Yeah, well. It won't work no matter how you try to do the target dedupe. The way bareos writes the data to the disk storage is in essence the same way as it does it on tape, and that makes it almost impossible to dedupe the data.
So you might as well save yourself the time and effort to try it out, and just use GlusterFS or something similar instead. Or maybe just a huge JBOD. There's actually a RFE for it here: https://bugs.bareos.org/view.php?id=268 /tony 2015-05-21 10:08 GMT+02:00 Ronny Egner <[email protected]> : > Hi, > > > It looks like for the time being my only choice is to go with my other > >option which was to buy another 32TB raid array and LVM across it. > > > I would say that.
