|
||
backup to <span class="strong"><strong>remote</strong></span> hosts. Though this sounds like a nice feature
|
||
(<span class="emphasis"><em>"Backup my notebook to the server now."</em></span>), in my opinion it is a
|
||
bad idea to backup to a remote host.</p><p>But as more and more people requested this feature, it was implemented,

so you have the choice whether you want to use it or not.</p><div class="section"><div class="titlepage"><div><div><h4 class="title"><a name="_reason"></a>Reason</h4></div></div></div><p>If you want to backup <span class="strong"><strong>TO</strong></span> a remote host, you have to loosen security on it.</p><p>Imagine the following situation: You backup your farm of webservers <span class="strong"><strong>TO</strong></span>
|
||
a backup host somewhere else.
|
||
Now one of your webservers which has access to your backup host gets
|

compromised.</p><p>Your backup server will be compromised, too.</p><p>And the attacker will have access to all data on the other webservers.</p></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a name="_doing_it_securely"></a>Doing it securely</h4></div></div></div><p>Think of it the other way round: The backup server (now behind a

firewall, not accessable from outside) connects to the
|
||
webservers and pulls the data <span class="strong"><strong>from</strong></span> them. If someone gets access to one
|
||
of the webservers, this person will perhaps not even see your machine. If
|
||
the attacker sees connections from a host to the compromised
|
||
machine, she will not be able to log in on the backup machine.
|

All other backups are still secure.</p></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="_incompatibilities_and_changes"></a>Incompatibilities and changes</h3></div></div></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a name="_versions_0_9_and_1_0"></a>Versions 0.9 and 1.0</h4></div></div></div><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">
