What Rsync.net does
Rsync.net, Inc. is a privately held cloud storage provider founded in 2001 by John Kozubik and headquartered in Fairfax, California. The company delivers offsite backup, data storage, and remote encrypted file systems for Windows, Mac, and Linux users, built on a proprietary ZFS-based platform running on FreeBSD that is owned and operated by rsync.net rather than resold from a hyperscaler. Customers receive a UNIX filesystem accessible through any SSH-based tool — rsync, SFTP, SCP, Borg, Rclone, restic, git-annex — with server-side execution of UNIX commands, immutable point-in-time snapshots, raidz3 fault tolerance (99.9999% single-location resiliency), per-account chroot isolation, 10 gigabit global networking, and IPv6 support across five data centers in Fremont, Denver, Zurich, and Kowloon.
The company monetizes primarily through pure subscription storage pricing of $0.006-$0.012 per GB per month, with volume discounts for 100TB+ and 1PB+ accounts, no setup fees, no contracts, and no overage or bandwidth charges. Distribution is direct-to-consumer and product-led: customers self-serve through a web-based account manager or contact the company by phone or email; ISPs, VARs, and consultants can white-label the service through a reseller program with billing automation. Physical media shipping is offered for initial seeding or disaster recovery, free for 100TB+ accounts.
Rsync.net targets technical enterprises, IT departments, HIPAA-regulated healthcare entities, NAS backup users, and UNIX/Linux power users and system administrators — buyers who value open standards, command-line workflows, and regulatory compliance over GUI-driven convenience. The customer base spans thousands of accounts in nearly every country, including marquee references such as 3M, Disney, ESPN, VMware, ARM, Columbia University, and Seattle Public Schools. Growth is driven entirely by word-of-mouth, community discussion, press coverage, and engineer-to-engineer recommendations; the company has no formal sales team and discloses no external funding.

Revenue model
- Cloud Storage (Offsite Backup): Pure storage-based pricing with no setup fees, no contracts, and no charges for usage, transfer, bandwidth, or concurrency. Revenue is driven by storage quota size contracted per account.
- Reseller Program: Resellers (ISPs, VARs, consultants) pay for storage consumed by their clients at metered rates. Resellers can fully white-label the product and set their own pricing. No setup or per-seat fees for resellers.
- Physical Media Delivery: Physical media shipment for initial seed data population or disaster recovery. Free for accounts 100TB and larger (two shipments per year); $250 per incident plus shipping and media costs for smaller accounts.

Rsync.net product offering
Product offeringCore offering
Rsync.net provides ZFS-based cloud storage for offsite backup, giving customers an empty UNIX filesystem accessible via any SSH-based tool (rsync, sftp, scp, borg, rclone, restic, git-annex). The platform delivers petabyte-scale namespaces, immutable point-in-time snapshots for ransomware protection, and geo-redundant replication across five global datacenters. The service runs on company-owned FreeBSD infrastructure (not a reseller of another cloud) and is offered to technical businesses, IT departments, healthcare providers, and individual power users.
Product overview
rsync.net offers a single, unified cloud storage product for offsite backup built on a proprietary ZFS platform. The core offering is a UNIX filesystem accessible via any SSH/SFTP tool, providing petabyte-scale storage with immutable point-in-time snapshots. The product is available in two tiers: Standard (single-location) and Geo-Redundant (automated secondary replication to a second global datacenter). Additional offerings include a White-Label Reseller Program with billing automation and provisioning API, a free Windows Backup Agent with block-level copying and AES-256 encryption, and Physical Data Migration services for large initial seed transfers. No other products or services are offered — the company has operated on a single-product focus since 2001.

Rsync.net competitors and assessment
Company assessmentDirect peers
- Backblaze: Backblaze B2 offers S3-compatible cloud storage priced similarly to rsync.net, targeting backup use cases for individuals, SMBs, and developers. Closest direct competitor given the shared focus on affordable backup-grade cloud storage with no egress fees on the B2 product line.
- Wasabi Technologies: Wasabi provides hot cloud storage with no egress fees and a pricing model directly competing with rsync.net's transparent volume-based model. Both target backup and archival workloads at substantially below hyperscaler pricing.
- Hetzner Storage Box: Hetzner offers SSH/SFTP-accessible backup storage boxes with a very similar technical model to rsync.net. Both serve UNIX-fluent users seeking low-cost, command-line-friendly offsite backup without graphical interfaces.
- Linode Object Storage: Linode (now Akamai) provides S3-compatible object storage targeting developers and SMBs at competitive pricing. Comparable developer-focused audience and similar backup use cases as rsync.net's UNIX engineering customer base.
- IDrive: IDrive offers cloud backup services for individuals and businesses, including an e2 for business backup product. Comparable backup-first positioning with a broader SMB-friendly GUI client, representing a more accessible alternative to rsync.net's CLI model.
- Vultr Object Storage: Vultr offers S3-compatible object storage aimed at developers and small businesses at low per-GB pricing. Similar target buyer (technical, self-serve, SSH/S3 literate) and overlapping backup and archival use cases.
Broad incumbents
- Amazon S3: Amazon S3 is the dominant cloud object storage service and the primary market benchmark for storage pricing. rsync.net explicitly markets itself as cheaper than S3, making S3 the principal competitive reference point though it serves a much broader workload portfolio.
- Microsoft Azure Blob Storage: Azure Blob Storage competes for the same enterprise backup and archival workloads as rsync.net, particularly within Microsoft-centric IT shops requiring HIPAA/SOX/PCI compliance — overlapping certifications rsync.net offers.
- Google Cloud Storage: Google Cloud Storage competes in the same enterprise backup and archive market as rsync.net, with broad multi-region presence and aggressive pricing on cold and archival tiers. Larger portfolio but overlapping backup use case.
Emerging players
- Storj: Storj is a decentralized cloud storage provider using a distributed node network to deliver S3-compatible object storage at competitive pricing. Emerging alternative for backup workloads that overlaps with rsync.net's market but uses a fundamentally different architectural model.
