Overview

A system administrator with #Server access and enough privileges can login in the server via SSH.

All recent backups are here:

/var/backups/wmi

Older copies can be obtained adding a numeric suffix. For example the 2-days-old backups are here:

/var/backups/wmi.2

Note that all sub-directories can be accessed only if you are its dedicated user.

For example all of these are owned by the user lessema:

/var/backups/wmi/lessema.wikimedia.it
/var/backups/wmi.1/lessema.wikimedia.it
/var/backups/wmi.2/lessema.wikimedia.it
/var/backups/wmi.3/lessema.wikimedia.it

So to get these copies do something like this:

rsync lessema@horror.wikimedia.it:/var/backups/wmi/lessema.wikimedia.it .

If it does not work, make sure to have the right #Server access privileges.
