Backup and Restore Key Considerations

Backup to Disk vs. Tape

Capacities, configurations, features


Disk vs. Tape

Disk No single point of failure architecture No human errors in loading / unloading tapes Does not stretch RAID Always online Asynchronous Replication to a remote site Fast restores and easy to verify backups are correct

Tape Can be a single point of failure Human errors in loading / unloading tapes Tapes stretch and shoeshine Not online, slowing restores Not automatically sent to a remote site

1. LAN-based (no array-based snapshot) Data takes the full round trip, bogging down

application servers, the LAN, and the SAN

2. SAN-based (with array-based snapshot) Data is copied within the disk array or across the

SAN, with no impact to LAN or application servers

Protection Against Site-wide Failure Frequent snapshots are transmitted to target side Snapshots may be mounted on target side Backups may be performed at the target side Good way to protect remote/branch offices Failover / Failback to remote storage system Pause / Resume, checkpoint restart, deduplication

Why not de-duplicate right before the backup disk?

Inline de-duplicating appliances either slow backups or are costly

Application servers and networks become bogged down transmitting information that likely will not make it onto the backup disks

De-duplicating appliances fragment data, which hinders restore rates

To test the validity of a backup, a full rehydration of data from the deduplication appliance to a free storage pool is necessary, hindering restore time objectives

Backups cannot be quickly tested to ensure

they are correct with de-duplicating appliances

E-Series Snapshots (1 of 2)

Snapshot 1

Snapshot 2

Snapshot 3

Snapshot N

Snapshots of iSCSI, Fibre Channel, or SAS connected SAN volumes Snapshots are instantly taken Initiated via scheduler, manually, or scripted Microsoft VSS Hardware Provider to install on Windows servers Application-consistent snapshots for Windows servers Initiate snapshots from any VSS Requestor such as popular backup

applications Initiate backups from Nexsan Storage Tools Utility (a VSS Requestor) All security information is preserved for the volume at the point in time the

snapshot was taken Policy-based retention and deletion of snapshots Mount snapshots as READONLY for backups or to restore individual files or

entire volumes Mount snapshots as READ/WRITE for data mining and testing


E-Series Snapshots (2 of 2)

Rollback a volume to a prior point in time Volume is instantly available, even though the rollback is still in process for

that point in time Restore operations are reversible and all existing snapshots are preserved

(space permitting) Delete snapshots in any order Uses copy-on-write algorithm and requires data protection storage to be

pre-allocated Size of the data protection storage pool can be grown, and can flexibly

assigned to volumes Up to 4096 snapshots per volume or RAID set Easy to set up and manage via GUI Nexsan utilities to manage snapshots from Linux, AIX and Solaris

E-Series Asynchronous Replication (1 of 2)

IP NETWORK(LAN OR WAN)

E-Series

E-Series


Asynchronous Replication of individual iSCSI, Fibre Channel or SAS connected SAN volumes

Separate systems by any distance and communicate over TCP/IP One-to-One and Many-to-One Based on snapshots, which are retained on the source and destination sides

of the replication Can replicate older existing snapshots, as well as snapshots taken after

replication is set up Only the changed blocks since the last snapshot need to be transmitted Checkpoint restarts efficiently resume replication if the transport has a

temporary outage Can mount snapshots on the destination side while replication is active Full security is preserved for volumes on the destination side


E-Series Asynchronous Replication (2 of 2)

IP NETWORK(LAN OR WAN)

E-Series

E-Series


Manual failover to the secondary system on the destination side Useful for data migration to a new system or for storage rebalancing 128 concurrent replications, of which 16 can be active per system Easy to set up and manage via the GUI Replication can start when a snapshot is taken or on a schedule Replication can be paused, resumed, or canceled
