The Scripts

Scripts are located in /root/backup.

Nightly backup

The nightly back copies everything to merple. It:

1. mounts /mnt/backup to //merple/backups.
2. iterates over the ms sqlserver databases, backing them up to /mnt/backup/sqlserver/$DAY
3. iterates over the mariadb databases, backing them up to /mnt/backup/mysql/$DAY
4. copies the apache config to /mnt/backup/apache2-config/
5. copies the ssl config to /mnt/backup/ssl-config/
6. finally, using rsync directly because smb has no compression and it's too slow otherwise, it copies /var/www/html directly to merple:/srv/backups/websites/

Other backups

In order to give Matt the ability to roll back any damaging database changes (or recover historical data), we back up the MS Sql Server every 4 hours, every Monday and on the first day of the month. These go to /var/opt/mssql/data/backups/$BACKUP_FOLDER and Matt can restore from them using Sql Server Manager.
