Method and system for generating synthetic backups using pseudo-asset backups
A method that is performed for backing up data. The method includes obtaining an incremental backup request; and in response to the incremental backup request: obtaining an asset and an asset entry associated with the incremental backup request; dividing the asset into pseudo-assets based on the asset entry; storing the pseudo-assets across backup storages to generate incremental pseudo-asset backups; initiating the merging of the incremental pseudo-asset backups to generate an incremental asset backup; and initiating the merging of the incremental asset backup with a previously generated full asset backup associated with the incremental backup request to generate a first synthetic full asset backup.
1. A method for backing up data, the method comprising:
obtaining an incremental backup request; and
in response to the incremental backup request:
obtaining an asset and an asset entry associated with the incremental backup request;
dividing the asset into pseudo-assets based on the asset entry;
storing the pseudo-assets across backup storages to generate incremental pseudo-asset backups;
initiating merging of the incremental pseudo-asset backups to generate an incremental asset backup; and
initiating merging of the incremental asset backup with a previously generated full asset backup associated with the incremental backup request to generate a first synthetic full asset backup.
2. The method of claim 1 , wherein the asset entry comprises:
change information, specifying portions of the asset that have been modified since the generation of the previously generated full asset backup.
3. The method of claim 2 , wherein the asset comprises folders that have been modified since generation of the previously generated full asset backup.
4. The method of claim 1 , wherein each pseudo-asset comprises a portion of the asset.
5. The method of claim 4 , wherein the previously generated full asset backup may be one selected from a group consisting of a full asset backup or a second synthetic backup.
6. The method of claim 1 , wherein the first synthetic full asset backup comprises:
asset data associated with the previously generated full asset backup;
modified asset data associated with the incremental asset backup;
asset backup metadata associated with the previously generated full asset backup; and
at least a portion of the asset entry.
7. The method of claim 1 , wherein each pseudo-asset backup comprises:
a portion of asset data of the asset corresponding to the pseudo-asset; and
a portion of the asset entry corresponding to the portion of the asset data.
8. A system for backing up data, comprising:
a processor;
a backup agent, which when executed by the processor performs a method, the method comprising:
obtaining an incremental backup request; and
in response to the incremental backup request:
obtaining an asset and an asset entry associated with the incremental backup request;
dividing the asset into pseudo-assets based on the asset entry;
storing the pseudo-assets across backup storages to generate incremental pseudo-asset backups;
initiating merging of the incremental pseudo-asset backups to generate an incremental asset backup; and
initiating merging of the incremental asset backup with a previously generated full asset backup associated with the incremental backup request to generate a first synthetic full asset backup.
9. The system of claim 8 , wherein the asset entry comprises:
change information, specifying portions of the asset that have been modified since the generation of the previously generated full asset backup.
10. The system of claim 9 , wherein the asset comprises folders that have been modified since generation of the previously generated full asset backup.
11. The system of claim 8 , wherein each pseudo-asset comprises a portion of the asset.
12. The system of claim 11 , wherein the previously generated full asset backup may be one selected from a group consisting of a full asset backup or a second synthetic backup.
13. The system of claim 8 , wherein the first synthetic full asset backup comprises:
asset data associated with the previously generated full asset backup;
modified asset data associated with the incremental asset backup;
asset backup metadata associated with the previously generated full asset backup; and
at least a portion of the asset entry.
14. The system of claim 8 , wherein each pseudo-asset backup comprises:
a portion of asset data of the asset corresponding to the pseudo-asset; and
a portion of the asset entry corresponding to the portion of the asset data.
15. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for backing up data, the method comprising:
obtaining an incremental backup request; and
in response to the incremental backup request:
obtaining an asset and an asset entry associated with the incremental backup request;
dividing the asset into pseudo-assets based on the asset entry;
storing the pseudo-assets across backup storages to generate incremental pseudo-asset backups;
initiating merging of the incremental pseudo-asset backups to generate an incremental asset backup; and
initiating merging of the incremental asset backup with a previously generated full asset backup associated with the incremental backup request to generate a first synthetic full asset backup.
16. The non-transitory computer readable medium of claim 15 , wherein the asset entry comprises:
change information, specifying portions of the asset that have been modified since the generation of the previously generated full asset backup.
17. The non-transitory computer readable medium of claim 16 , wherein the asset comprises folders that have been modified since generation of the previously generated full asset backup.
18. The non-transitory computer readable medium of claim 15 , wherein each pseudo-asset comprises a portion of the asset.
19. The non-transitory computer readable medium of claim 18 , wherein the previously generated full asset backup may be one selected from a group consisting of a full asset backup or a second synthetic backup.
20. The non-transitory computer readable medium of claim 15 , wherein the first synthetic full asset backup comprises:
asset data associated with the previously generated full asset backup;
modified asset data associated with the incremental asset backup;
asset backup metadata associated with the previously generated full asset backup; and
at least a portion of the asset entry.
