* If the versions app is enabled (default), this setting defines the policy
|

* for when versions will be permanently deleted.
|
||||
* The app allows for two settings, a minimum time for version retention,
|
||||
* and a maximum time for version retention.
|
||||
* Minimum time is the number of days a version will be kept, after which it
|
||||
* may be deleted. Maximum time is the number of days at which it is guaranteed
|
||||
* to be deleted.
|
||||
* Both minimum and maximum times can be set together to explicitly define
|
||||
* version deletion. For migration purposes, this setting is installed
|
||||
* initially set to "auto", which is equivalent to the default setting in
|
||||
* ownCloud 8.1 and before.
|
||||
*
|
||||
* Available values:
|
||||
* ``auto`` default setting. Automatically expire versions according to
|
||||
* expire rules. Please refer to Files_versions online documentation
|
||||
* for more info.
|
||||
* ``D, auto`` keep versions at least for D days, apply expire rules to all
|
||||
* versions that older than D days
|
||||
* * ``auto, D`` delete all versions that are older than D days automatically,
|
||||
* delete other versions according to expire rules
|
||||
* * ``D1, D2`` keep versions for at least D1 days and delete when exceeds D2 days
|
