TurtleBackup vs zDrivePro

Easily backup files from memory cards to external drive (like USB flash drive) or to internal storage. Combined with a compatible USB hub / card reader, it’s a simple and lightweight photo backup solution for travel / short trips.  Has 4 main features: Check, Backup, Integrity check, History.  "Check" gives a brief overview / size estimate, and also confirms whether basic conditions (e.g. available space) are met.  "Backup" copies files from source to destination. You have 3 options regarding folder structure on destination: • use original (same as source) folder structure • group files into folders by file creation date (YYYY-MM-DD, example: 2026-02-10/DSC_5555.JPG) or • group files by file creation date and type (YYYY-MM-DD/type, example: 2026-02-10/JPG/DSC_5555.JPG) There's also a filter feature - you can exclude files created before certain date (e.g. if you want to skip files created before the trip, but don't want to delete them from source). Incremental backup is supported as well - matching existing files are skipped, if size (and file creation time, depending on selected setting) is the same. Also, if you're using same backup source / destination each time, app will remember and pre-select them on startup, so in ideal scenario, backup can be performed just by clicking couple of buttons. "Integrity check" is optional, compares checksums of corresponding files from source folder to the ones in the destination folder. "History" is optional (can be enabled via settings) - saves (locally) basic statistics (date, number of files, etc.) about performed backups, which you can review later. App doesn't need a network connection and does not support backup to network locations (cloud etc.).

zDrivePro is designed to let you use your iPhone like a portable hard drive in your pocket: files reside in the app's own space; from here they are listed, previewed, and managed. WHAT IT DOES? • Drag and drop files from your Mac to the zDrivePro space in Finder → Device → Files tab when connected via USB or Wi-Fi. • Import photos and videos from the gallery with "Add from Gallery"; import suitable files back to your gallery with "Save to Photos". • Full-screen gallery for photos and videos; quick preview for other files. • Share and delete files; list or grid view, sort by name/type/date/size. • Lock with optional Face ID / Touch ID or app passcode — authenticate when unlocking after exiting the app. STORAGE SUMMARY See in-app usage, free space on the device, total number of files, and distribution by type all in one screen. IMPORTANT Deleting zDrivePro from your iPhone will permanently delete all files within the app. Regularly copy important data to your Mac or a trusted backup.
