Abstract

A backup agent for generating backups includes a persistent storage and a backup manager. The persistent storage stores backup/restoration policies. The backup manager obtains production host computing resource characteristics associated with production hosts; performs a computing resource analysis of the production host computing resource characteristics to obtain resource profiles for each of the production hosts; performs an availability analysis of the obtained resource profiles to determine an application-level computing resources distribution for generating the backups; coordinates generating the backups using the application-level computing resource distribution and the backup/restoration policies to obtain the backups; and stores the obtained backups in backup storage.

First claim

What is claimed is:

1 . A backup agent for generating backups, comprising:
a persistent storage that stores backup/restoration policies; and a backup manager programmed to:
obtain production host computing resource characteristics associated with production hosts;
perform a computing resource analysis of the production host computing resource characteristics to obtain resource profiles for each of the production hosts;
perform an availability analysis of the obtained resource profiles to determine an application-level computing resources distribution for generating the backups;
coordinate generating the backups using the application-level computing resource distribution and the backup/restoration policies to obtain the backups; and
store the obtained backups in backup storage.

2 . The backup agent of claim 1 , wherein the production host computing resource characteristics is a cardinality of a total number of processing cores of each respective production host.

3 . The backup agent of claim 1 , wherein performing the computing resource analysis of the production host computing resource characteristics to obtain resource profiles for each of the production hosts comprises:
identifying a maximum availability of a plurality of computing resources for each of the production hosts; and storing each respective plurality of computing resources in a corresponding resource profile of the resource profiles.

4 . The backup agent of claim 1 , wherein performing the availability analysis of the obtained resource profiles to determine an application-level computing resources distribution for generating the backups comprises:
identifying a limiting resource of each of the production hosts using the obtained resource profiles; determining a maximum number of concurrent backup generation sessions for each of the production hosts based on the identified limiting resource of each of the production hosts; and storing the maximum number of concurrent backup generation sessions for each of the production hosts as the application-level computing resources distribution.

5 . The backup agent of claim 1 , wherein coordinating the generating of the backups using the application-level computing resource distribution and the backup/restoration policies to obtain the backups comprises:
generating backup initiation instructions for each production host based on a corresponding policy of the backup/restoration policies and the application-level computing resource distribution; and sending the generated backup initiation instructions to corresponding production agents of the production hosts.

6 . The backup agent of claim 5 , wherein generating the backup initiation instructions for each production host based on the corresponding policy of the backup/restoration policies and the application level computing resource distribution comprises:
obtaining a first policy of the backup/restoration policies that corresponds to a first production host of the production hosts; identifying an administrator-specified maximum number of sessions of the first policy; identifying a first maximum number of sessions for the first production host specified by the application-level computing resource distribution; making a determination that the first maximum number of sessions is larger than the administrator-specified maximum number of sessions; and specifying the administrator-specified maximum number of sessions for the first production host in the backup initiation instructions.

7 . The backup agent of claim 5 , wherein generating the backup initiation instructions for each production host based on the corresponding policy of the backup/restoration policies and the application level computing resource distribution comprises:
obtaining a first policy of the backup/restoration policies that corresponds to a first production host of the production hosts; identifying an administrator-specified maximum number of sessions of the first policy; identifying a first maximum number of sessions for the first production host specified by the application-level computing resource distribution; making a determination that the first maximum number of sessions is smaller than the administrator-specified maximum number of sessions; and specifying the first maximum number of sessions for the first production host in the backup initiation instructions.

8 . The backup agent of claim 1 , wherein the backups are associated with applications executing on the production hosts.

9 . The backup agent of claim 1 , wherein the backup storage is separate from the backup agent.

10 . The backup agent of claim 9 , wherein the production hosts are separate from the backup storage.

11 . The backup agent of claim 1 , wherein the production host computing resource characteristics associated with the production hosts are obtained in response to a policy of the backup/restoration policies being triggered.

12 . The backup agent of claim 11 , where the policy of the backup/restoration policies is triggered by an occurrence of a predetermined event.

13 . The backup agent of claim 12 , wherein the predetermined event is a predetermined point in time.

14 . A method for generating backups, comprising:
obtaining production host computing resource characteristics associated with production hosts; performing a computing resource analysis of the production host computing resource characteristics to obtain resource profiles for each of the production hosts; performing an availability analysis of the obtained resource profiles to determine an application-level computing resources distribution for generating the backups; coordinating generating the backups using the application-level computing resource distribution and backup/restoration policies to obtain the backups; and storing the obtained backups in backup storage.

15 . The method of claim 14 , wherein performing the computing resource analysis of the production host computing resource characteristics to obtain resource profiles for each of the production hosts comprises:
identifying a maximum availability of a plurality of computing resources for each of the production hosts; and storing each respective plurality of computing resources in a corresponding resource profile of the resource profiles.

16 . The method of claim 14 , wherein performing the availability analysis of the obtained resource profiles to determine an application-level computing resources distribution for generating the backups comprises:
identifying a limiting resource of each of the production hosts using the obtained resource profiles; determining a maximum number of concurrent backup generation sessions for each of the production hosts based on the identified limiting resource of each of the production hosts; and storing the maximum number of concurrent backup generation sessions for each of the production hosts as the application-level computing resources distribution.

17 . The method of claim 14 , wherein coordinating the generating of the backups using the application-level computing resource distribution and the backup/restoration policies to obtain the backups comprises:
generating backup initiation instructions for each production host based on a corresponding policy of the backup/restoration policies and the application-level computing resource distribution; and sending the generated backup initiation instructions to corresponding production agents of the production hosts.

18 . A non-transitory computer readable medium comprising compute
