MySQL Enterprise Backup: parallel config & backup n restore results.
Employee +0 Vote Up -0Vote Down

In this post I go into some performance metrics and time spent on using MySQL Enterprise Backup instead of mysqldump, and seeing how far I could go with some parallel configuration.


It’s on an old laptop:

MariaDB Database Disk snapshot backups on Windows
+4 Vote Up -0Vote Down

Using disk snapshots to perform MariaDB backups has become more and more common, but this seems to have been limited to Linux and Cloud environments. There seems that there has been a notion that Snapshots cannot be done on native Windows, the way we can do snapshots using LVM on Linux for example. This is actually False, if you use the NTFS filesystem snapshoting is built in and has been so for a long time, the base for it is the Volume Snapshot Service (VSS) which was introduced as far back as Windows XP.

Using Snapshots to backup on Linux or Windows works well, …

how MySQL engineering broke the backups
+0 Vote Up -0Vote Down

MySQL has exceptional track of record by introducing minor fixes that cause major breakages. Though usually I could blame naiveté of engineers, who did not really ever have to deal with production implications, but lately I can start sensing various business implications against open-source offerings.

As an original author of mydumper I really cannot get out of my mind that 5.5 and 5.6 metadata locking changes are there to screw with anyone who is building a backup solution using stable snapshot views of …

Backing up full server instance using MySQL Enterprise Backup
Employee +0 Vote Up -0Vote Down


MySQL Enterprise Backup(MEB) takes fast, consistent backups of MySQL server data, and helps in restoring the server to source server's data at the time of backup. But most of the times it is as much important to have same source server's state(server configuration like server global variables, plugins), as data. As backups become more frequent, server variables modified, plugins added or removed, it is very difficult to keep track …

TokuMX Hot Backup – Part 3
+0 Vote Up -0Vote Down

Last week I described TokuDB’s new Hot Backup feature.  This week we are going to briefly discuss the same feature, but as it was added to TokuMX, our version of MongoDB.

Since the Hot Backup library is essentially a shim between MySQL and the Linux kernel, intercepting file system calls for the life of the process, it should be easy to add this to any other system, including TokuMX.  Indeed with our addition of transactions and logging to TokuMX we can gain a consistent backup of any data set at any time.

Skip Unused Pages with MySQL Enterprise Backup 3.9.0
Employee +2 Vote Up -0Vote Down

The views expressed on this blog are my own and do not necessarily reflect the views of Oracle.

There are database usage patterns, where tables grow big at times and many rows are deleted from them later. InnoDB does never shrink a table space. In these cases we can end up with big data files, which contain a lot of unused pages. It is a waste of disk- and I/O- resources to back them up.

Users have manifold requested that MySQL Enterprise Backup does not back up unused InnoDB data pages. Some want smaller backups, some want less I/O, some want shrinked table spaces.
