I'm still working on a solution for the problems I raised in the
thread "A survey of GUI-based free online backup."<br>
<br>
I have swung this way and that looking for the best approach. Time
and again, I have found something that is promising in one regard
but undesirable in another.<br>
<br>
Here is where I am right now. <br>
<br>
Copy.com offers 15GB of free storage with a Linux client, but the
client is really just a sync program, and you have to place all your
files in a designated folder. If you want to preserve your default
user profile folders, you could backup all your user files to the
designated sync folder.<br>
<br>
Box.com offers 10GB of free storage. They don't have a Linux
client, but they do support WebDAV. So you then need either a
backup program that supports WebDAV, or you can use davfs2 to map a
local drive to the WebDAV resource, and back up to the mapped
drive. In either case you need a backup program.<br>
<br>
So with either Copy.com or Box.com, the backup program is a critical
ingredient.<br>
<br>

Notes on a couple of promising backup programs:<br>
<br>
Duplicity (say, with front end Deja Dup) has lots of strengths, but
a full backup should be run periodically, and you really don't want
to do that because of the difficulty of a multi-GB upload. <br>
<br>
Duplicity -- why a periodic full backup? See <a
href="http://www.linux-magazine.com/Online/Features/Cloud-Backup-with-Duplicity">http://www.linux-magazine.com/Online/Features/Cloud-Backup-with-Duplicity</a>,
where it says:<br>
<blockquote><i>Thus, in principle, you could just create one full
backup and then use incremental backups for the changes. The
developers of Duplicity warn customers, however: Not only can a
mistake in one incremental part ruin the entire backup, but
restoring files takes quite a long time if the software needs to
run through all the incremental backups</i>.<br>
</blockquote>
Duplicati 2 (based on Duplicity) overcomes that problem with an
approach that reliably merges 256KB diffs into an existing full
backup. The 256KB chunk size keeps uploads reasonable. It supports
Google Drive, MS Onedrive, and other destinations. But the Linux
version requires installing Mono, which can run the Duplicati C#
code that also runs on .NET Framework under Windows. This is
convenient for a small project to extend its platform reach, but it
seems to me that it introduces security risks, since .NET Framework
malware does exist.<br>
<br>
This may be an impossible spec, but I'd like to find a backup
program that:<br>
- will run in Lubuntu without installing a load of dependencies for
another environment<br>
- has a GUI (perhaps largely for the sake of Restores by average
users)<br>
- doesn't require a periodic full backup<br>
- supports good encryption<br>
- supports compression<br>
- supports breaking the backup into nicely uploadable small chunks<br>
- is not buggy<br>
- preferably does auto-deletion of older backups, or supports
versioning, or will send an email when a backup fails<br>
<br>
If that is an impossible spec in the current state of affairs, I'd
like opinions on the best compromises. <br>
<br>
(I've been using SpiderOak, which has a nice Linux client and 2GB of
free storage, but that's not much storage these days, and I'd like
to hit on a better free solution that I can set up on systems that I
put together for people.)<br>
