About managing MSDP storage read performance
NetBackup provides some control over the processes that are used for read operations. The read operation controls can improve performance for the jobs that read from the storage. Such jobs include restore jobs, duplication jobs, and replication jobs.
In most cases, you should change configuration file options only when directed to do so by a Veritas support representative.
NetBackup includes a process, called rebasing, which defragments the backup images in a deduplication pool. Read performance improves when the file segments from a client backup are close to each other on deduplication storage.
See About MSDP storage rebasing.
The RESTORE_DECRYPT_LOCAL parameter in the pd.conf file specifies on which host to decrypt and decompress the data during restore operations.
