Which file system for data harddisk

Hello,
Today I have Installed Ubuntu as system for our cloud.

Now I ask me, which file system (btrfs, ext4,…)for the data harddisk are the best.

Could you tell me please that?

Thank you in advanced!

Best regards
Christoph

Somewhat down to user preference, but EXT4 is tried & tested and is usually the go-to format on any Ubuntu system.

I started to work a bit with btrfs, it has really some nice features. This report is already two years old, so some details may have changed:

If you only fancy the snapshot function, you can also have a look at LVM.

hello,
thanks for information.

if i am true understand is btrfs the better system format.

Btrfs has some features that ext4 does not provide but it is less mature (less tested).

Thank you for your Help!

Best regards
