Thanks go to the following people (sorted by alphabet): * Alexey Maximov - for finding return-value and shell limitation bugs * #cLinux IRC channel on irc.freenode.org - for testing and debugging (those I mean should know ;-) * Daniel Aubry - for reporting many hints * John Lawless - A lot of patches and some very interesting discussions. * Markus Meier - for finding a really simple solution for choosing the right backup to clone from: Make it independent of the interval, simply choose the last one created.
