Da quanto ho letto verso le 5:30 del mattino
sulla guida al punto 3.2 che riporto qui di seguito, mi pareva di aver capito che è possibile solo con la versione Professional (commerciale)
3.2. Off-site Directories Inclusion
This feature is available only in Akeeba Backup Professional, the paid version of our component
More often than not, seasoned web masters prefer to place file repositories outside the site's root (usually, outside the
web server's root as well!) in order to deter potential crackers and "leechers" from having direct access to those files.
Such repositories can include downloads, image galleries, media (audio and video) or controlled access documents
files. As you know, Akeeba Backup Core will only backup file under the site's root, which made these files impossible
to backup. Well, it's possible with Akeeba Backup Professional.
Using the off-site directories inclusion, Akeeba Backup can be instructed to look for files in arbitrary locations, even
if they are outside the site's root (hence the name). All the directories included with this filter will be placed in the
archive as subdirectories of another folder, in order to avoid directory name clashes. We call this folder the "virtual
folder", because it doesn't physically exist on the server, it only exists inside the backup archive.
For example, if you want to backup an off-site directory named images , if we weren't using the virtual folder it's
contents would end up being backed up (and subsequently restored!) inside the Joomla! images directory. This is
something you'd like to happen. If your virtual folder is called my_offsite_includes , this directory would end
up being backed up as something like my_offsite_includes\1-images . Notice the number and the dash
before the actual directory name? This is a smart feature which allows you to backup many directories of the same
name. You could, for instance, backup two directories named images , confident that there would be no name clash
inside the archive.
Since keeping track of these folders is a pain, Akeeba Backup includes a readme.txt text file inside the virtual
folder which tells you which backed up folder corresponds to which physical folder, making it easy for you to restore
these directories to their rightful place.
