+# in the pool, ie: files that only have one link. To avoid race
+# conditions, BackupPC_nightly runs only when there are no backups
+# running, and no backups will start while it runs.

+# traverse 1/2, 1/4, 1/8 or 1/16th of the pool each night, meaning it
+# takes 2, 4, 8 or 16 days to completely traverse the pool. The
+# advantage is that each night the running time of BackupPC_nightly
+# is reduced roughly in proportion, since the total job is split
+# over multiple days. The disadvantage is that unused pool files
+# take longer to get deleted, which will slightly increase disk
+# usage.
