I've been doing this for more than ten years: massive backups with
rsync and --link-dest.

I started with reiserfs and it went on for more than ten years without
any problem.
Then I rebuilt the machines and decided to move to ext4.
Ironically enough, I got into a serious bug in ext4 online expansion
that caused data corruption. It is now solved, of course.
Today, I would go for ext4. I have just a couple of system still
on reiserfs, with very old (read: proven and trusted) software versions.
