I'm trying to find a backup software for Ubuntu that will create backups in chunks for specified limit.

Think of it like splitting a RAR into multiple 50mb files.

I've tried Back In Time and Simple Backup but both are not offering that feature.

Can you recommend a program that does?

If there's no such program, perhaps even snapshot-catching backup script that does the same would also work.

you can create a tarball and then split it. see man tar and man split for more information. I recommend xz compression.

also there are rsnap? is capable of creating incremental backups with rsync, although for incremental I'd ask myself if a version control system might work.

This is what I'd do,

tar cfj target.tar.bz2 [files]
split -b=BYTESIZE target.tar.bz2 splitpack.
# Note: the '.' at the end is part of my command

The files can be rejoined with,

cat splitpack.* > target-repack.tar.bz2
#   =========^= this is how the '.' works

Try this out and check with 

diff target.tar.bz2 target-repack.tar.bz2

Do read the short manual page for split for its simple options.
