Amazon S3
Signed off-site uploads with SigV4 and multipart resume at part level for large packages.
3-2-1 backup
Back up off-site without exposing what must stay controlled.
Obscura Flow remains local-first: off-site backup and sync are guided, optional, and never expose originals without your agreement.
Control
Off-site, without ever losing control.
Copy your archives to the cloud or a local volume, resume interrupted transfers, and keep a clear view of the copies you expect — following the strategy you choose.
Destinations
Local, off-site, or hybrid — your call.
From S3-compatible targets to local volumes, every copy stays readable and resumes if interrupted.
Backblaze B2
S3-compatible destination for cost-conscious dormant copies in a 3-2-1 strategy.
Cloudflare R2
S3-compatible destination without egress fees, suited to backup and controlled distribution.
NAS / local folder
Off-site copy without depending on a third-party cloud, to a network volume or dedicated drive.
Resumable uploads
Interrupted uploads restart from where they stopped, without resending everything.
Optional sync
Catalogs, thumbnails, and proxies sync through signed links when you choose, never by default.
Decision
Build an archive that stays understandable.
