How could it possibly be up to date if there has been a commit since the last time it was updated? Because the commit came from my WC. My WC was up to date before the commit, and the only things that change have been in my WC already, so there is no possible way my WC can not be up to date. That assumption is wrong, I guess. As far as I know, commit hooks can modify the commit. (This behavior is discouraged, but nevertheless it is possible.

Hi, Von: Andy Canfield [mailto:andy.canfi...@pimco.mobi] And make /backup a separate filesystem, preferably on a different host or some disk storage that runs independently from the host. In Linux a separate filesystem is often another partition on the hard disk, and thus not to be trusted too much. For safety an external hard disk, flushed, should be good enough. No need for an entire other host. Yes? Only if the external hard disk is only connected via fibre optics cable (SAS or similar) instead of copper cable. Electrical surges and short-cirquit faults tend to kill the server and the attached hard disks at the same time.

Electrical surges and short-cirquit faults tend to kill the server and the attached hard disks at the same time. Only if the disk is connected to a different power source, otherwise it doesn't much matter whether it's killed via data cable or power supply. (Also, this will in most cases only kill the drive electronics; there is still the possibility to have the driver platter to be installed into another drive, by professional recovery services.) But the simplest ist to disconnect the external drive and to use two or three in cycles (if that hadn't been mentioned here), and take the others home or another location different from the servers's.
