Cloud backup services become operational using collector software. Collector software can be “agent based” or “agentless”. Agent based collector software systems require the download and installation of the collector software on every single machine that will be linking up to the cloud backup account of the subscribing organization. Agentless collector software systems require the software to be downloaded and installed on a single machine that acts like a collector to all other machines connecting to the online cloud backup account. While both systems have their advantages and disadvantages, agentless software systems are preferred for their flexibility, scalability and efficiency.
The collector in an agentless architecture can be updated independent of the environment in which it operates. The component information is leveraged system wide without pausing or disrupting operative services. Administrative overheads are also lowered as the architecture maintains accurate data by constantly and automatically monitoring applications and updating reports on activities being performed by the system even if the client is offline. Complexity is stripped from storage in cloud backup systems and the user interface remains friendly to the end user despite updates and enhancements that are being made at the backend.
The agentless collector software centralizes the definitions of files, compiles the element combinations and pertinent configurations for backup to the cloud. The collected knowledge is then applied to multiple data streams that are piped through the central system on the way to the cloud backup repository–easing the process of deduplication, compression or encryption of information.
The advantages of agentless collector architecture for cloud backup can be summarized as under:
1. Agentless cloud backup architectures eliminate downtime or service disruptions. The software has to be installed on a single machine and all other machines can be connected to it over a LAN or WAN. All upgrades to the software can be applied on the central node without disrupting data services or cloud backup services within the organization during the upgrade.
2. The agentless cloud backup system eliminates the need to manage multiple point solutions for data flowing in from different points on the enterprise network. Multiple nodes can connect to the central node and pipe their “raw” data to the through it for being processed for duplicates and subjected to encryption algorithms before being pushed into the cloud backup repository.
