A GIS field backup drive should be portable, compatible with the survey laptop and large enough for project files, imagery, exports and several working versions. Field reliability comes from multiple copies and a tested transfer routine, not from spending the entire equipment allowance on one device.
Separate the travel copy from the archive
The Hiksemi Pocket 1TB portable SSD costs R900, while the LaCie Rugged 2TB USB-C drive costs R1,920 in the verified facts. Confirm current stock, exact drive type, connection, laptop compatibility, included cable, physical protection and warranty. Capacity should be checked against the real project folder rather than estimated from document files alone.
Copy a representative dataset, open it from the destination and verify coordinate files, linked layers and metadata. Use clear project, date and location names so field versions cannot be confused. Keep active work on suitable fast storage, make a second copy before leaving the site and retain another protected copy away from the travel bag.
Protect the drive from water, dust, impact and unattended vehicles. Encrypt sensitive survey or client data where policy requires it, and store recovery details securely. Perform a restore test before the trip, then repeat it after the first collection day. The right drive supports the workflow, while the separate archive protects against loss of both the laptop and field copy.
