The primary advantage of the virtual autochanger is you can more easily use removable hard drives or other temporarily-connected storage. For fixed storage, I'd say it's not worth bothering - but I'll give this warning. Backups are for data you care enough about to keep in at least 2 separate physical (not virtual) locations. Anything attached to the backup system is not separate. In the event of a system compromise where the intruder deletes files: If the backups are in any way, shape or form able to be deleted without manual physical intervention (ie, on mounted drives, or even on connected but not mounted drives(which can be mounted for formatted)), then you should expect that they _WILL_ be deleted. I know of several organisations who have found this out the hard way. One had set sets of disks online used in GFS rotation (all three got wiped by a particularly nasty script kiddy who took down an ISP webserver holding about 2500 websites.) Others have had backups wiped via accidental "rm -rf /" events. Not all of them managed to stay in business. ALL of them suffered major reputational damage and incurred costs trying to recover. The same thing applies if all your backup tapes are in the changer (only the tapes being currently written should be accessible, the rest should be in a fire safe), but at least wiping them takes longer. ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
