External HD for Backup RAID

[cielblue]

Hello,

I am thinking about buying a HD for a full system backup and all files. I am worried about getting such a big HD and having it fail, thus loosing years of data. Is there any redundancy in a 1TB drive does partitioning help? What if the entire drive fails or are there multiple drives in those external hd? I need a reliable backup system for music, photos of child, that will last years.

any advice would be appreciated and also
I want to be able to use the HD with both formats, pc and mac...what should I format with or is that a good idea?

thank you

If you're really worried, then get two or more ext HDs. If you want to use it with PC and Mac, then you have to partition it as Time Machine nor any other backup utility supports other formats than HFS+ and that is not readable in Windows. FAT32 is readable by both OSs without any extra steps but you can quite easily add support for NTFS in Mac
