Title:
  man-db's manipulation of index.db mtime timestamp interferes with
  incremental backups

Status in man-db package in Ubuntu:
  In Progress
Status in man-db package in Debian:
  Fix Released

Bug description:
  It appears that since version 2.7.0, man-db manipulates the mtime
  timestamp of /var/cache/man/de/index.db in a way that the content may
  change, while the timestamp is reset to its previous value (see
  attachment).

  See https://lists.ubuntu.com/archives/foundations-
  bugs/2014-September/209326.html

  This interferes with incremental backups which pick up files via their
  modification timestamps. Such backups will miss updated files which do
  not have their mtime timestamps changed accordingly. Automated
  comparisons between such backups and (btrfs snapshots of) their source
  data will fail. The integrity of such backups cannot be guaranteed.

  Release: Ubuntu 14.10
  Package: man-db 2.7.0.2-2
