Subject: What's data/meta/_dokuwiki.changes.trimmed for?
Hi,

I've noticed that my differential backups detect daily changes in my Dokuwiki installation, without me changing any content (cache, index, locks and tmp are excluded from my backup).

I think I've narrowed it down to data/meta/_media.changes.trimmed and data/meta/_dokuwiki.changes.trimmed. Both files have a size of zero bytes, but are touched daily.

What's their function? Do I harm myself if I don't backup them?

It's obviously not a big problem, but if I could exclude those two files, it would be nice.

Take a look at: https://www.dokuwiki.org/devel:changelog

The changelog is stored in per-page changelog files, with a recent changes cache. The recent changes cache is kept in /data/meta/_dokuwiki.changes and trimmed daily.

Feedback welcome - Michael Sy.
By Patreon.com a few eurons can be fed into the code phasers of
the DokuWiki engine. Besides, Andi's posts are worth reading.

They record the time when the changelogs were last trimmed. You can skip them in your backup if you want.
