My current strategy; - Backup criticals to CrashPlan Central (100GB of docs/pictures and itunes) - 500GB G-Drive Mini: 200GB Bootable Superduper partition 300GB of my Video library My g-drive mini is maxed out, and i last week ordered a massive hard drive expansion solution. -Cremax ICY DOCK MB662UEAB-2S FW800 - 2x Hitachi HDS722020ALA330 3.5 inch 2TB Yes, 4TB is overkill, but the 2TB drives were £95, and the 1TB drives were £60, so i had to give in. I will not be setting these up as RAID 1 (as its not a backup strategy, and i dont demand rapid recovery time), nor BIG or RAID0 (as im not insane). This i will be using JBOD or "independant" drives (as some call it). The primary purpose of these drives is to increase my storage capacity for my rapidly growing media library, however,i would also like to improve the robustness of my backup strategy, and am not sure ho best to do it. Of the 2 drives in the enclosure, call them drive A and B, im trying to figure out the best strategy for backup. Im thinking, store all my files on drive A. And then maybe getting some software to copy drive A onto B. Firstly what would be best for this. Secondly what partitioning would i need. Do i need to partition drive B, into (Backup of Drive A : Free space for general storage), theres no way I need the full 2TB of 'B' for my backups of my stored media library.
