- <description>Versioning of files</description>
+ <description>
+ ownCloud supports simple version control for files. The versioning app
+ expires old versions automatically to make sure that
+ the user doesn't run out of space. Following pattern is used to delete
+ old versions:
+ For the first 10 seconds ownCloud keeps one version every 2 seconds;
+ For the first hour ownCloud keeps one version every minute;
+ For the first 24 hours ownCloud keeps one version every hour;
+ For the first 30 days ownCloud keeps one version every day;
+ After the first 30 days ownCloud keeps one version every week.
+
+ The versions are adjusted along this pattern every time a new version gets
+ created.
+
+ Beside that the version app takes care to never use more that 50% of the users
+ currently available free space. If the stored versions exceed this limit
+ ownCloud deletes the oldest versions until it meets the memory usage limit
+ again.
