Limit number of backups for windows components

I am using “backup windows components” feature for my SQL server databases.
There is one problem though, these backups are using most of my disk storage as they never get deleted (I still have backups from when I installed urbackup). I don’t necessarily need such a long history and maybe 5-6 snapshots would be more than enough.
Is there an option to limit number of these backups? Also is it safe to just delete entries from disk?

Hi

You could try setting it up as a virtual client with only windows component enabled
