Restore selected files using a script from Sugarsync, SpiderOak, Dropbox, Carbonite ... or?

shalvors:  Thanks!  I'd figured that much out myself as I have Dropbox installed.  I'm less familiar with using Dropbox as a backup destination.

I still wonder about the others.  There are quite a few Carbonite instances already and I'd like to be able to be a bit flexible.

From what I have read online, Carbonite acts more like a traditional backup solution. Think of it like a cloud tape backup. The client software collects up all files of certain types from your "Users" directories and sends them to their storage facility. If you want something restored, you have to explicitly tell them to send the file back to you.

With this in mind, I don't think that you original requirement to delete or restore files with a batch script would be possible with Carbonite.

I wonder if it matters which version of Carbonite is being used?  It appears the products vary quite a bit in terms of such capabilities.

The questions remain for SugarSync and SpiderOak (the latter I'd never heard of before....).

I do NOT recommend the vanilla version of dropbox as a backup because it is not a true backup at all.  Spideroak is very good in terms of retention and ease of use with command line options.  I have used spideroak for years and up until several weeks ago would have recommended this as your best option.  I am currently using Crashplan as my backup option.  CrashPlanPROe is an excellent product for business (enterprise version).  We have run it locally (we have a local CP server instead of using their cloud) for a couple of years now.  I switched from spideroak to crashplan at home as well.  I am not as familiar with the command line in CP, but I do know that at work we can monitor and control virtually everything through a graphical interface, including getting various stats.

My article on why I changed from SpiderOak to CrashPlan is here:

I also wrote a basic article on backup here:

I tried sugarsync and didn't like it at all - I don't remember exactly why.  Versioning is key here.  backup without versioning is useless and a robust restore option is necessary.  I believe that CP has the best options.  Moreover, CP will allow users to do their own restores (read less of a headache for you).  Also CP allowed us to easily recover from a cryptowall infection (in less than 2 hours) due to the versioning.

RE: "Using a script"

So far, the list of possibilities that I've gotten here are:
DropBox

I've also learned that there is a developer's interface with SugarSync that appears to offer a way to automate scripts.

As I said above I really feel dropbox is not true backup. Scripting should be fairly easy with spideroak,  like I said I have experience work the command line in spideroak.  I imagine crashplan has a similar command line interface. Either way I have not seen the kind of versioning support that is needed in dropbox. Also note that the algorithm puts a copy of each file on the source computer, including versioning.

So far now I have found that scripting should be possible with:

DropBox
SpiderOak
SugarSync

But it's not clear if SpiderOak or SugarSync would be dealt with using Windows command prompt scripts /  .bat files??
