Fieldbox Backup copies your memory card to an archive on your iPhone or iPad, compares source and copied SHA-256 values, then uploads copies to your own cloud accounts. It records which files matched their source at transfer time and which providers confirmed a complete upload. Before a transfer starts, every scanned file has an explicit outcome: selected, already verified in the session, or deliberately excluded. You can adjust the current transfer directly by file type. Every copied file is checked with SHA-256. Fieldbox records a verified local file only when its source and copied values match. Cloud status separately shows when a provider has accepted an upload and confirmed its stored size. S3-compatible storage and Google Drive also require a matching provider-reported SHA-256 hash; Dropbox, OneDrive, and WebDAV report upload/size confirmation where a provider checksum is unavailable. Backup Status shows the current 3-2-1 inventory: three copies, two kinds of storage, and one offsite. Normally that is your original card, a verified copy on your device, and a complete confirmed cloud copy. If you mark a source card formatted, two independently confirmed cloud providers can supply the non-device copies. Connect the cloud you already use: Backblaze B2 and other S3-compatible storage, Dropbox, Google Drive, OneDrive, or WebDAV/NAS. You can see which provider holds a complete copy, with clear status for every transfer. With Fieldbox Pro, files missing from your device can be repaired from the original card or a confirmed cloud copy. Fieldbox downloads to staging and returns a file to the archive only after its SHA-256 matches the recorded source hash. The session activity history records source-card status, cloud-provider changes, confirmed copies, deletions, repairs, and USB Transfers. If a transfer is interrupted, Fieldbox keeps the verified-file checkpoints and resumes only after the reconnected source matches the recorded card identity, selected folder, inventory, and checkpoint evidence. A read-only source recheck can refresh the recorded card coverage later without starting another transfer. Create and export a signed Integrity Record for a point-in-time summary of the session and its recorded evidence. The self-issued device signature provides tamper evidence and signing-key continuity. It is not external certification, trusted time, or proof that a copy still exists. Built for the field: • Works offline. Back up now, sync to the cloud when you have a connection. • Browse and preview your photos, including RAW and HEIC. • Recognizes common camera RAW formats, still images, video, audio, and XMP, XML, or JSON sidecars. This includes 3FR, CR2, CR3, NEF, ARW, RAF, DNG, BRAW, R3D, and other listed formats. • Organize by session and camera, with EXIF and copyright details. • The one-time unlock supports up to three user-selected active sessions that may keep receiving files. Every preserved session remains readable and verifiable, and you can change the active selection later. • Fieldbox Pro adds unlimited local sessions, planning, share and Photos export of working copies, selective local-file removal, verified repair, detailed events, Camera Profiles and Memory Cards management, additional themes, multiple cloud destinations with concurrent uploads, and USB Transfer to external drives. Every non-revoked Pro purchase also includes permanent ownership of the standard Unlock. • Share one cloud account across devices. Fieldbox gives each device a separate top-level area and limits cloud deletion to the current device's area. Review Backup Status and your normal workflow before deciding to reuse a card. Fieldbox never formats, erases, or changes the original source media.
