On-site backup

At 23:00 an on-site copy of all databases and webserver files are saved in this location:

/var/backups/wmi/lessema.wikimedia.it

Note: the permissions of the parent directory MUST be set to 750 root:root to keep the backups not accessible by untrusted users (note: the www-data is considered not trusted).

The execution time can be edited with

crontab -e

Note: the backup script prevents duplicate executions caused by daylight saving or standard time changeover.

The backup instructions can be configured here:

/opt/micro-backup-script/backup-instructions.conf

This is the source code of our dummy backup script in use:
