Its limitation is that it doesn't handle large
(4GB or larger) backups.
* dump is designed specifically for tapes; its main strengths are its
interface for file restores, low-level filesystem backups, and
incremental backup scheduling. Its limitations include the inability
to back up NFS or other non-ext2 filesystems and some rather arcane
defaults.
* GNU tar (short for Tape ARchiver) is an implementation of what is
probably the most widely used backup or archiving utility in Linux
today. It makes a good general purpose tool and can deal with the
widest variety of target media. Additionally, many different systems
can read tar files, making them highly portable. tar's weaknesses
include a weaker incremental backup system than dump and no
interactive restore selection screen.

Because tar is used so much, and for quite a bit in addition to backups,
it is being described here. For more details, see the tar manual page;
instructions for viewing manual pages can be found in section 5.1 on page
[*].
tar is an archiver.
