I'm using Endeavor OS. My computer lost power during system update. Now I can boot into it.

Never listen to BTRFS shills. EXT4/XFS or bust.
LUKS > LVM > ext4
Every time I install a new OS I ask myself if I should use BTRFS, if for no other reason than just to experience it. But I've never found a good enough reason that's worth even a sliver of stability loss over more mature options.
It's probably because I've also been burned too many times trying ReFS over NTFS on Windows (except for Veeam).
Scenarios as this one are why you need backups. Always.
And yes, Ext4 is a log file system which is much more stable in the scenario of a power outage, but it won't protect you e.g. from faulty RAM and corruption of kernel data structures.
On top of that, it can also be a adequate solution to use BTRFS (plus backups) for a system install of a few GB, and EXT4 (PLUS BACKUPS) for user data.
Also, because sibling comment mentions LVM, it is great, and solid, but it has its own complexity which introduces extra chances for user error. And user error is a main cause for data loss, so it is no silver bullet either.
How do i backup my filesystem? It is a 2tb drive... where do i backup my filesystem to?
Are we saying that BTRFS corruption is not recoverable? 😦
Usually with several larger external drives, e.g. 8 TB.
You need to check the docs for the version you are using. Generally, in that area it is much weaker than ext4.
