10. 10 . The data backup system of claim 9 , wherein the processor is further configured to execute the one or more processor-executable routines to commit a full backup recovery point having a point in time end time based on a point in time supported by one or more archive logs backed up as part of a last log backup performed as part of a current full backup.
11. 11 . The data backup system of claim 10 , wherein the processor is further configured to execute the one or more processor-executable routines to assign a single version number to the single log recovery point that is lower than a version number assigned to the full backup recovery point corresponding to the current full backup, and wherein the single log recovery point is available for recovery to a previous full backup recovery point created before the current full backup was initiated and the full backup recovery point created during the current full backup.
12. 12 . A method for data backup that enables point in time recovery, comprising: sending a request to a data backup server to initialize a full backup storage space and a unique log backup storage space when a full backup is initiated; performing backup of one or more data files on the full backup storage space; performing backup of one or more archive logs on the unique log backup storage space such that the backup of one or more data files and the one or more archive logs is performed parallelly during the full backup; performing a log backup of one or more scheduled archive logs on the unique log backup storage space during the full backup once the backup of one or more data files is initiated; and completing any ongoing log backup or performing a last log backup on the unique log backup storage space once the backup of one or more data files is completed, and closing the unique log backup storage space.
13. 13 . The method of claim 12 , wherein the unique log backup storage space is initialized at a first time and the full backup storage space is initialized at a second time that is later than the first time.

Description

PRIORITY STATEMENT The present application claims priority under 35 U.S.C. § 119 to Indian patent application number 202441012336 filed 21 Feb. 2024 the entire contents of which are hereby incorporated herein by reference. BACKGROUND Embodiments of the present invention generally relate to data backup systems and methods, and more particularly to data backup systems and methods that enable point in time recovery by performing a full backup and one or more archive log backups parallelly. Enterprises these days seek reliable, cost-effective ways to protect the data stored on their computer networks while minimizing the impact on productivity. An enterprise might backup critical computing systems such as databases, file servers, web servers, virtual machines, and as part of a daily, weekly, or monthly maintenance schedule. The backup may be performed by storing a plurality of snapshots at predefined intervals. In the event of data loss or data corruption because of malware/ransomware, the backed-up data may be restored to the primary data source or another restore destination. The back up may include one or more full backups, incremental backups, and archive log backups. However, currently, database backups have gaps in point in time recovery range for durations of full backups, which could span days. This reduces the restore point optimization for the customer. In addition to this, there is cross dependency between full and log recovery points resulting in complications in recovery point expiry and restores.

In addition to the illustrative aspects, example embodiments, and features described, further aspects, example embodiments, and features will become apparent by reference to the drawings and the following detailed description. Briefly, according to an example embodiment, a data backup system configured to enable point in time recovery is presented. The data backup system includes a storage initialization module configured to send a request to a data backup server to initialize a full backup storage space and a unique log backup storage space when a full backup is initiated. The data backup system further includes a log backup module configured to perform backup of one or more scheduled archive logs on the unique log backup storage space. The data backup system furthermore includes a full backup module configured to perform backup of one or more data files on the full backup storage space, and further configured to send one or more commands to the log backup module to initiate and terminate the backup of one or more archive logs on the unique log backup space such that the backup of one or more data files and the one or more archive logs is performed parallelly during the full backup. According to another example embodiment, a data backup system configured to enable point in time recovery is presented. The data backup system includes a memory storing one or more processor-executable routines and a processor communicatively coupled to the memory.
