ibdx

Use case

• backup/restore mysql InnoDB tables in an easy way

Setup

From pypi

pip install ibdx
or
pipx install ibdx (recommended)

From source

git clone https://github.com/Grvzard/ibdx.git
cd ibdx
pip install .

Usage

ibdx --help

Take care: There seems to be an incompatibility between mysql and mariadb. Make sure that ibdx works between the same db system.

Example

Let's say we have following tables: [ logs_2023_01, logs_2023_02, logs_2023_03, logs_2023_04 ]

ibdx backup -u user -p password -h localhost --db test1 --tables logs_2023_% -f logs.2023.zip [--datadir /mysql/datadir]

ibdx restore -f logs.2023.zip -u user -p password -h localhost --db test1 --tables logs_2023_% [--datadir /mysql/datadir]

When the mysql server is running in Docker, the --datadir option is required.

Script Workflow

backup:

1. mysql> FLUSH TABLES test1 FOR EXPORT; (tables are read locked)
2. backup the .ibd (and .cfg) files.
3. mysql> UNLOCK TABLES;

restore:

1. (optional) mysql> CREATE TABLE test1;
2. mysql> ALTER TABLE test1 DISCARD TABLESPACE;
3. copy the .ibd (and .cfg) files to the mysql-server's datadir
4. mysql> ALTER TABLE test1 IMPORT TABLESPACE;
