I need to make a good, reliable back up of our WinXP Pro SP2 home machine. The C:\ HD is a 120gig, 49 gigs free space (and I haven't done any HD housecleaning in a while). We have an 60gig EXternal HD, the E:\ drive which hold the contents of my prior machine which took a total dump last summer. I would like to get a second EXternal HD to use solely as a backup data storage drive, and write subsequent, incremental backups to that. Most of the times I've tried to write a backup to either the DVD or the CD, I end up with some silly sw error at the very end of the session - PLUS, it takes forever and needs a human to sit there and feed it disks. Money is a big consideration budget-wise, yet it also makes NO sense to spend any money on a el crappo EXternal HD and just have it go bad later. So, mfg rep is also a big consideration. In looking at newegg's site, I noticed the following - which gives me some concern: Oh, also..... I have never, ever been able to 'get' the concept of "ghosting" or "imaging" a drive. Maybe it's a semantics issue, I don't know; but my brain comprehends two things in this regard - either a backup is the backedup data in compressed form, or an additional drive is an exact copy of another and its data. IOW, the data is on the backup drive in compressed form and in write sessions, or it is there in an exact duplicate form. The "ghosting" and "imaging" of a drive throughs my feeble brain for a loop ;( So..... any thoughts as to which mfg(s) I should look for especially considering the 'no DOS drivers' aspect?
