Configuration requirements for snapshot backups with NetBackup for SAP
Each snapshot type has its own hardware requirements, software requirements, compatibility with certain features, and the snapshot methods that are supported. Special requirements apply for specific types of backups. See the NetBackup Snapshot Client Administrator's Guide and the Veritas Support website for more information. Familiarize yourself with this information before you configure any snapshot backups.
The following list highlights some of the requirements that pertain to database agents:
Snapshot Client backups do not back up all database objects. Your backup configuration must include schedules to perform snapshot and stream-based backups. This configuration ensures that the entire database can be restored successfully.
On UNIX, the user identification and group identification numbers (UIDs and GIDs) associated with the files to be backed up must be available. The UID and GID must be available to both the primary client and the alternate backup client. The UID on the primary client and the alternate backup client must be the same. Similarly, the GID on the primary client and the alternate backup client must be the same.
Ensure that the data files reside on a volume or a file system that does not contain archive logs, control files, or executables.
The hardware and software that is required for the appropriate snapshot method must be installed and configured correctly.
NetBackup Snapshot Client must be installed and configured correctly, and the primary server must have a valid license for this option.
To perform off-host backups, specify the off-host in the backup policy and ensure that host has the software and permissions to mount the snapshot.
To perform Snapshot Client backups or restores, you need brtools version 6.40, patch level 36 or greater.
