Should I increase inode count for a rsync backup volume?

Considering rsync used for incremental OS backup creates hardlink farms for all non-differing files, if I use it to backup a large, slowly-changing system regularly to a dedicated volume, I'm worried I'll run out of inodes for the hardlinks ages before I run out of diskspace.

Would it be better to tinker with mke2fs parameters and increase number(density) of inodes for such a disk, or is the default sufficient for backing up typical 'desktop Linux' with a good multimedia library... or maybe a different FS than ext3 would be better?
