About MSDP remote office client deduplication
WAN backups require more time than local backups in your own domain. WAN backups have an increased risk of failure when compared to local backups. To help facilitate WAN backups, NetBackup provides the capability for resilient network connections. A resilient connection allows backup and restore traffic between a client and NetBackup media servers to function effectively in high-latency, low-bandwidth networks such as WANs.
The use case that benefits the most from resilient connections is client-side deduplication at a remote office that does not have local backup storage. The following items describe the advantages:
Client deduplication reduces the time that is required for WAN backups by reducing the amount of data that must be transferred.
The resilient connections provide automatic recovery from network failures and latency (within the parameters from which NetBackup can recover).
When you configure a resilient connection, NetBackup uses that connection for the backups. Use the NetBackup Resilient Network host properties to configure NetBackup to use resilient network connections.
See Resilient Network properties.
See Specifying resilient connections.
pd.conf FILE_KEEP_ALIVE_INTERVAL parameter lets you configure the frequency of keep-alive operations on idle sockets.
See MSDP pd.conf file parameters.
You can improve the performance of the first backup for a remote client.
