"Backups", by default in Trisquel, is easy-to-use and, most importantly,  

incremental backup (only backup files that are new or were modified);
compressed backup (faster and save space);
integrated with the file manager (you revert to any previous version of the  
file/folder in about three clicks);
periodic backup (or a notification if the external drive is not plugged);
the oldest versions of the files are automatically removed if space is  
very easy to use (choose where to backup and then use the graphical utility  
with two buttons: "backup" and "restore");
possible encryption;

It can backup remotely.  For example to an SSH folder (or to an FTP server or  
...).  That is what I would do:

Configure your router so that the Ethernet card of the Hyperbola desktop  
always receives the same IP address; permanently binding the hardware id of  
the card, six two-digit hexadecimal numbers separated by ":" right after  
"link/ether" in the output of 'ip addr', to the chosen IP address  
(192.168.x.x for a private IPv4 address);
Install an SSH server (OpenSSH is the most popular) on the Hyperbola desktop;
Make it be launched at init (on Trisquel, that would be automatically done,  
after installing; I do not know if that is the case with Hyperbola);
Launch "Backups" on the Trisquel laptop, in MATE's "Control Center";
Choose "SSH" as the "Storage location", write down the IP address chosen  
earlier as the "Server"; specify the folder where to backup and the login of  
the user on the Hyperbola desktop (with the permissions to write in that  
folder); "Port" can stay as it is, unless you changed the default (22),  
configuring the SSH server;
Configure the rest of the backup, as you wish (e.g., specifying weekly or  
daily automatic backups).

The hardest part is the first one, where precise instructions depend on your  
router.  Once everything done, ask for the first backup, clicking on the  
"Back Up Now" button, in the "Overview" tab of "Backups".  The password of  
the specified user on the Hyperbola desktop will be asked and everything  
should be fine.
