How Veeam Plug-in for SAP on Oracle Works
Veeam Plug-in for SAP on Oracle functions as an agent between SAP BR*Tools and Veeam backup repositories. After you install and configure Veeam Plug-in, you can perform all backup and restore operations with BR*Tools. Veeam Plug-in compresses, deduplicates database backups and transfers them to a backup repository connected to Veeam Backup & Replication.
Veeam Plug-in for SAP on Oracle supports the following tools:
For details about these tools, see the SAP Database Guide: Oracle.
After you configure Veeam Plug-in for SAP on Oracle, SAP BR*Tools performs the backup in the following way:
- When you launch a database backup, BRTOOLS starts the services of Veeam Plug-in.
- Veeam Plug-in connects to the Veeam Backup & Replication server and creates a backup job object (if it has not been created before). Veeam Backup & Replication administrators can use this backup job object to monitor the backup process, manage backup files and copy the database backup to secondary repositories.
- BRTOOLS launches the backint BRBACKUP tool that uses the Veeam Plug-in configuration file as a initialization profile.
- Veeam Plug-in starts Veeam Data Mover on the SAP server and on the backup repository. Veeam Data Movers create communication channels for each backup data stream. Depending on the number of channels specified in Veeam Plug-in settings, there can be 1 or up to 32 parallel channels.
- Veeam Data Movers transport database backup files to the backup repository.
Veeam Plug-in stores backup files in the following formats:
- VAB: compressed and deduplicated Oracle database backup files. Veeam Plug-in creates VAB files for both full and incremental backups.
- VASM: metadata files that contain information about the backup. A VASM file is created for each VAB file. VASM files are used by Veeam Backup & Replication to get data about Veeam Plug-in backups.
- VACM: a backup job metadata file used to check synchronization with the database.
