How Backup Express Works in a Cluster

Backup Express provides automatic failover and task retry support so backups are uninterrupted. Without cluster support, the job will fail.

Backup Express is cluster aware and displays the shared resources appropriately in the cluster. This simplifies defining backup jobs.

Cluster Backup & Restore Challenges and Criteria

Cluster enabled volumes can be on any node at any time

Backup Needs To:

Follow resource to any node

Migration can occur before, during or after backup

Ensure each volume gets backed up only one time

No data doubling or missed volumes

Define one backup definition to get resource on any node

Obtain proper base / incremental / differential

Restore Needs To:

Automatically know where resource was hosted in order to restore

Be able to restore to original location, without user knowing original or current volume location

Backup Express Cluster Backup Features

Backup Express is a fully cluster aware application

BEX heartbeat NLM

Each clustered resource is backed up once, even if migration occurs at any time

Backup to disk or tape / LAN or SAN

LAN free backup with Dynamic Tape Drive sharing in SAN

OES / NetWare Cluster Configuration with Backup Express

Backup Express client on all physical cluster nodes

Cluster client (cmagent) runs on MASTER cluster node

Backup Express brings up cluster agent on master node

Backup Express creates a Virtual Node (Master Cluster Node) -provides single view of all Virtual Servers

Simple configuration with “Cluster Lookup” function

Automatic or manual “scan” tool is available for physical and virtual nodes – adds nodes to Backup Express configuration

GUI is “Cluster Aware” and represents the Virtual Node with the cluster enabled volumes under it

GUI will show n+1 cluster nodes

Data mover runs on this physical node

Cluster Enabled Volume backups

Connect to Backup Express Virtual Node

Cluster API provides physical host of the Virtual Server

Connect to TSA on physical node hosting the cluster enabled volume

Data mover runs on this physical node

Backup During Cluster Migration / Failover

Cluster volume may be hosted anywhere

Backup will ultimately succeed even if the resource migrates multiple times during backup

Cluster volume migration to a new node causes task retry

Node failure on physical node will cause task retry

Data will backup through new physical node

Backup Express Flexibility with Cluster Volume Backups

Multiple cluster volumes can backup in parallel to multiple tape devices to increase performance

LAN free backup with Dynamic Tape Drive Sharing

SAN Resource Sharing (SRS)

SCSI reserve / release in SAN

Protects devices from being reset when in use

Implements Floating Tape Method

Payne & Wipfel (2002). Novell's Guide to Storage Area Networks and Novell Cluster Services

Backup Express Flexibility
with Cluster Volume Restores

Define cluster volume restore through virtual node

No need to know where volume was hosted during backup

No need to know where volume is during recovery

Data can be restored to original location or new location, with one TSAFS exception

Cluster Support Summary

Cluster enabled volumes can be on any node at any time

With Backup Express, backup will:

Follow resource to any node

Migration can occur before, during or after backup

Ensure each volume gets backed up only one time

No data doubling or missed volumes

Define one backup definition to get resource on any node

Obtain proper base / incremental / differential

With Backup Express, restore will:

Automatically know where resource was hosted in order to restore

Be able to restore to original location, without user knowing original or current volume location

Cluster Support Summary

Cluster Support for OES, SLES, Netware 5.x & 6.x, Windows and Unix

Simple Configuration with “Cluster Lookup” Function

GUI is “Cluster Aware” and represents the Virtual Node with the shared resources under it (clustered disks, SQL Cluster, Exchange Cluster)

If failover occurs during a backup job, the task will fail, but will automatically retry and succeed on another physical node.

Application support including GroupWise, MS Exchange, SQL Server, Oracle, etc…

Configurable retry time for failover

Features of TSAFS

Supported on NetWare, SLES and OES

Replaces GWTSA

File level backup/restore

GroupWise database lock/backup/unlock

Timestamping of user databases

Latest file system code and related development/support resources

Features of TSAFS

Cluster support - job continue on failover (don't have to restart job from beginning)

Cluster support - use cluster name rather than node name (facilitates smooth failover/resume)

Performance/read-ahead - Take advantage of higher-end hardware
