For the most part, in my specific cases, home and work, a snapshot (eg
rsnapshot) was the best because it was easy to restore individual files
and whole directory trees. But, it should always meet the needs of the
users and in some cases legal requirements. For a large organization,
incremental backups become necessary just because of the time issues and
the size of the data.
