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 via
multiple providers for superior reliability & performance with 99.99%
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.
