Backing up users and privileges in MySQL

There are two simple ways to backup only the users and privileges in MySQL:

1- Using mysqlpump utility (as create user and grant statements):

[shell ~]$ mysqlpump -uUSER -p --exclude-databases=% --add-drop-user --users > /tmp/pump-all-users_privileges-timestamp.sql
Dump completed in 1364 milliseconds

Sample output:

[shell ~]$ head /tmp/pump-all-users_privileges-timestamp.sql

-- Dump start time: Sun May 13 23:30:49 2018

Restore a table / database from full backup – Yet another way

Restore requests are common and so are the restores of specific entities: a database, or one or more table(s). This has been discussed a lot and we have plenty of tools and solutions already available.
In this blog post we will cover an interesting solution that I came across when I received a restoration request from a client with a specific scenario.

The scenario? Well, the client was on a Windows server with 400GB of mysqldump and wanted to restore a table.

As Linux players we already know of some tools and techniques to export a table or database from mysqldump – for example, using sed command or using the script mysqldumpsplitter (based on sed itself). But on Windows we are powerless by not being able to use sed (we’re sad without sed.) Also, there was no cygwin to ease up the pain.

We had to come-up with a solution that works on …

How to Restore MySQL Logical Backup at Maximum Speed

The ability to restore MySQL logical backups is a significant part of disaster recovery procedures. It’s a last line of defense.

Even if you lost all data from a production server, physical backups (data files snapshot created with an offline copy or with Percona XtraBackup) could show the same internal database structure corruption as in production data. Backups in a simple plain text format allow you to avoid such corruptions and migrate between database formats (e.g., during a software upgrade and downgrade), or even help with migration from completely different database solution.

Unfortunately, the restore speed for logical backups is usually bad, and for a big database it could require days …
