SYSTEM AND METHOD FOR RESTORATION USING MICRO-BACKUPS
A backup management system for providing data integrity services to an application host that hosts an application having application data includes storage for storing a restore point catalog and a processor programmed to obtain a micro-backup of the application, wherein the micro-backup reflects changes made to the application data over a period of time from when a last scheduled backup was generated and a number of changes to the application data exceeded a predetermined number, wherein generation of the micro-backup was not scheduled; obtain a timestamp that delineates an end of the period of time; obtain header data of the last scheduled backup generated for the application host; and obtain an application backup for the application using the micro-backup, the timestamp, and the header data, wherein the application backup is usable to restore the application to a state associated with the end of the period of time.
1 . A backup management system for providing data integrity services to an application host that hosts an application having application data, comprising:
storage for storing a restore point catalog; and
a processor programmed to:
obtain a micro-backup of the application, wherein the micro-backup reflects changes made to the application data over a period of time from when a last scheduled backup was generated and a number of changes to the application data exceeded a predetermined number, wherein generation of the micro-backup was not scheduled;
obtain a timestamp that delineates an end of the period of time;
obtain header data of the last scheduled backup generated for the application host; and
obtain an application backup for the application using the micro-backup, the timestamp, and the header data, wherein the application backup is usable to restore the application to a state associated with the end of the period of time.
2 . The backup management system of claim 1 , wherein the restore point catalog comprises scheduled restore points associated with previously-generated scheduled backups and micro-restore points associated with application backups.
3 . The backup management system of claim 2 , wherein the processor is further programmed to catalog the application backup as a micro-restore point in the restore point catalog.
4 . The backup management system of claim 3 , wherein cataloging the application backup as the micro-restore point in the restore point catalog comprises cataloging the application backup as the micro-restore point in the restore point catalog based on the timestamp and the application to be restored using the application backup associated with the micro-restore point.
5 . The backup management system of claim 3 , wherein the processor is further programmed to:
obtain a restoration request for restoration of the application to a state associated with the timestamp;
read the restore point catalog for the micro-restore point based on the restoration request; and
perform a restoration of the application using the application backup associated with the micro-restore point.
6 . The backup management system of claim 5 , wherein:
the processor is further programmed to make a determination that the restore point request is for a restoration at a micro-restore point; and
reading the restore point catalog for the micro-restore point based on the restoration request comprises reading the restore point catalog for the micro-restore point based on the restoration request and the determination.
7 . The backup management system of claim 1 , wherein the storage is further for storing a schedule of when the application host is to generate at least one of a full backup or an incremental backup.
8 . A method for providing backup services to an application host that hosts an application having application data, comprising:
obtaining a micro-backup of the application, wherein the micro-backup reflects changes made to the application data over a period of time from when a last scheduled backup was generated and a number of changes to the application data exceeded a predetermined number, wherein generation of the micro-backup was not scheduled;
obtaining a timestamp that delineates an end of the period of time;
obtaining header data of the last scheduled backup generated for the application host; and
obtaining an application backup for the application using the micro-backup, the timestamp, and the header data, wherein the application backup is usable to restore the application to a state associated with the end of the period of time.
9 . The method of claim 8 , further comprising cataloging the application backup as a micro-restore point in a restore point catalog.
10 . The method of claim 9 , wherein the restore point catalog comprises scheduled restore points associated with previously-generated scheduled backups and micro-restore points used to identify timestamps associated with previously-generated application backups.
11 . The method of claim 9 , wherein cataloging the application backup as the micro-restore point in the restore point catalog comprises cataloging the application backup as the micro-restore point in the restore point catalog based on the timestamp and the application to be restored using the application backup associated with the micro-restore point.
12 . The method of claim 9 , further comprising:
obtaining a restoration request for restoration of the application to a state associated with the timestamp;
reading the restore point catalog for the micro-restore point based on the restoration request; and
performing a restoration of the application using the application backup associated with the micro-restore point.
13 . The method of claim 12 , further comprising: making a determination that the restore point request is for a restoration at a micro-restore point, wherein reading the restore point catalog for the micro-restore point based on the restoration request comprises reading the restore point catalog for the micro-restore point based on the restoration request and the determination.
14 . The method of claim 8 , further comprising generating at least one of a full backup or an incremental backup according to a schedule.
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 providing backup services to an application host that hosts an application having application data, the method comprising:
obtaining a micro-backup of the application, wherein the micro-backup reflects changes made to the application data over a period of time from when a last scheduled backup was generated and a number of changes to the application data exceeded a predetermined number, wherein generation of the micro-backup was not scheduled;
obtaining a timestamp that delineates an end of the period of time;
obtaining header data of the last scheduled backup generated for the application host; and
obtaining an application backup for the application using the micro-backup, the timestamp, and the header data, wherein the application backup is usable to restore the application to a state associated with the end of the period of time.
16 . The non-transitory computer readable medium of claim 15 , further comprising cataloging the application backup as a micro-restore point in a restore point catalog.
17 . The non-transitory computer readable medium of claim 16 , wherein the restore point catalog comprises scheduled restore points associated with previously-generated scheduled backups and micro-restore points used to identify timestamps associated with previously-generated application backups.
18 . The non-transitory computer readable medium of claim 17 , wherein the method further comprises:
obtaining a restoration request for restoration of the application to a state associated with the timestamp;
reading the restore point catalog for the micro-restore point based on the restoration request; and
performing a restoration of the application using the application backup associated with the micro-restore point.
19 . The non-transitory computer readable medium of claim 18 , wherein:
the method further comprises making a determination that the restore point request is for a restoration at a micro-restore point; and
reading the restore point catalog for the micro-restore point based on the restoration request comprises reading the restore point catalog for the micro-restore point based on the restoration request and the determination.
