A backup is an additional copy of a music library stored separately from the primary collection.
Reliable backups protect DJs from data loss caused by hardware failure, theft, or accidental deletion.
External Storage
External storage devices such as SSDs and hard drives allow DJs to transport and back up large music libraries. External storage benefits from availability, but can be easily lost / damaged if mishandled.
Cloud Storage
Cloud storage provides an online backup for music libraries and important files. While not always suitable for live performance, due to the need for a stable WiFi connection, it offers an additional layer of protection against data loss.
