Public bug reported: 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.
