Intelligent backups with dynamic proxy in virtualized environment

A non-transitory computer-readable medium programmed with executable instructions that, when executed by a processing system having at least one hardware processor;

• perform operations comprising:
• setting a polling timer interval for initiating polling;
• periodically polling a virtual machine host according to the polling timer interval to determine a plurality of virtual machines configured on the virtual machine host and attributes about each of the plurality of virtual machines, including at least one of size of the virtual machine or a size of the data to be backed up for the virtual machine;
• determining a number of backup proxies configured for backing up the data of each of the plurality of virtual machines on the virtual machine host;
• generating a new backup proxy based on the plurality of virtual machines and the number of backup proxies, in response to a rule in a set of one or more rules indicating that the mapping ratio of the plurality of virtual machines to backup proxies exceeds a threshold value, or only one backup proxy is configured for backing up the plurality of virtual machines;
• automatically provisioning the new backup proxy based on a predetermined proxy template in response to the one or more rules indicating that the new backup proxy should be generated;
• automatically decommissioning one or more of the backup proxies in response to determining that a backup proxy is older than a threshold value of time, or a backup proxy uses an operating system that is outdated by a threshold number of revisions;
• spawning a replacement backup proxy to replace each backup proxy decommissioned due to being old or outdated in response to determining that the replacement backup proxy is needed;
• in response to a change in the plurality of virtual machines, generation of one or more new backup proxies, or decommissioning of one or more old/outdated backup proxies, storing an updated list of the virtual machines and the backup proxies and an updated mapping of the virtual machines to the backup proxies in a configuration database;
• and
• updating the polling timer interval by:
• determining a configuration change occurred more than once during a last polling;
• and
• decreasing the polling tinier interval to a minimum time interval value between two configuration changes during the last polling, wherein the configuration change comprises the change in the plurality of virtual machines, generation of one or more backup proxies or decommissioning of one or more old/outdated backup proxies.

A system comprising:

• a processing system having at least one hardware processor, the processing system coupled to a memory programmed with executable instructions that, when executed by the processing system, perform operations comprising:
• setting a polling timer interval for initiating polling;
• periodically polling a virtual machine host according to the polling timer interval to determine a plurality of virtual machines configured on the virtual machine host and attributes about each of the plurality of virtual machines, including at least one of a size of the virtual machine or a size of the data to be backed up for the virtual machine;
• determining a number of backup proxies configured for backing up the data of each of the plurality of virtual machines on the virtual machine host and a mapping ratio of virtual machines to the number of backup proxies;
• generating a new backup proxy based on the plurality of virtual machines and the number of backup proxies, in response to a rule in a set of one or more rules indicating that the mapping ratio of the plurality of virtual machines to backup proxies exceeds a threshold value, or only one backup proxy is configured for backing up the plurality of virtual machines;

• outdated backup proxies, storing an updated list of the virtual machines and the backup proxies and an updated mapping of the virtual machines to the backup proxies in a configuration database;
• and
• updating the polling, timer interval by:
• determining a configuration change occurred more than once during a last polling;
• and
• decreasing the polling timer interval to a minimum time interval value between two configuration changes during the last polling, wherein the configuration change comprises the change in the plurality of virtual machines, generation of one or more backup proxies or decommissioning of one or more old/outdated backup proxies.
