SAN storage is used by businesses all over the world to store their data. This type of storage is known for its reliability and stability, which is why it is often used in mission-critical applications. SAN storage can also be configured with data protection features that help minimize data loss in the event of a disaster. In this blog post, we will discuss some of the most important data protection features available on SAN storage solutions.
Data Replication
One of the most important data protection features available on SAN storage is replication. Replication helps to ensure that data is stored in multiple locations, which can help minimize data loss in the event of a disaster. SAN storage systems can be configured to replicate data to another SAN storage system, or to a tape backup system.
Storage Snapshots
Another important data protection feature available on SAN storage is snapshots. Snapshots provide a point-in-time copy of data, which can be used to restore data in the event of data loss. SAN storage systems typically support both full and incremental snapshots.
SAN storage systems can be configured to take snapshots on a schedule, or in response to an event.
Backup to Disk
Another option for protecting data stored on SAN storage is backup to disk. Backup to disk provides an off-site copy of data that can be used to restore data in the event of a disaster. SAN storage systems can be configured to send data to a backup server over the network, or to a disk-based storage system.
SAN storage systems can also be configured to perform deduplication and compression on data before it is sent to the backup server, which can help reduce the amount of storage needed for the backup.
Air-Gapped Backups
SAN storage systems can also be configured to create air-gapped backups. Air-gapped backups are copies of data that are not connected to the network. This type of backup can be used to restore data in the event of a disaster or to provide a secondary copy of data for Disaster Recovery purposes.
Air-gapped backups can be created by SAN iSCSI storage that support the iSCSI protocol. SAN storage systems that support Fibre Channel can also create air-gapped backups by using a SAN Switch.
Immutable Storage
SAN storage systems can also be configured to use immutable storage. Immutable storage is a type of storage that cannot be modified or deleted. This type of storage is often used for data that needs to be protected from accidental deletion or modification. SAN storage systems that support the iSCSI protocol can use immutable storage by using the iSCSI Persistent Reservations feature.
SAN storage systems that support Fibre Channel can use immutable storage by using the Fibre Channel SAN Lock feature.
Air-gapping and immutability are limited to only some SAN storage solutions. StoneFly offers SAN storage solutions that offer both air-gapping and immutability and many other data protection features as well.
Conclusion
SAN storage is a popular choice for businesses that need to store their data reliably and securely. SAN storage systems can be configured with a variety of data protection features that help to minimize data loss in the event of a disaster. In this blog post, we have discussed some of the most important data protection features available on SAN storage systems.
