CopyProof: USB Photo Backup

New: back up your photo library to your own Storj cloud — straight from your iPhone, every file verified with SHA-256. USB drives, SSDs and SD cards work as before.

CopyProof copies photos and videos from your iPhone, iPad or Mac library to an external drive, a folder you choose or your own Storj cloud bucket — in parallel and verified file by file. It only copies: nothing is ever deleted from your library.

MULTI-THREADED COPYING Most apps copy one file at a time. CopyProof runs up to 20 parallel streams, so a large library moves in a fraction of the time. You choose the number of streams yourself.

EVERY FILE IS VERIFIED Each copied file is checked with a SHA-256 checksum, so the copy is byte-for-byte identical to the original. Files that fail the check are listed and can be copied again with one tap.

STRAIGHT TO YOUR STORJ CLOUD Connect your own Storj bucket and copy photos straight from your device to the decentralized cloud. There is no server of ours in between: the keys stay in this device's keychain, and every file is checked with SHA-256 on the Storj side.

RESUMES WHERE IT STOPPED Drive unplugged, app closed, battery died — copying picks up exactly where it stopped, without re-transferring what is already done.

COPY ONLY WHAT YOU NEED Copy the whole library or pick by album, year, month, media type or favorites, and exclude single files by hand. Split a large library into batches by year or by album.

TWO DESTINATIONS, NO INTERRUPTIONS Add a second drive or folder as overflow. When the first one runs out of free space, copying continues to the second one automatically — no need to watch it or split the library by hand.

AN ORGANIZED ARCHIVE Folders by year / month / day; newest or oldest first.

A REPORT AT THE END See how many files were copied and verified, how much space they take, and which files need attention. Share the result card to earn bonus tokens: 200 for the first report, fewer for each next one.

TOKENS One token per copied file. New users start with 1,000 tokens, extra copy streams are unlocked with tokens, and packs can be purchased at any time. Prefer no limits? The Unlimited subscription, monthly or yearly, lets you copy and clean without spending tokens while it is active.

PRIVACY Photos and videos go straight to your drive or to your own Storj bucket. Nothing passes through our servers.
