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
 re-uploaded.

 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.
