Hello all, I have a VANTEC NexStar HX4R running 4x 2TB WD Reds connected to my Mac Mini, set to RAID 10 (1+0). I've partitioned the drive, leaving 1TB for TM to backup my Mini, and 3TB for media. Others (and numerous Google searches) advise against using RAID as a backup. Fundamentally, I get why - but given my usage, does anyone here have an opinion on whether I should still worry about backing up my RAID as well? My Mini is essentially a further backup for the MBP and MBA in the house, along with two of the kid's iPads. Nothing unique is found on the Mini - all essentials (family photos etc.) are originally stored on the two laptops. Where the Mini does have unique data, it's media mostly - ripped kiddies DVD's etc., setup through Plex, feeding the other devices. It's also connected to the 50" Plasma in the lounge, for viewing the said movies. They way I see things, using RAID1+0 in this instance, is seeing a TM that is backing up a Mini that has critical data already found on other devices - devices which are uniquely back-upped themselves using TM to different externals. Therefore, it's surely unlikely that both Mini AND RAID were to fail at the same time? And even if that were to happen - the original data could still be recovered from the laptops or their TM backups? [In the case of my MBP - I have both TMs AND cloned disks as well] Any thoughts on this? I kind of feel forking out for another 4TB external, to backup my RAID is kind of overkill, given my use scenario... AFAIK, most of the advice against using RAID as a backup, is where critical data is only being stored on it - which is not the case here? Suggestions/opinions would be welcomed!
