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: Provider pricing is commonly flat for download-heavy backup restores; confirm current terms before you commit.
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 can prevent normal deletion of objects during a retention period. If your bucket supports it, macup can use compliance-mode Object Lock and show that stronger ransomware-resistance layer. If your bucket doesn't, backup still works but you lose that specific protection.
Can I switch providers later?
Yes. macup can export your repository to a different provider. Historical snapshots remain readable during the migration window, and you can run two providers in parallel while you move.
What if I run my own MinIO on a NAS?
That can work well. Enable Object Lock when you create the MinIO bucket if you want the stronger retention layer; otherwise treat it as fast local storage, not an off-site locked copy.
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.
