Hi, I have a few questions regarding backing up files. I currently do not have a proper backing up 'system', i.e. I only drag and drop files which are important on to an external hard drive and this is quite random. I am considering implementing a RAID0 system on my PowerMac G5 and installing an eSATA card to connect to an external drive with high bandwidth. However, I am unsure of the best way to backup?! If I have RAID0 and purchase a 1TB external drive (connected by eSATA) can Time Machine do all the hard work? By this i mean can it create a completely mirrored drive or will it back up only the user files and not the system files? Also can you set Time Machine to backup on the fly or will it only do it at set intervals? If Time Machine can't sort this fuss out, is there another program which can do it hassle free and manage backing up efficiently in the background like Time machine? It is just that with RAID0 I fear a drive failure and would like the simplicity of just reinstalling the contents from a mirror if a failure occurred? Thanks for any help.
