ZFS-powered incremental snapshots, automatic compression, and instant point-in-time restores — delivered as a managed service. Built entirely on open source.
Built on the same technologies that power hyperscalers — without the hyperscale price tag or the proprietary lock-in.
Every snapshot is a guaranteed-consistent point in time. ZFS copy-on-write means snapshots are instant — no I/O quiesce, no performance penalty, no data at risk during creation.
Only changed blocks ever transfer. A 1 TB dataset with 1 GB of daily changes costs you 1 GB of bandwidth per day — not 1 TB.
LZ4 compression runs at the block level before hitting disk. Typical workloads see 1.5–3× ratios. You're billed on compressed size.
Your storage node joins your own Tailscale mesh. Zero public ports, zero internet exposure. Every byte travels over WireGuard's modern cryptography.
Mount with sshfs, sync with rsync, or stream with ZFS send/receive. No proprietary client to install. Standard tools you already know and trust.
Daily and weekly snapshot schedules with per-plan retention counts. Browse any historical snapshot in the portal and restore with a single click.
No infrastructure to provision, no agents to babysit. Your backup storage is ready before your next coffee.
Pick the storage size and snapshot retention that fits your needs. Every plan starts with a 14-day free trial — card collected by Stripe, cancel any time before it ends.
Install the Tailscale client on your devices. Your dedicated storage node appears on your private network automatically — no firewall rules, no port forwarding.
Use rsync, SFTP, or ZFS send/receive. Automatic daily snapshots run on schedule whether you're connected or not. Restore any point in time from the portal in one click.
14-day free trial on every plan. No setup fees. No per-seat costs. Cancel any time.
Annual billing saves 2 months per year — billed once annually, overage invoiced monthly. · Full comparison & cost calculator → · Need more? Contact us for volume pricing.
Every component of our stack is open source and battle-tested. No black boxes. No proprietary binaries on your machines.
Copy-on-write, per-block checksums, built-in compression, and RAID-Z. Silent data corruption doesn't happen — it gets detected and repaired.
Modern VPN built on WireGuard's state-of-the-art cryptography. Tailscale adds mesh networking so your storage appears as a local device on any of your machines.
The tools you already know. SSH for secure shell access, SFTP for file browsing, rsync for efficient transfers. No custom agents, no vendor lock-in.
Rock-solid host OS with a well-understood security model and 5-year LTS support cycles. No exotic kernel modules, no custom patching — reproducible and auditable.
Full observability stack monitoring every storage node, transfer job, and snapshot operation. We watch so you don't have to — alerts fire before problems become incidents.
All account metadata, snapshot records, and billing state live in PostgreSQL. ACID guarantees mean your snapshot history and billing records are always consistent.
The technical details, the trade-offs, the open questions — answered honestly.
Capyzfs send/receive.zfs send -i snap1 snap2 streams only the delta — not the full dataset. A 1 TB dataset with 1 GB of daily changes transfers ~1 GB/day. rsync works similarly for file-level incrementals without ZFS at the source.14-day free trial on every plan. Full access from day one. No surprise charges.
