos
Description:
With mysqlhotcopy version 1.15 (from MySQL-3.23.49-1) I used
to do like this:
mysqlhotcopy --user=root --password=foo -q --allowold
--record_log_pos backup.log_pos db1 db2 backup $TMPDIR
After upgrading to MySQL-3.23.55-1 and thus mysqlhotcopy
version 1.17 the same command gave this error:
DBD::mysql::db do failed: Not unique table/alias: 'log_pos' at
/usr/bin/mysqlhotcopy line 437.
The problem is that line 311 now adds backticks around
database and table names:
my @hc_tables = map { `$db`.`$_` } @dbh_tables;
This is not taken into account at line 422 where $table comes
directly from $opt{checkpoint} or $opt{record_log_pos}:
unless ( $hc_locks =~ s/$table\s+READ/$table WRITE/ );
The resulting lock-command becomes:
LOCK TABLES `db1`.`table1` READ, `db2`.`table1` READ,
`backup`.`log_pos` READ, backup.log_pos WRITE
How-To-Repeat:
Try issuing the command
mysqlhotcopy --user=root --password=foo -q --allowold
--record_log_pos backup.log_pos db1 db2 backup $TMPDIR
where the database that the log_pos is recorded in is also in the
list of databases to backup.
Fix:
Fix documentation so it doesn't say
The name of the log-pos table should be supplied in database.table
format.
but
... supplied in \`database\`.\`table\` format.
Or better, add this fix (sorry about my Perl - I know it is
bad):

mysqldump or mysqlhotcopy?
Greetings, I would like to set up cron jobs on my servers to make backups of my databases: 1. The reference manual recommends mysqlhotcopy over mysqldump. Any opinions? 2. What format does mysqlhotcopy save in? sql files? csv? 3. Anyone else doing this with cron? I'd like to see a sample command.

mysqlhotcopy segfaults with perl 5.8
mysqlhotcopy always worked fine with perl 5.6.1 (debian woody), but i had
to upgrade to perl 5.8 and now it croaks and dies with a segfault.
the problem exists only with mysqlhotcopy; other db-connections with
perl 5.8 and DBI/DBD::mysql are no problem.

Anyone of you know how to recovery database point-in-time? you cannot use mysqlhotcopy to back up InnoDB type tables. Only the .frm files are in the database directory, while the data is in ibdata files. mysqlhotcopy does not copy ibdata files or ib_logfiles, and if it would do that, the copies could be corrupt because of writes the database meanwhile does to these files. 4.8.6 mysqlhotcopy, Copying MySQL Databases and Tables mysqlhotcopy is a Perl script that uses LOCK TABLES, FLUSH TABLES and cp or scp to quickly make a backup of a database. It's the fastest way to make a backup of the database or single tables, but it can only be run on the same machine where the database directories are. The way to backup InnoDB tables is to use mysqldump, or InnoDB Hot Backup (a non-free tool). Hot Backup prints the binlog offset corresponding to the backup, and you can do a point-in-time recovery using the binlog files as explained at http://www.innodb.com/hotbackup.html. I think there is currently no mechanism to know what is the binlog offset of a dump taken with mysqldump. Blocking all activity in the server with table level locks is a way to force some binlog offset to your dumps.

There is nothing fancy in the my.cnf file - I have the default configuration for mysqlhotcopy: [mysqlhotcopy] interactive-timeout Any ideas? Does anyone has had such problem? It's not critical, but it's strange.

Mysqlhotcopy error
I am looking into using the mysqlhotcopy.pl script to back-up my databases. When I try to run it, I get the following error: The getpwuid function is unimplemented at C:\mysql\scripts\mysqlhotcopy.pl line 79. I'm not familiar enough with perl to even begin debugging the script myself.. Does anybody recognize this symptom and know whether I'm missing a perl module or something easy like that?

help with mysqlhotcopy
I was wondering if someone could help me out with the syntax to use mysqlhotcopy to backup a database to a tape drive ( /dev/nst0 ). I've tried a few variations of the command but with no luck so far. The mysql server is running on RH 7.2 and the DAT tape drive is on that same machine. Any help would be greatly appreciated.

Go to this URL, http://www.mysql.com/doc/m/y/mysqlhotcopy.html It suppose to do the backup to a folder not on a DAT tape. You can write small shell to first backup your database in a folder and second use tar command to copy the folder on your DAT tape.

mysqlhotcopy broken ???
It appears the v4.0.1 mysqlhotcopy perl script has been modified and broken.
When using cp for the backup it's passing a null value for the file(s) to be
copied. Below is a session clipping of an execution with --debug turned on:
# /u02/mysql/mysql-4.0.1/bin/mysqlhotcopy test_myisam --allowold --debug
Using copy suffix '_copy'
Filtering tables with '(?-xism:.*)'
$VAR1 = [
{
'tables' = [
'test_myisam.incidents'
],
't_regex' = '.*',
'src' = 'test_myisam',
'raid_dirs' = [],
'index' = [],
'files' = [
'incidents.MYD',
'incidents.MYI',
'incidents.frm'
],
'target' = '/u02/mysql/data/test_myisam_copy'
}
];
Existing hotcopy directory renamed to '/u02/mysql/data/test_myisam_copy_old'
Locked 1 tables in 0 seconds.
Flushed tables (test_myisam.incidents) in 0 seconds.
Copying 3 files...
Executing 'cp -p /u02/mysql/data/test_myisam_copy'

Unlocked tables.
Deleting previous copy in /u02/mysql/data/test_myisam_copy_old
mysqlhotcopy copied 1 tables (3 files) in 0 seconds (0 seconds overall).
Any fixes for this?

mysqlhotcopy regexp problem with 640 and more Databases
Description: When using mysqlhotcopy 1.15 for database backups with --regexp='.*' and having 640 or more Databases produces the following error: DBD::mysql::db do failed: File '/lvol1/mysql/data/mydatabase/mytable640.MYD' not found (Errcode: 24) at ./bin/mysqlhotcopy line 432. The file exists though. If i create a table alphabetically before the one with the error, then the next time i use mysqlhotcopy it also produces the error on the next table alphabetically before, but always on the 640. table. Line 432 of mysqlhotcopy 1.15 is: $dbh-do(LOCK TABLES $hc_locks); Commenting that line makes the error go away. mysqlhotcopy also works fine if i use it only on the single database where the error occurs with --regexp='mydatabase.*' since there are less than 640 Tables then.
