I wrote about Galera about 1.5 years ago: State of the art: Galera – synchronous replication for InnoDB. It was about the 0.7 release, which was more like a proof-of-concept release (though Galera’s developers may not agree with that ) with some serious limitations (like using mysqldump for node propagation). The Galera team heard my […]

If you do incremental backups, it’s strongly recommended that you upgrade to this release.

We’ve written about replication slaves lagging behind masters before, but one of the other side effects of the binary log being serialized, is that it also limits the effectiveness of using it for incremental backup.Â Let me make up some numbers for the purposes of this example: We have 2 Servers in a Master-Slave topology.

I am happy to announce next build of our backup tool. This version contains several bugfixes and introduces initial implementation of incremental backup. Incremental backup works in next way. When you do regular backup, at the end of procedure you can see output:
The latest check point (for incremental): '1319:813219999'
>> log scanned up to (1319 813701532)
Transaction log of lsn (1318 3034677302) to (1319 813701532) was copied.
090404 06:03:29 innobackupex: All tables unlocked
090404 06:03:29 innobackupex: Connection to database server closed
innobackupex: Backup created in directory '/mnt/data/tmp'
innobackupex: MySQL binlog position: filename 'db02-bin.001271', position 247627478
090404 06:07:58 innobackupex: innobackup completed OK!
innobackupex: You must use -i (--ignore-zeros) option for extraction of the tar stream.
which gives start point 1319:813219999 for further incremental backup. This point […]
We are coming with next version of xtrabackup – online backup solution for MySQL 5.0 / 5.1 and InnoDB standard version, plugin modification and XtraDB. We still consider it as alpha version, though it shows perfect stable results in our tests. Let me address two often asked question about xtrabackup: 1) Does it work only […]
For long time as main backup solution for MySQL on Linux we have been using LVM snapshots. Performance concerns from performance critical envinronment caused us to do LVM performance research which showed horrible results forcing us to look at more performing alternatives. Innodb Hot Backup is a good working solution but it is not Open […]
