Hello,

I'm folloing the instructions from the "MySQL Enterprise Backup 3.12 User's Guide - Chapter 6 Using MySQL Enterprise Backup with Replication"

I'm able to take the successful backup from master & copied it over to the slave. On slave when i'm trying to prepare the backup for restore using apply-log option I'm getting an error as listed below,



[root@mysqlslave x]# mysqlbackup --backup-dir=/usr/x/mysql_backup/ apply-log

Could someone guide me if i'm missing anything here...

ERROR 1146 (42S02) During Database restore. Ver: 5.1.54-community (no replies)

I have a MYSQL server with multiple databases, I use a batch file + task scheduler to back up my databases on daily basis. During restore of one of the database using Mysql Workbench on a new server with same MYSQL server version (5.1.54-community) I encountered ERROR 1146 (42S02) at line 18819: Table 'DB2.rhicd5_hic_desc' doesn't exist
This is wired as DB2 is not the database I was restoring. Somehow DB1 (database being restored) has reference to 'DB2.rhicd5_hic_desc' (a view from second database on my old server).
Command to backup database:
C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqldump.exe" --user=%dbuser% --password=%dbpass% --databases %db% > "%db%.%backupdate%.sql"

Someone please help me understand why this is happening and how can I do a clean backup.

Hi all,

We are running MySQL 5.5 on Solaris 10 and are looking to migrate to CentOS. I am looking whether we can run mysqldump from Solaris and restore the backup file to Linux (on the same version 5.5) Whether there will be a problem during the restore. If not, what would be the best way to do such a migration.

thank you

ndb_restore fails (no replies)

Hello,

I've been trying with intermittent success to restore my ndb_backups to a new cluster.

We have a 6 NDB node cluster with 3 API nodes. When I run an ndb_restore, usually the first 2 or 3 node backups get pulled in without issue. But the 4th and 5th node fail with the following error:

Temporary error: 266: Time-out in NDB, probably caused by deadlock
Temporary error: 266: Time-out in NDB, probably caused by deadlock
Retried transaction 10 times.
Last error266: Time-out in NDB, probably caused by deadlock
...Unable to recover from errors. Exiting...

Strangely, sometimes I can simply rerun the backup and it finishes without error.

I'm hoping someone knows what kind of tweaks I can make to my configuration to optimize this process. Here are my version numbers and configs:

What is the best way to do a clean install of MySQL 5.6 with data from mysql 5.5.46?

My computer (running mysql 5.5.46) just broke down (actualy it started to burn, but that is another story). So I had to buy a new one and decieded to take the chance to upgrade to the newest Ubuntu-Version which comes with MySQL 5.6.

Unfortunatly I failed completly at restoring the old data - i've several backups of the MySQL data-folder and all files from the old PC are undamaged as well. But whenever I try to restore the old ibdata-files the MySQl server just crashes.

So before I try it again: What is the best clean way to do this? How can I restore my old data-folder?

I use MYSQLDUMP for backup purposes have have been doing so for years. I just realized that for one table it is only backing up the first record, then goes on to the next table. No error, no message. I didn't know it was happening. Other tables have always worked, or so I thought. Now I have to check every one. What is happening and how do I fix it?

Importing backups. (10 replies)

Hello,

I run a small minecraft community and therefor use mysql (most used for this game). And with running communities I need backups etc,

Now the issue I have is that importing files is extremely slow. Importing a self contained file takes an insane amount of time. 4.4GB file is running for over 4 hours as I speak.

now you may think it's a slow internet connection, but I don't use a network for this. The file is already on the machine. This is no slow machine either, it's dedicated to do very low amount of things, and mysql does not seem to do anything as it's averaging 0.1% cpu usage. Disk (SSD) usage is a bit higher peaking at about 50 MB a second.

I do use mysql workbench on a Windows machine, with an Intel SSD and 32GB, CPU Intel e3 1270v3

Is there any reason this is taking such an insane long amount of time?

Please be easy on me, I just do this to provide kids a good time for free without any real knowledge of mysql :)
