Use ext4, that is has practically superseded ext3.
This article highlights the differences:
https://opensource.com/article/17/5/introduction-ext4-filesystem

Also in the Linux kernel user’s and administrator’s guide:
https://www.kernel.org/doc/html/latest/admin-guide/ext4.html
If you care fore the details or suffer of insomnia:
https://www.kernel.org/doc/html/latest/filesystems/ext4/index.html

As an aside, please let me know if two last articles are fully
accessible. I am interested in the answer because I consider using the
same software in the future to provide the Slint documentation. 

To just infrequently store data in batch mode on USB stick and read it
on occasion, you really do not anything more fancy like btrfs.

To answer Gregory whom I received the post while writing:

In this specific use case this is not an issue because the journal
will be written very infrequently.

This being said, you could go for ext2 instead, if you don't fear the
recovery time needed in case the computer stops during a backup for any
reason. But really, I think you can go for ext4.
