Your storage. Your rules.
Back up to any S3-compatible bucket, NAS, or local drive. macup is $5/mo per device. Storage you pay for directly, on the terms you already chose.
No card required
Twelve providers. Same engine.
Any S3-compatible provider, plus local NAS and direct-attached drives. macup treats Object-Lock-capable providers as a first-tier destination and flags the rest honestly.
One screen. One bucket. Done.
Add a destination in macup by pointing at your bucket or mount. No config files to edit. No YAML to write. We verify connectivity and Object Lock support at save time.
What this actually costs.
BYOS is $5/mo per device. Your storage vendor bills you separately. Here's what the total looks like for common shapes.
Wasabi: No egress fees.
Three flavours of BYOS, one of them ransomware-resistant.
Not every S3 provider offers Object Lock, and not every local destination is immutable. macup is honest about the distinction — your dashboard tells you exactly what protection each destination gives you.

About bringing your own storage.
What's 'Object Lock' and why does it matter?
Object Lock is an S3 feature that freezes objects for a retention period nobody can override — not you, not the storage provider, not ransomware. If your bucket supports it, macup enables compliance-mode Object Lock automatically and we call out that you have strong ransomware protection. If your bucket doesn't, backup still works but you lose that specific layer of defence.
Can I switch providers later?
Yes. macup can export your repository to a different provider in one step. Historical snapshots remain readable. You can even run two providers in parallel during a migration.
What if I run my own MinIO on a NAS?
Perfect fit. Enable Object Lock when you create the MinIO bucket and you have ransomware-resistant local storage. We'll treat it identically to a public cloud provider with Object Lock.
What about NAS over SMB or AFP?
Supported as a destination. No Object Lock available, so we flag it as append-only (macup's credentials have no delete permission locally, but an admin or attacker with NAS access could wipe the share). Good for fast local recovery; not a substitute for off-site, immutable storage.
What if my bucket runs out of space?
macup detects it at upload time, pauses the backup set, and emails you. Snapshots already uploaded stay intact. Free some space or raise the quota and macup resumes.
Can I see exactly what macup writes to my bucket?
Yes. macup uses a documented repository format — one top-level directory per workspace with a predictable layout. You can inspect, copy, or archive the contents using any S3-compatible tool.
