In a short answer, yes!
Incremental Backup is a completely secure process, and will not cause any additional data loss for your device, as per any other kind of backup. It is a quick and easy way to back up your data, saving storage.
During a scan, Enigma Recovery software will scan your device and create a separate backup file with the data on your device. This file is stored on your computer only, and can be deleted by you at any time.
