Comment(by warner):

 Take a look at source:docs/backupdb.txt . Clients of the backupdb (like
 "tahoe backup") are required to eventually do a filecheck on the files
 that they skip uploading. It uses an age-since-last-check -based
 probability. The timer values are set such that all files will be checked
 at least every two months. If the check indicates unhealthy, the file is

 It would probably be useful to make these timers configurable. Setting
 them to "zero" would give you the check-each-time behavior you'd like.
 source:src/allmydata/scripts/backupdb.py#L163 ({{{NO_CHECK_BEFORE}}} and
 {{{ALWAYS_CHECK_AFTER}}} in {{{BackupDB_v2}}}) are the values that would
 need configuring.
