Perhaps a simple but unorthodox way would be, if there is a list (e.g. property-file) of created log files is maintained and
persisted by logback. On every rollover the list is loaded and checked for old, deleteable files.
I assume, the list would not be that big, so that there should be no big performance impact.
One additional sugar piece would be, that if the filename patten (e.g. directory structure) is changed between a run of
the application, logback will still be able, to delete an old logfile, which does not follow the new (changed) file name pattern.
On the other hand, concurent access to this file via threads or several VMs will have to be synchronized?
