So, at 5 Mbps (avg.?, DSL?), that's, what, 5/8 MBps, so 10 GB should take 163,840 seconds to copy up, or 1.9 days. Best case.<br>
<br>
Oops, sorry, that's up, and residential service is usually asymmetric. So if 5/512 down/up, it's actually 19 days up to back it up.<br>
<br>
Sounds like one would want to be selective about how much goes up, given the durations involved.<br>
<br>
Having been selective ... where does the rest of your data go to be safe?<br>
<br>
Wouldn't an eSata drive, rsync'ed to from everywhere on the net, nightly, be more optimal?<br>
<br>
Or, what am I missing?<br clear="all"></blockquote><div><br>You only need to do it once. After that, only changes are pushed. I'm not sure if it is rsync-like, or if whole modified files are pushed up. But you don't need 19 days for every backup.<br>
<br>Personally, I use a rotating drive hotswap, because I've got more than 100GB. When you consider the cost of SpiderOak ($100/year/100GB), you can buy a new 2TB hard disk and have 20 times that storage. And next year you can replace or add on a new drive (3 or 4 TB?). Every year.<br>
<br>That said, I set my parents up on SpiderOak. They never connected the external drive I gave them. Then the nas I gave them never got turned on after a power outage. So that's one benefit of online backups, anyway. Maybe next year I'll figure out how to get their machines to rsync to my house.<br>
