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.

I thought (also most people said) keeping the Backup in same partition as root defeats the purpose of Backup and brings certain inconvenience like can't just delete the partition. Also I don't know if its possible to restore a backup from a partition to the same partition itself.
I'm aware that BTRFS has certain adavantages. But the whole BTRFS is alien to me, as I'm new to Linux. Also I assumed that BTRFS doesn't have enough community support as ext4 is default on Linux and many people just aren't bothered to change it.
I only use Windows for DaVinci Resolve Free. And for the possibility of requiring Windows exclusive programs in the future as I'm an Engineering Student.
Thank You.
Btrfs is well supported.
Btrfs uses snapshots and subvolumes. It is not a traditional partition and can restore to itself.
I think Timeshift is primarily a snapshotting tool for a quick rollback if something breaks. I would not consider it a full backup tool, there are tools that are much more robust and configurable for keeping files safe and elsewhere.
But AFAIK, Only Pika Backup has intuitive GUI. And It's auto backup doen't work on Mint 21.3 cause of some old packge. So I sticked to TimeShift.
Vorta, Deja Dup (duplicity), duplicati are some others.
All of utilities you suggested are awesome.
Which one do you suggest? And why?
I would recommend using Timeshift. BTRFS mode can create local snapshots and rsync mode can be used to backup to external media. Timeshift can exclude directories based on user preferences.
So BTRFS can't create external backups?
Btrfs can send a snapshot to another machine, but there is no pretty gui for it.
Most file systems cannot do this.
How about just another partition on the same disk though?
As the other user says, btrfs is well supported. In fact it is preferable in your case, as it allows you to use transparent compression for the whole system. In addition, btrfs snapshots are also drastically safer and faster.
So, I have to Install my whole system again? I just started before a month though.
You can convert it from ext4 to btrfs, but I don't know how well it works. If you are going to do it, I suggest you check it carefully and make a backup.
Thanks.
Thank You for detailed information.
I think I should learn more about BTRFS and practice installing or converting it in VM.
I'll look into it. I'm using Mint Cinnamon right now.
Thanks.
