command, the first argument after the volume name in the exam-
ple indicates how many weekly snapshots to keep (2), the second argument indicates
how many nightly snapshots to keep (6), and the third argument indicates how many

for that interval.

the hours at which the filer creates the snapshots in 24-hour time (8, 12, 17, 20). If the
