Working with snapshots is a standard development practice, however, depending on the number of snapshots that are saved, this can use up large quantities of disk space.
To specify the maximum number of snapshots that may be stored, in the Administration module, select the Repositories and click the repository whose settings you want to edit.
In the Basic settings, check Handle Snapshots and then set the Max Unique Snapshots field. This value is zero by default, which means that all snapshots are saved.
