System and method for a backup data verification for a file system based backup
A method for verifying data includes obtaining, by a backup agent, a backup verification trigger for a backup stored in a backup storage system, in response to the backup verification trigger, obtaining backup metadata associated with the backup, performing a hierarchical structure data mapping based on the backup metadata to obtain a hierarchical structure associated with the backup, performing, using the hierarchical structure, a backup verification to generate a backup health state of the backup, after the backup verification is generated: making a determination, based on the backup verification, that the backup health state is not in a healthy state, and in response to the determination, performing a remediation of the backup policies.
1. A method for managing a persistent storage system, the method comprising:
obtaining, by a backup agent, a backup verification trigger for a backup stored in a backup storage system;
in response to the backup verification trigger,
obtaining backup metadata associated with the backup;
performing a hierarchical structure data mapping based on the backup metadata to obtain a hierarchical structure associated with the backup;
performing, using the hierarchical structure, a backup verification to generate a backup health state of the backup;
after the backup verification is generated:
making a determination, based on the backup verification, that the backup health state is not in a healthy state; and
in response to the determination, performing a remediation of the backup policies.
2. The method of claim 1 , wherein the backup metadata is stored in a backup storage metadata repository.
3. The method of claim 2 , wherein the backup metadata storage repository is a secondary storage system separate from the backup storage system.
4. The method of claim 2 , further comprising:
obtaining a backup generation request for a file system;
performing, in response to the backup generation request, a backup generation to obtain the backup;
generating a backup token based on the backup;
storing the backup in the backup storage system; and
storing the backup token in the backup storage metadata repository.
5. The method of claim 4 , further comprising:
after storing the backup in the backup storage system, obtaining the backup token from the backup storage metadata repository;
generating a second backup token using data stored in the backup;
comparing the backup token and the second backup token;
making a second determination that the backup token and the second backup token do not match; and
in response to the second determination, performing a second remediation of the backup.
6. The method of claim 1 , wherein the backup metadata comprises a backup token, file system information, and backup data storage location associated with backup data of the backup.
7. The method of claim 1 , wherein performing the remediation comprises changing the next scheduled backup to a full backup.
8. A system, comprising:
a processor; and
memory comprising instructions which, when executed by the processor, perform a method, the method comprising:
obtaining, by a backup agent, a backup verification trigger for a backup stored in a backup storage system;
in response to the backup verification trigger,
obtaining backup metadata associated with the backup;
performing a hierarchical structure data mapping based on the backup metadata to obtain a hierarchical structure associated with the backup;
performing, using the hierarchical structure, a backup verification to generate a backup health state of the backup;
after the backup verification is generated:
making a determination, based on the backup verification, that the backup health state is not in a healthy state; and
in response to the determination, performing a remediation of the backup policies.
9. The system of claim 8 , wherein the backup metadata is stored in a backup storage metadata repository.
10. The system of claim 9 , wherein the backup metadata storage repository is a secondary storage system separate from the backup storage system.
11. The system of claim 8 , the method further comprising:
obtaining a backup generation request for a file system;
performing, in response to the backup generation request, a backup generation to obtain the backup;
generating a backup token based on the backup;
storing the backup in the backup storage system; and
storing the backup token in the backup storage metadata repository.
12. The system of claim 11 , the method further comprising:
after storing the backup in the backup storage system, obtaining the backup token from the backup storage metadata repository;
generating a second backup token using data stored in the backup;
comparing the backup token and the second backup token;
making a second determination that the backup token and the second backup token do not match; and
in response to the second determination, performing a second remediation of the backup.
13. The system of claim 8 , wherein the backup metadata comprises a backup token, file system information, and backup data storage location associated with backup data of the backup.
14. The system of claim 8 , wherein performing the remediation comprises changing the next scheduled backup to a full backup.
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, the method comprising:
obtaining, by a backup agent, a backup verification trigger for a backup stored in a backup storage system;
in response to the backup verification trigger,
obtaining backup metadata associated with the backup;
performing a hierarchical structure data mapping based on the backup metadata to obtain a hierarchical structure associated with the backup;
performing, using the hierarchical structure, a backup verification to generate a backup health state of the backup;
after the backup verification is generated:
making a determination, based on the backup verification, that the backup health state is not in a healthy state; and
in response to the determination, performing a remediation of the backup policies.
16. The non-transitory computer readable medium of claim 15 , wherein the backup metadata is stored in a backup storage metadata repository.
17. The non-transitory computer readable medium of claim 16 , wherein the backup metadata storage repository is a secondary storage system separate from the backup storage system.
18. The non-transitory computer readable medium of claim 16 , the method further comprising:
obtaining a backup generation request for a file system;
performing, in response to the backup generation request, a backup generation to obtain the backup;
generating a backup token based on the backup;
storing the backup in the backup storage system; and
storing the backup token in the backup storage metadata repository.
19. The non-transitory computer readable medium of claim 18 , the method further comprising:
after storing the backup in the backup storage system, obtaining the backup token from the backup storage metadata repository;
generating a second backup token using data stored in the backup;
comparing the backup token and the second backup token;
making a second determination that the backup token and the second backup token do not match; and
in response to the second determination, performing a second remediation of the backup.
20. The non-transitory computer readable medium of claim 15 , wherein performing the remediation comprises changing the next scheduled backup to a full backup.
