- 2. Agentless Backup is Not a Myth. The Asigra solution requires no agents, which inherently makes it easier to install and support than other backup and recovery solutions. Backup and recovery software typically requires agents that are installed onto the servers that a system administrator wants to back up. Even in a modest-sized environment, agent management can become extremely complex when an administrator is forced to deal with different operating systems and revision levels. The complexity of agent management is further complicated by the growing number of applications that also require agents running on the same servers. This proliferation of agents and its associated drain on CPU resources is often referred to as “agent pollution”. Asigra does not require any agents to be installed but instead reaches out over the network to back up operating systems, file systems, and applications, using industrystandard programming interfaces. To understand how Asigra backs up data over a network without the use of agents, consider how a local hard drive on a typical PC can be accessed remotely. A system administrator only needs the right permissions to access that local hard drive over the network. A disk-to-disk backup is performed by simply copying the contents of the hard drive to another hard drive on the network. Asigra software uses a sophisticated extension of this idea, unlike other software that requires agents on every machine. The Asigra solution is simple and elegant in concept, but required a lot of hard work and years of development to get it right on a broad variety of operating systems and data types. Why This Matters Dealing with backup software agents is a cumbersome and mundane task that can be extremely time consuming. Matching agent revisions with operating system levels, researching compatibility issues, and other labor-intensive tasks are non-existent when using the Asigra solution. Additionally, many problems that occur while managing backup software in complex environments are due to compatibility issues with agents. Compared to other solutions, Asigra’s agentless design is inherently easier to support and the risk of problems is reduced. Finally, agents rob processing power from the core applications of every machine on which they’re installed. Asigra makes no such demands on the servers it is backing up. Multiplied over thousands of machines, that extra power efficiency can mean significant savings and greener operations.

IT managers know the downsides that accompany agentbased solutions: Compromised security. A port in the firewall must be opened for every agent. And, because almost every agent has administrative privileges, it effectively creates vulnerability in the server architecture. Hackers need only to tap into the agent to attack the server. With no “in-flight” encryption, agents also put data at risk during transmission from the remote office to the data center. More pieces of software to manage and to fail.

As infrastructure expands in size and complexity, problem diagnosis takes longer. Every operating system upgrade (now implemented monthly by many organizations) creates more opportunities for conflicts amongst applications, including proliferating backup agents. The fact is backup agents drain IT resources, cause disruptive downtime, and, ultimately, undermine the certainty of data recoverability. Exorbitant licensing fees. Traditional software vendors charge for software based on the old per-system model. This is costly and requires customers to closely monitor their complex system and user landscapes. For many growing organizations, buying a site license is actually a simpler solution — albeit even more costly and often unnecessary — than trying to keep track of backup Icomm Techonogies 3755 Camden Street, Birmingham, B1 3BP United Kingdom Tel: 0121 248 7931 Email: salesr@icomm.co.uk

There are even consulting companies that now do audits to help enterprises lower license fees. print servers, email servers, databases, and workstations.

Heterogeneous applica- Application Disruption.

It takes time and a lot of ‘touching’ of remote-site systems to push agents and upgrades out to every server. And each time a data center administrator or service provider has to deploy an agent, or intervene to support it at a remote site, that cost rolls back into the business model making it increasingly difficult to remain competitive. version of the software is released, the agents must be upgraded too. This upgrade process requires a reboot of the server that the agent resides on. Unfortunately, this application disruption must be repeated for every affected server on the network. With Asigra, there is no application disruption. Asigra agentless client software is dispatched and upgraded silently with no need for a server reboot. How does it work? As the industry’s only agentless, multi-site backup and recovery software solution, Asigra technology completely eliminates the negative impact of agents. How does it work? To put licensing and administrative costs in perspective, an enterprise with as few as five offices can easily spend $50,000 to purchase and maintain backup agents for file/ CLOUD STORAGE Direct Attached (SATA) ARCHIVE STORAGE BLM Archiver Cloud Storage Production DS-License Archive Data Destruction with Certificate Web Portal DS-Billing NAS DS-System MS CU STO ME PP RIM LO TU S IN T HY ANG PE E RV M AREPO IB MS SH F Windows DS-Client IL SQ E SER EX L D VER CH B LOCAL/ LOCAL-ONLY AR YD ATA C EN TER IP WAN RA (PU BL IC LOCAL/ LOCAL-ONLY CL OU D) Linux DS-Client RE MO TE US IB CL Xe M 0 E nS B2 erv er UN VM IX IB wa M re OR AS40 A 0 DS-Mobile Client ER (S) CU STO ME RB Initial Backup to External Digital Media Icomm Techonogies 3755 Camden Street, Birmingham, B1 3BP United Kingdom Tel: 0121 248 7931 Email: salesr@icomm.co.uk ONLINE STORAGE
- 6. The Asigra architecture consists of two software components: the DS-Client and the DS-System. DS-Client software, installed on one server (Windows, Macintosh, or Linux) at each local and remote site, captures data from its target backup machines. The DS-Client then processes the data to reduce its size (compression and deduplication), encrypts it for security, and then transmits the data via IP WAN to the DS-System at the storage location. The DS-Client does not require installation of any backup agents on its target machines. The DS-Client fully integrates with NT domains, Trusts and Novell NDS trees, and otherwise adopts the remote site’s existing LAN security settings. Using standard APIs, the DS-Client can remotely log in to target backup systems, capture requested data, and securely manage transmissions to the central site. Utilizing common data reduction technologies, the DS-Client minimizes the amount of data transmitted and stored at the onsite or off-site vault. The DS-System manages the storage repository for backup data transmitted from one or multiple DS-Clients. The DS-System (configured as direct-attached disk, NAS or SAN) can be installed on Linux and Windows platforms. Asigra software integrates a comprehensive feature set designed to maximize and accelerate data recoverability. An Autonomic Healing module, for example, runs seamlessly in the background to identify and isolate corrupt or otherwise problematic files. As an added value, if a corrupt file is found to be irreparable, it is tagged to be re-transmitted on the next scheduled backup. Another feature, the Local Restore tool, allows remote-office storage of backup data. This ensures that local users can restore critical data immediately and at LAN speed. Additional Asigra tools include an Online File Summary, Long Term Storage policy-making, a Discovery Tool to automatically ascertain characteristics of primary data, Email Message Level Restore, Bare Metal Restore capability, Client and System Monitoring, and SNMP Integration. Why it works? The Asigra software eliminates the requirement for locally installed agents because it leverages the protocols, APIs, methods and functionality that platform, operating system, database, and other application vendors utilize for remotely managing their own systems. Other backup/ restore solutions require a unique backup agent (installed on every target machine) for each type of system and application. Asigra, however, supports all major platforms and applications with a software system composed of just two major components: the DS-Client (one installed at each site) and the DS-System (installed at the vaulting location). Another advantage of the Asigra software is that it enables multi-level access controls. The Benefits of Agentless: Reduce Costs, Robust Security, Simpler Scaling. At installation, the DS-Client is assigned privileges to establish access rights that meet the requirements of the site or organization. For example, the DS-Client might be assigned multiple credentials for the same network to allow the domain administrator to back up all systems, including servers and workstations, while enabling users to control the backups of individual workstations. The Asigra software has also been highly optimized to conserve both LAN and target-system CPU resources. Implementing an Asigra backup/recovery solution produces immediate and dramatic benefits. Significant savings. Even if backup agents from other vendors were free, the Asigra solution would still provide huge savings. First-year operating expenses alone approach an estimated $150,000 for an enterprise environment with 1,000 server agents. Annual server maintenance and operating expenses for this same configuration add up to nearly $60,000. The agentless Asigra solution eliminates those operating costs in addition to the purchase price of the agents. Simple licensing. DS-Client licenses ARE free. Asigra offers businesses a unique pay-as-you-grow pricing model based simply on the amount of compressed backup data Icomm Techonogies 3755 Camden Street, Birmingham, B1 3BP United Kingdom Tel: 0121 248 7931 Email: salesr@icomm.co.uk
- 7. stored. Customers purchase Asigra software the same as disk capacity — no license fees, no tracking, no overspending on site licenses — paying only for compressed storage capacity consumed. One piece of software to install, manage, and diagnose. Asigra software even upgrades itself, so there are no time-consuming and resource-draining updates required for the hundreds or perhaps thousands of systems on typical enterprise networks. WAN/LAN/CPU resource conservation. Asigra software runs with negligible impact on servers, workstations, and laptops, eliminating the drain on CPU resources associated with agent-based solutions. Data reduction technologies also minimize the impact on bandwidth and storage resources. While traditional agent-based backup/ recovery solutions require implementation of high-speed connections between the central data center and remote offices, Asigra works with existing links such as DSL. Robust, hardcoded security. Asigra software provides extremely safe ‘in-flight’ and ‘at-rest’ data security utilizing up to 256 bit AES encryption. And it works within the organization’s security framework—there are no agents to open hacker-tempting ports in the firewall. With secure data transmission across an IP WAN, the Asigra solution helps businesses achieve compliance, minimize information-loss liabilities, and protect customer confidence. ‘Elegant’ scaling. The DS-System is capable of elegantly scaling both in the dimensions of capacity and performance. This type of scalability is critical for environments with large numbers of remote sites, high-capacity data sets, and rapid data growth. While agent-based solutions compound complexity in rapid growth environments, the Asigra agentless backup/recovery solution easily accommodates new capacity, new applications, and new sites. Features such as integrated load balancing ensure efficiency across multiple DS-System IP addresses. Backup consistency, improved recoverability. The simplicity, efficiency, and security of the Asigra system makes it easy for remote sites to implement and maintain consistent data backup programs. This means companies can significantly boost data recoverability in locations where success rates below 50% were once the norm.
