From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hi all, Just wanted to know, do these all work the same? I have ext4, so no snapshots on timeshift, but I'm using it now to back up to an external SD card. I have heard good things about Pika and dejadup, and had some mishaps with timeshift. So, my question is, do they all do the same thing? Like, if I messed up something, can I use any of these apps to restore to a previous point where the system was working? And what the best backup app in your opinion?

Edit: Basically, I'm looking for a backup app that I can use to do both, backup my whole system and restore to a working state if I borked something. Just like timeshift, but timeshift scares me, because I've had some issues with it where the whole system just got messed up, and I had to reinstall (all ext4 btw) Thanks in advance

Just go BTRFS and get it over with. Snapshots are a game changer and I'm never going back.

Can't do btrfs on this laptop. Nvme is a bitch. I had an issue where the laptop wakes up to a black screen every time I open the lid.

Oh, is that what it is? I had no end of problems with my laptop display not waking from sleep and failing to boot when I was using btrfs, but I assumed it being caused by something else.

Is that an NVME specific problem?

[–] donut4ever@lemm.ee 2 points 1 year ago

I believe so. I have read so much shit and yes nvme and btrfs don't like each other. Some people say because of timeshift, some say because of swap file. I just removed btrfs and used ext4 and end it all. Now no issues
