Introduction

Digital preservation and curation ensure that diverse electronic resources remain accessible, authentic, and understandable over time. As reliance on digital storage grows, protecting these assets becomes critical. However, constant threats compromise long-term data integrity, making an understanding of these challenges fundamental to developing sustainable curation strategies (Corrado & Sandy, 2017).

Rapid technological obsolescence and physical media deterioration severely threaten digital materials. Evolving systems render formats like floppy disks or old word-processor files unreadable, while environmental factors degrade physical storage lifespans, causing bit rot or mechanical failure on CDs, hard drives, and magnetic tapes. Organizations must combat these vulnerabilities through continuous migration, emulation, and robust storage management to prevent data corruption (Harvey, 2011; Ross, 2012).

According to UNESCO, (2021) states that cybersecurity threats is also a threat, this includes hacking, malware, and ransomware risk permanently destroying or altering digital records. Consequently, effective preservation strategies must integrate robust encryption, access controls, backups, and audits

Another challenge is the lack of adequate metadata and documentation. Metadata provides contextual information about digital objects, including their creation, ownership, format, and preservation history. Without sufficient metadata, digital materials may become difficult to locate, interpret, authenticate, or manage over time. Furthermore, inadequate documentation can significantly reduce the usability and value of preserved information, particularly in research and archival contexts where understanding the provenance and context of records is crucial (Higgins, 2018).

According to Lavoie, (2014) states that financial constraints severely threaten long-term digital curation, especially within developing nations, leading directly to inadequate planning and increased information loss Concurrently, the massive explosion of big data and diverse file formats like multimedia or datasets complicates large-scale preservation. To manage this vast, complex daily influx effectively, modern organizations urgently require sophisticated technologies, clear selection policies, and robust infrastructure frameworks (Sayao & Sales, 2015).

Another point is legal restrictions like copyright and privacy hinder digital preservation efforts. Institutions struggle to balance long-term preservation needs with legal compliance (Corrado & Sandy, 2017). Responsible stewardship requires proactive policies that address both preservation requirements and legal obligations to ensure compliance.

Conclusion

Digital preservation safeguards valuable resources for future generations against obsolescence, degradation, and security risks. Despite facing financial, metadata, and volume challenges, organizations must deploy comprehensive policies, sustainable funding, and robust infrastructure. This proactive mitigation ultimately ensures long-term asset authenticity and usability.
