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
