logic of storing your file on external drive vs Cloud. (Home PC usage)

a TB physical storage vs Cloud's- how do you see pros and cons (for home use).

when would you be content with just an external drive and when would you go for cloud storage?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Local external storage is fast, and you can buy quite a bit for a very reasonable price. The main downsides to it are loss of the storage due to disaster, theft, or other accidents.

Cloud storage is far away and theoretically is protected against disasters. It's not cheap to buy and maintain cloud storage and it's "slow" to get a lot of data there, but once it's there, you should be good.  No matter what happens at your home, you data is OK.

Downsides to cloud storage is price, speed, will the company go out of business, are they really doing their due diligence security-wise.

I personally use a combination. I have Macs and use Time Machine to back up to local external storage pretty much everything. I also use a Cloud backup to just back up my documents and other important data that would be hard to reproduce should I have a disaster of some kind.

Some combination is better than either one alone. It's worth the extra set-up time to make sure they are both relatively automatic - disaster likes to strike when you're least prepared for it.

The Crashplan family of products allows you to have both local and cloud backups (but I haven't gotten around to setting this up for myself, yet). Since cloud storage is slower, more expensive, and has its own set of failure risks (company has a security breach, goes out of business, or radically changes its business practices), you may find yourself using two of them. An external disk or a second computer at your home or office holding backups is not protected from localized disasters, such as fire or theft, but will allow you to make a faster recovery from smaller incidents like a disk or other hardware failure. It's practical to make image backups to local disks at home, not so practical over WAN links.

I think I'm mostly just echoing what jhyiesla had to say....

OK.. and cloud makes sense only when it can sync, right? (otherwise, it will be too much of upload each night?)
Need More Insight Into What’s Killing Your Network

Flow data analysis from SolarWinds NetFlow Traffic Analyzer (NTA), along with Network Performance Monitor (NPM), can give you deeper visibility into your network’s traffic.

Yes, you want a backup system to be sensible about not using bandwidth for data which is already backed up. It could be called incremental rather than sync. Having older versions available is always a plus, too, since sometimes we make mistakes in editing or deleting.
personally - i don't want my data on the net, so i don't use it; only local external drives
Nobus: please tell me you have a way of storing the drives onto which you backup locally that involves getting them out of your house or office to an alternate location. If the copy stays local, i.e. in the same building with the live data, then there are many experts who would say it is not really backed up.
that is for business backups, jmcg - not for personal , or home use
if my house burns down - i have no need for my data, how important my pictures may look now
feel free to have a different opinion; but MY DATA does not go on the web
Sync'ing is great if that's what you want/need. The thing I don't like about some cloud systems that basically sync is two-fold. One is that many of these systems create their own folder on your computer to which it then syncs. So unless you by default store your data in that folder you have to copy it there and then you have two copies on your computer taking twice the disk space. The other thing I don't like is that if you happen to delete it on your computer it deletes it in the cloud so it's not much of a back up.  

I use a system (iDrive) that is a back up. I tell an agent on my computer to back up already established folders at certain intervals. The first time is a full back up and from then on it only backs up changed files. And it will keep multiple versions in the cloud so that I can get back to some previous version or even a version that was deleted for a time.
I have to say I lean more towards Nobus view of the Web when considering personal data, particularly after the T&C gotchas that Google, MS and others have tried to get through in the past. I backup nightly to a local server and once a week all 7 days go to a different site which maintains about 90 days of 'volatile' files and at least one copy that I don't delete at all - but its all encrypted and I own the hardware.
i find it revulsing that facebook, google and such are spying on us - without telling so, and using (= selling) this data to others...
I never fill surveys for the same reason - no monetisation without compensation!
you don't have to do anything - they follow all your moves on the net...
true,  the illusion of control is merely comforting
