Years of photos on old drives, full camera cards, a cloud bill that never stops. Holm brings it all onto drives you own — organised the same way every time, with a verified backup before anything is ever touched.
2+
copies written at once — primary and backup, every time.
SHA-256
checksum on every file, confirmed at the destination.
0
originals deleted before a verified copy exists.
A look inside
Back up to every drive at once
Holm recognises the camera, shows only what's new, and writes a copy to every drive you've chosen — in one pass.
Every copy verified, byte for byte
Holm doesn't just copy — it re-reads every file with a SHA-256 checksum, so you know each backup is whole.
