BitTorrent Sync is an interesting peer-to-peer alternative to DropBox. No middle man. Google "btsync" for more info. [I'm not connected with them in any way, but I've successfully used the service for over a year].
Copy.com, managed by Barracuda, is another cloud storage service that works very similarly to Dropbox, except that you start with 15GB of storage and get an additional 5GB for every referral (compared with 2GB and .5GB for Dropbox). Shared space is also divided among shares on a pro-rated basis, so 1GB shared is spread betweeen the number of people sharing.
If you join from a referral, you also get the additional 5GB, so here's a link to Copy.com. If you use this referral, you'll start with 20GB.
@Brisco66: Copy.com, managed by Barracuda, is another cloud storage service that works very similarly to Dropbox, except that you start with 15GB of storage and get an additional 5GB for every referral...
Very interesting -- I'll look into them. Thus far I've been extremely happy with my DropBox account -- but maybe I'll open an Copy.com account and then use that for the bulk data like huge images and suchlink while keeping DropBox for my smaller, mission-critical work data...
Max, it seems that great minds think alike. I'm not leaving Dropbox either, but found that having Copy.com to back up stuff that I don't want in DB gives me added peace of mind since it provides so much more space than DB. https://copy.com?r=t3Jz1w
I felt in love with cloud storage a couple of years ago and I've happily avoided tons of problems since then. This kind of services are really handy if you work with several different platforms as I do too.
As a fast alternative, you can use a Microsoft or Google email account to get a web browser enabled cloud data storage service -- I discovered some months ago that my old and largely unused Hotmail account provides me some GB of free storage now ;-)
But only some days ago, my smile turned into a sad face when I received a mail in which I was informed about Ubuntu One data storage is going to be closed in a few weeks...
For local backup, I currently have a desktop computer with a RAID1 disk system. It's one of my XP machines so when I get the Win 7 desktop that is going to replace it I will dedicate that computer to local backup. I really should set up a cloud backup system so I have something off site though...
The RAID system has already proven itself. when one of the disks crashed, I was able to copy the data off the good drive (just to be safe), then take it to the local computer guy who installed a new drive and got it synced up for me.
A RAID (even a mirror like RAID1) is NOT a backup! Please don't make the mistake of treating it like one. If you accidentally delete a file it will delete on both. If you destroy the partition or anything else it will mirror it to both drives. If a file gets corrupted it will corrupt both copies when it mirrors it. RAIDs of any type are NOT a backup.
Try out one of the online backup services or simply buy a couple large hard drives and use a program like "create synchronicity" (open source I believe). CS will "mirror" your files (and create new copies of modified files instead of writing over your backup) or it can do simple backups or many other neat tricks.
Also, Dropbox is not a backup either. It's a file sync service. Be careful using it as a backup (even Dropbox says this. It's possible to damage the file on one system and then sync the damaged file everywhere else for example).
Services like this have some of the same characteristics of a system with RAID disks. You get a N+1 copy of each file that you designate, but not what I'd fully call a "backup".
The problem is that if you either corrupt your file(s) or delete them, that change gets dutifully corrupted/deleted on every machine, yielding no good copies anywhere. So, if your machine gets hosed in the right way, you *will* have a good copy in the cloud. However, if you hose it in the wrong way (like with a nice recursive delete that starts in the wrong place), you're still hosed. If someone steals your machine and deletes the contents of your Dropbox, the stuff is apparently gone for good unless you're lucky enough to have one of your other machines *off* the network at the time.
There's an indication on Dropbox's website that their premium Business service has version-control, so it's possible that it doesn't suffer from these types of non-failure failure.
The lesson is -- don't keep your only copy of a file in your Dropbox folder, because it's not "backed-up" against cranial failures. You still need some other type of backup solution to really be protected.
DropBox seems to be a good option for backup. I lost lots of data because I copied in external harddisk and when I moved dont know what happened to hard disk it doesnt come up. Had I copied in DropBox iI still would have that precious data. How about security. Will it get copied and used by anyone.
the onedrive.com is a Microsoft alternative, but it is a very nicely done solution. Maybe it does not have 100% of all the features the other platforms have, but the core ones are there. Plus you have free online Office tools to edit your files in MS office or OpenDocument formats.
As far as I understand they support onedrive on all majour PC, tablet and phone platforms and even xbox. You get for free 7GB, but some of us got 25GB for free permanently due to a promotion for the early adopters.
Also through onedrive.com you can access all files on your other registered PCs (no need to configure routers or firewalls) if they are on.
I think now Windows 8.1 also backs up and sinchronizes some Windows preferences using onedrive.
I did my self IE favorits sychronizing on all of my PCs through onedrive.
Now there is also some kind of documens version history support, but I have not tried that yet.
I was confused- I have Microsoft's "Skydrive" on my machines, although not used much. I was puzzled by "Onedrive". It appears that Microsoft agreed to change the name at the insistence of bSkyb (from the UK), but have also improved the service as detailed in this article "OneDrive vs SkyDrive"
