new kubuntu and old aptik files

[oldgeek]

Today I took the big jump and deleted the Windows and Neon/Kubuntu hybrid portions of the HD and installed Kubuntu 18.04 using the btrfs file system, of which I am all but illiterate but ready to learn. The actual download and installation went well, and my hand did not tremble when I eliminated everything on my hard disk in order to install Kubuntu 18.04 fresh and clean, eliminating Windows forever as collateral damage. After the installation had completed I installed Aptik and, contrary to the advice in this forum, decided to restore everything on the backup except certain repositories which I had eliminated (basically all Trusty Tar and Xenial sites). I was curious to see if Aptik worked, to be simple. And it did. I lost most of my games and astronomy programs, which are easy to restore, and successfully restored all my documents and a good deal of my previous programs without, so far, a single crash. It's nice to know that Aptik does its job, although with some restrictions. Why didn't my games get through? (Apart from my Steam games, and Greygeek's favorite, Universe Sandbox (fantastic program)) I was a little worried about using this method to get my computer rapidly up-to-date, and am satisfied with the results. Now, where can I find my btrfs partitions in Dolphin?

OK, found the pertinent btrfs folders, but it wasn't obvious. At least I know that I'm on the right track.

Your "btrfs partitions"? How did you install Bionic when you were at the partition formatting stage of the installation?

In a typical Btrfs where it becomes the root filesystem the entire partition (/dev/sda1, for example) is given to Btrfs. If that is the case then ALL of your file system is on Btrfs. As root you can mount your Btrfs drive to /mnt and under /mnt you will find @ and @home, the two Btrfs partitions created during the install.

I found the icons under /root/subvolumes. I only have one partition now--got rid of Windows, and set it up with btrfs. So I guess I'm ready to roll. I presume all the actions with btrfs are done on Konsole.

That's entirely up to you. I've used a couple GUI Btrfs snapshot & rollback apps but eventually settled on using the Konsole because it is so easy. But, Snapper works nice if you modify its config file so that no more than about 5 snapshots are kept at any given time. TimeShift works with Btrfs too, but you must be careful that you delete ALL snapshots before you delete the app, if you decide to delete it.

What is important is that for at certain important times, like right before a major upgrade, you create snapshots of @ and @home and then use btrfs send & receive to move them to a second, external Btrfs pool, or to a non Btrfs HD using the "-f" switch in the send command. That way, you can boot a LiveUSB that uses Btrfs, mount your external Btrfs pool, send & receive @ and @home snapshots to <ROOT_FS> and reboot.
