Secure, Reliable, Recovery. Since 2002

eSilo provides offsite backup and data storage that uses a secured internet connection to archive files, databases and emails in our world-class data centers. eSilo uses UltraZip compression and is able to reduce backup times and overall storage costs for clients. eSilo backups are automatic, affordable, incremental and provide you with a solid disaster recovery and business continuity plan. All data backed up with eSilo is encrypted
with 256-bit AES encryption.


There is no mystery about whether an organization should backup their data, although how that should be accomplished remains in dispute. One undisputed fact is that vital data cannot remain onsite, thus requiring a means of transport to a second location. The goal is to cost-effectively, securely and reliably transport information off-site to protect businesses from data loss. Recent natural disasters and regulations have made everyone think twice about managing their backups locally.


256-bit AES encryption for all communications and stored data.


Data is Stored at Multiple Data Centers ensuring Redundancy.


eSilo’s UltraZip gets compression ratios as high as 90%.


Store an unlimited number of revisions and restore files to exactly how they were on day "X"


Set and forget it technology. No tapes, no equipment and no hassles.


No licenses, setup charges or software costs. Pay for what you store.

Data Backup and Storage Provider Since 2002

eSilo's backup technology was designed with security as a priority. All data sent to eSilo is encrypted prior to transfer, with a private customer key, and is sent through an encrypted internet connection. We use 256-bit AES encryption for data and communications which is simply unbreakable.

Not only is your information safe from prying eyes, eSilo uses the internet as the vehicle of transportation. This is far more reliable and efficient than other forms transport: such as plane or truck. No one can "steal" your data along the way, like one could if you shipped tapes. Moving at fiber optic speeds beneath land or sea, eSilo secures your data in redundant locations.

Backup Agents

Standard Edition

The Standard edition is designed to backup mapped drives and is normally used on workstations and laptops, although it can be used on servers. The computer must remain logged in during the backup.

Server Edition

The Server edition can execute backups while the computer is logged out of Windows. It can be used on workstations as well, despite its name, but is more commonly used for servers that remain logged out for security reasons. This edition cannot backup mapped drives.

Exchange Edition

The Exchange edition is a special Microsoft Exchange plugin that talks directly with the exchange server. You are presented with a list of mailboxes, and their contents, to select for backup. You have the ability to restore individual emails, contacts, calendar entries or any other type of exchange item. The exchange server continues to run while a backup is occurring. There is no downtime.

Linux/Unix Edition

The Unix & Linux edition has been tested on Linux 2.2 kernels and above. If you have a platform not currently supported, eSilo will assign a software engineer to provide you with an agent. There is no Graphical Interface for this edition. Schedules are conf files and cron is used to fire backups.

Backups and Restores Made Simple by Design.

eSilo has backup agents that provide simple navigation, schedule management and drag-n-drop backups. As shown in the application screenshot, eSilo has a simple file tree interface allowing you to check off the files/folders for backup or restore. Files can also be dragged and dropped between the "Local Files" and "My Silo" trees.

The backup agent applications are normally used to create backup schedules or to perform restores. Backup schedules are what make eSilo hands free. Email backup reports give eSilo users a detailed overview of all agent backups across their storage silo.

The eSilo backup agents were designed to have a very small impact on your computer. A scheduled backup uses about 6% of your CPU and an average of 4 MB RAM. Most customers do not notice when a scheduled backup is running. To avoid fragmenting your disk drive, backup agents do not use your disk drive for temporary storage. Instead, the files to backup are read into RAM, compressed, encrypted and then sent to our Tier 1 data centers.

eSilo Storage Silo Tree

On-Site Convenience.

Off-Site Protection.

eSilo offers a suite of server-end licensed software applications allowing you to serve your own backup clients with the optional ability of synchronizing data to one of our facilities or one of your own. Housing your own backup servers allows you to reuse existing storage systems, provides for local (faster) restores and keeps all data within your organization.

SILOServ is the heart of the eSilo Backup System. This is the server-side backup application that eSilo backup agents communicate with. Handling  All authentication, secure connections, archiving logic, volume management, data warehousing and system logging. SILOServ™ is an extremely scalable application that can serve tens of thousands of backup clients simultaneously.

When you purchase a license for SILOServ, our server technicians fully administer, monitor, update and support the server for the life of the license. We do all of this work remotely, providing onsite support if purchased, and have technicians on call 24/7 365. From your perspective, an eSilo server is a device within your network that just works; no administration or configuration is required on your end. eSilo can provide the hardware for the server or you can utilize your own.  Contact  eSilo now to learn more and/or get in touch with a Storage Expert.

SILOServ™  can reuse existing storage within your network as backup volumes. DAS, NAS, SAN or internal storage can be used. Being a heterogeneous application, it can communicate with any device from any vendor. If such storage does not exist, eSilo can provide the required storage or work with you on a storage plan.


SILOSync allows a set of eSilo servers to synchronize data between themselves. SiloServ™ servers are normally configured in sets of two, a master and a remote slave. The purpose is to keep the slave updated throughout the day; similar to replication. The slave is designed to take over as master in the event the master becomes unavailable. SiloSync can also be used to synchronize other data in your network to any location in the world.


SILOManager  is used to manage a running  SILOServ™  server and as well as displays statistics. Some features are:

  • Account listing (reseller enabled)
  • Currently logged in eSilo users
  • Storage Stats for each account and user
  • Billing Information (reseller enabled)
