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.

Off-site backups

The same script that does #On-site backup also push the backup on server ⚙️ horror in this position:

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

The users are authorized to access this location:

The exact data retention is documented on server ⚙️ horror.
