What ADVANCED DOWNLOADING LIMITED does

Advanced Downloading Limited is a London-based, privately held data conversion and backup media recovery service bureau founded in 1992 (with roots in the 1984 A L Downloading Services business, whose conversion activities it acquired in 2005). The company specializes in magnetic tape, cartridge, LTO, and DLT data conversion, recovery, migration, duplication, transcription, and cataloging, serving enterprise customers in the UK, Europe, and the United States who need to extract, migrate, or recover data from legacy and obsolete backup media.

The firm's core technology consists of banks of magnetic tape drives and servers running 24/7, staffed by experts who reverse-engineer obscure data formats that other bureaus cannot crack, including VAX VMS backup savesets, AS/400 SAVLIB and SAVOBJ, corrupted .bkf files, variable-length packed decimal, and proprietary binary date structures. It supports more than 80 tape and disc formats and 15+ backup software formats (NTBACKUP, Backup Exec, Arcserve, Netbackup, TAR, CPIO, VMS Backup, Legato Networker, BRU, SAVLIB), covering everything from ½" 9-track reel to LTO-5 and magneto-optical discs.

The business operates on a professional services model: customers contact the firm for free tape evaluation and custom quotations, with services delivered from the London facility. Distribution is sales-led and direct, supplemented by an indirect channel in which other UK, European, and US conversion bureaus sub-contract their most difficult work to Advanced Downloading. Revenue is generated per project rather than through recurring contracts, and pricing is not publicly disclosed.

Broad incumbents

• Iron Mountain: Global information management and storage company offering tape migration, media vaulting, data restoration and digital transformation services. Overlaps with Advanced Downloading on enterprise tape and archive migration but at vastly greater scale and broader service portfolio.
• Eastman Kodak (Entertainment Imaging / Archive): Legacy media and archive services including film and tape digitisation and restoration at enterprise scale. Comparable archive restoration and digitisation capabilities but with much broader film and imaging focus.
• DriveSavers Data Recovery: Specialist data recovery firm handling tapes, hard drives and other storage media for enterprise and consumer customers. Directly comparable tape and cartridge recovery proposition, though broader across non-tape media.

• Gillware Data Recovery: US-based data recovery services company with tape and disk recovery capabilities and proprietary tooling. Comparable tape recovery services, with a more digitised acquisition funnel and broader geographic reach.

Regional players
