Ideastack Offers Host Based Backup

Posted by shazim on 13 02 2017. 0 Comments

Host-based backup, mostly comes in two types, known as Agentless Backup and Agent-based Backup is a new whir in the field of data recovery. People usually know the agents as small applications installed in the host sever to run particular functions in a specific manner. These applications (agents) are installed on the host sever that the admin requires to backup. Agentless backup is the backup without the use of such agents. Whereas, Agent based backup is backing up of the information withe help of an agent or more.

Quite a few vendors claiming that they provide agentless backup, actually add an agent at the beginning of the process and delete it right before the entire backup is made. Surely the rest of the process does not involve any agents but, at the end you would not call it an agentless backup.

Need of Agent-based Backup

When choosing Agent-based backup as a service, you would have to reboot your system after the install because the snapshot driver resides at the operating system kernel level and hence requires the OS to be restarted. A plus point of agent based backup is, since it is loaded in the OS stack, it offers increased control and visibility of the host system that would not be immediately available in the case of Agentless backup. For example, agent-less backups typically need to traverse the file system to determine changes for incremental/differential backups. This traversel could take longer and be more complex than compared to Agent-based backup which has CBT (Change Block Tracking) and the kernel level.

Agent-based backups rely on local resources to compress and pre-process data before transmitting data across the network to the storage device (NAS/SAN, local USB drive, or remote host). In comparison, Agentless backups rely more on network resources to transmit application commands accross the network as well as data between the target and storage device. If your local network bandwidth is hardly enough to fulfill your needs, then additional network traffic from agent-less backups could impact local network performance.

R1 Soft

The Software we provide is R1 Soft Server Backup Manager. It is a near continuous backup application for Windows and Linux computers. It provides user scheduled near continuous disk-based online backups for more than one Windows or Linux servers. Every time a user scheduled backup is acted out, Delta Encoding deltas are transmitted to a backup archive efficiently creating a virtual Disk Image. Continuous Data Protection can restore previously captured disk images to another disk efficaciously replicating the structure and contents to a new disk. Individual files inside of a disk image can be restored to their original location or an alternate computer.
