+backup belongs to an epoch, which is 'sporadic' or one
+of the user-defined epochs. Standard epochs are year,
+month, week, day, or hour. The backup can be made
either full, differential or incremental.
\fBshbackup\fR takes care for pruning old
-backups. The user defines for each epoch the number of
+backups. The user defines for every epoch the number of
backups to keep, except for 'sporadic'. Sporadic
backups need to be removed manually.
