I'm guessing you are worried by a comment I made at folkinfo, Aziz.

The situation is that my ISP hold the data, and we try to take a weekly backup mostly just in case they did a runner, got hit by an airoplane, decided we werne't fit to be hosted and ditched us without letting us have our data back, etc..

The ISP themselves should not be (and I don't think they are or I would not use them) so incompetent as to loose our data but even if that happened we have got some cover although maybe we would loose a few days.
