Data Transmission Rates
Delta Block Incremental backups
Regardless of your connection speed, typical nightly backups and file restores take just minutes using our patented compression
and Delta Block Incremental technologies to transfer only changes within files that changed since your last backup.
DFR: Save space, time & bandwidth
Our patented Duplicate File Recognition (DFR) technology prevents duplicate files from being transferred and stored. So if
you have identical files saved in multiple locations -- such as an email attachment in your inbox and in a folder on your
hard drive -- you avoid spending network time and backup space to store it during each backup.
Our software also recognizes common program and system files stored at our data centers to optimize your initial backups.
Superior Data Center Performance
Our industry-leading data centers are located on major Internet hubs, with redundant bandwidth using multiple providers
for superior reliability and performance with 99.99% historical uptime.
Unlike most of our competitors, rarely if ever do bottlenecks occur on our end. Both Tier 1 class data centers are located
on multiple backbones using GigE and OC3 connections.
Initial Backup Data Transfer Rates
Your first backup transfers all your selected data to our data centers. Subsequent backups take a fraction of the time as
they transfer only daily delta block changes.
For the larger plans or slower connections, we suggest letting the initial backup run over the weekend. You can also stop
the backup at any point and let it resume later where it left off.

- *Typical Internet Service Providers limit your upload bandwidth to just a fraction of their
advertised download speeds, especially with cable and satellite connections.
- Our backup software compresses your data before sending it to the data center. Actual compression varies
greatly by the type of file. (Zip files, video and graphics are usually already fully compressed; some text files can be
compressed up to 90%.)
- Full system backups may be faster because many common system files are already archived in our library and
do not need to be duplicated.
- These are very rough estimates and may vary by a factor of two or more depending on your ISP's actual upload
speeds.
- Other factors may affect your transfer speeds, including your computer's operating system, processing power
and memory; traffic on the your local network, your ISP and the Internet. Your actual connection speed may vary greatly and
may not be as high as your ISP claims.
