Slow File Transfers? It's Latency, Not Bandwidth.
Cross-platform Runs on Windows, Linux and macOS (Apple Silicon) — copy between any of them.
Traditional tools — FTP, Robocopy, SFTP — send a chunk of data, then stop and wait to be told it arrived. On a long link that wait is long, so your connection sits idle instead of working. uvCopy keeps the link busy, typically putting over 90% of the bandwidth you already pay for to work — as software, on the hardware you already own.
Why Your Transfers Are Slow — and Why More Bandwidth Won't Fix It
Copy a file between two sites and the sender loses control of the pace: it transmits a block, then waits for the other end to confirm it arrived. When the sites are far apart, that round trip takes a long time — and while it waits, the link does nothing. Tools like FTP, Robocopy and SFTP all work this way. It isn't your disk or your hardware. It's the waiting.
So teams do the obvious thing: buy a bigger line, faster network cards, or both. The transfer improves a little, the invoice improves a lot. The bottleneck was never the size of the pipe — it was the round-trip delay, and a fatter pipe doesn't make the distance shorter.
uvCopy changes the order of operations: several blocks are kept in flight at once, and when one is lost only that block is sent again. The link stays busy instead of idling, and you get the full speed you are already paying for. It runs as software on the machines you already own — no kernel changes, no new hardware, no network redesign.
Keeps The Link Working: No more idle connection — data keeps moving while acknowledgements are in flight.
Cheaper Than An Upgrade: Get more out of the circuit you already pay for instead of leasing a bigger one.
Nothing To Rip Out: No kernel changes, no appliance, no network redesign — it is software you install and run.
Automation Friendly: Works with your scripts and scheduled jobs, so big transfers stop being someone's manual task.
Cross-Platform: Windows, Linux and macOS (Apple Silicon). Send from any of them to any of them — mixed fleets included.
Common Enterprise Use Cases
Different jobs, same bottleneck: latency on the wire. uvCopy works at the protocol layer, so these transfers usually finish in a fraction of the usual time on the network you already own.
Data Center Migration
Move file shares and any other big files between facilities or colocation sites without waiting on slow WAN transfers to drag out the migration window.
Database Migration
Move full production database backups and dumps between sites in a fraction of the usual time, so your cutover fits into one overnight window instead of a weekend-long outage.
Batch Processing
Nightly and intraday batch feeds arrive on schedule even between high-latency sites, so downstream systems start on time instead of idling while they wait for files.
Big Data Ingestion
Keep log, event, and sensor files flowing into your warehouse or data lake as they are produced, so reports and dashboards never fall behind the business.
Cross-Region Sync
Keep replicas in different regions identical with fast, verified file replication: no new fiber links to build and no recurring carrier leases to renew.
Cloud Migration
Move data between cloud providers or from cloud to on-prem environments without losing time to slow, public-internet transfers or repeated retransmissions.
How uvCopy Keeps Your Link Full
Built For The Link You Have
Payloads are sized to suit the connection, so performance is the same whether jumbo frames are on or off. Nothing to tune on the network side.
Bandwidth Throttling
Set a ceiling on how much a transfer may use, so one large overnight copy never soaks up the whole line while the business is working.
Every Network Card, At Once
Multiple adapters are used together rather than one after another, so a single transfer can draw on every path the machine has.
Only Resend What Was Lost
Blocks that were dropped or corrupted are sent again automatically — the rest of the file carries on untouched, so nothing restarts from the beginning.
Same link. Lightyears apart in throughput.
Each packet crosses at the same speed in both lanes. The difference is how many stay in flight: uvCopy sends continuously instead of waiting for each acknowledgement, carrying far more data over the same link. If packet 02 is lost, only that packet is retried.
Illustrative behavior on a high-latency link. Actual throughput depends on distance, route, hardware, and link conditions.
Simple Pricing
Prices are shown in your local currency. Every transfer has two ends — an origin and a target — so licenses are sold in bundles rather than one at a time. Choose the term that fits your project: 30, 90, 180 or 360 days.
