About archive redo log backup for PaaS workloads
NetBackup supports archive log backup for AWS RDS Oracle workloads. Archive backups reduce the full and incremental backup windows significantly.
In this method, NetBackup backs up the data that is changed since the subsequent full or incremental backup.
Guidelines for working with archive log backups for PaaS workloads:
It is recommended to keep the frequency of archive log backup in the protection plan under 24 hours.
While creating a policy, assign a longer retention period to full or incremental backups than to archive log backups. A complete restore requires the previous full backup, all the subsequent incremental backups, and all subsequent archive log backups. If the full backup expires before any of the subsequent backups, it may not be possible to restore all the files.
Use a single storage for full, incremental, and archive backups.
Do not expire random archive backup images. Expiring them may cause application inconsistency due to data loss. NetBackup relies on the previous full backup and all the subsequent incremental and archive backups for successful restore.
