Rather than the image backup, the question here is the simpler backup, the data and config files and documents and stuff like that. A backup that you independently design and it may be a small quantity of data. (If you have huge volume, like with email or video or iso, it may get its own special time and method attention.)
There are two main backup places:
a) local drive - Mybook, USB, local server etc.
b) cloud drive - (gazillion spots)
For the local drives, you have inexpensive hardware and solid software easily available, such as:
Backup Maker - Ascomp
FBackup (free) or Backup4All (paid)
Best Free File-Based Backup Program - Aug 2014
[Windows] Best free file backup, drive backup (aka imaging), and system backup software - Feb, 2013
And many others. This allows flexibility (Preference, I would like one allows flexibility in the drive assignment of the target drive, to be overridden at the time of backup.) Since the quantity of data here is often small you have lots of flexibility in timing, target folder, multiple sets, etc. In many cases, you can even bypass incremental and simply do full backups of this volatile data.
What about the cloud? In earlier days we talked a lot about drive mapping, WebDav and tools like ExpanDrive and similar tools. Now I want to ferget about all those. Services don't see mapped drives anyway, some of the drive mapping tools are quirky, some are $$ for multiple puters, etc. Today, with the cloud sophistication, those could be more pain than gain for the home user.
Let's just find the best tool for user-defined backup to the cloud that has:
a) Good file-by-file backup software design (like Cobian, Backup4All, etc) with include/omits, specified files, folders, scheduling (can be triggered externally) etc.
b) Total Commander style file manager for looking at the target location and the home base.
DriveHQ definitely has (b).
Question: what web backup has the strongest combination of (a) and (b)? A is more critical, since it actually gets the data there.
Does not have to be free. Especially since this is being used for smaller volumes of data.
Does not have to synch in any way, but it can be a synch tool used in backup mode.
In the basic iteration of this question, you are including all Windows Desktop programs. e.g. DriveHQ's excellent file manager is
a Windows download and install.
In another iteration of this question, you wonder if there are any cloud-based tools that can do even a decent job.
The main purpose of mapping would be allow the desktop tools to be used to the external cloud. The question here is,
what is the next best way, without the mapping complexities and costs and another set of problems.
