I've never used the available backup software out there and am having a hard time finding information on how they work. I see it's common they create disk volume backups and even bootable backups, but I am looking for a solution for a unique use. I posted earlier on a hardware forum about trying this but didn't get any responses. I think this is more a software questions and appreciate any feedback as to if this would work or if it's a bad idea for a reason I'm not considering. I do HD video editing and am in desperate need of additional storage. I've reached the point where I would benefit from a RAID 0 (stripped) setup--thinking 2x 1TB hard drives. I would like to backup the data but don't want, need, or have the money to get a legit 4 drive RAID 0+1 setup. I don't need real time backups and would prefer to save money with the mirrored portion of this setup by simply doing daily backups. (Plus this way I won't slow down my array if I purchase slower drives for the backup) I would only need to backup the stripped set once a day at most or when needed so I feel this would work fine. I would prefer to sync up the backup in the way an iPhone updates its calendar---that it only makes the recent changes instead of rewriting the whole disk. Does anyone have advice on software that would be best for this application. And also, does my idea make sense? Is there something I'm not considering? thanks, your advice is much appreciated.
