7 Backing up an RMT server #

Revision History: Repository Mirroring Tool Guide

This chapter explains how to create a backup of your RMT server and how to restore from it.

7.1 Creating a backup #

This procedure details how to create a full backup of your RMT server. It is assumed that you have an external disk or network share mounted in /mnt/backup that serves as a target for the backup.

Change to the backup directory.
```
# cd /mnt/backup
```
Create a file containing a dump of your SQL database. You need to provide the password you set for the rmt database user during the installation.
```
# mysqldump -u rmt -p rmt > rmt_backup.sql
```

Optionally, create a copy of your mirrored data.

# mkdir repos
# rmt-cli export repos ./repos/

7.2 Restoring a backup #

This procedure details how to restore your RMT server from a backup created in Section 7.1, “Creating a backup”. It is assumed that the backup is mounted in /mnt/backup. It is also assumed that you are restoring the server on a newly installed SLES.

Install and configure the RMT server as described in Chapter 2, RMT installation and configuration.
Go to the backup directory.
```
# cd /mnt/backup/
```

Use mysql to remove the newly created database and import the data.

# mysql -u rmt -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
[...]

MariaDB [(none)]> DROP DATABASE rmt;
Query OK, 14 rows affected (0.84 sec)

MariaDB [(none)]> CREATE DATABASE rmt;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> use rmt;
Database changed

MariaDB [rmt]> source rmt_backup.sql;
[...]

MariaDB [rmt]> quit

Optionally, import the exported repositories.
```
# rmt-cli import repos ./repos/
```
Synchronize your data and update your repositories.
```
# rmt-cli sync
# rmt-cli mirror
```
